• Cannot start Dell Studio XPS 9100 - is the PSU?

  These symptoms are compatible with a faulty PSU?

  I have a 4 years, processor Dell Studio XPS Desktop Intel i7 960 (expired warranty) 18 GB DIMM: 64 Bit Windows 7 ultimate OS.

  Computer will not start. (Dell 0M1J3H 525W) POWER supply has a green LED on the back of the envelope of the computer with a black switch diagnosis. When the computer reads the green light is on.

  If I press the Start button nothing happens - the white light on the Start button does not illuminate. But if I press the button to start for at least 12 seconds then release and press it again the logo Dell at the edge of the bezel turns on for a second and the fans turn at 20 degrees, but the computer does not start and there is no light on the Start button. The same thing happens if I press the black test on the power supply switch after the button of start for about 12 seconds. If I quickly press the test switch repeatedly from 40 to 50 times, four fans will turn a little bit but stop as soon as I stop to press the test switch. If a power is to learn in the light of the collar and the fans, but the computer starts and the green light does not go or flash. As directed by Dell, the green light is supposed to be activated when the current flows through the power supply and the green light is supposed to flash if I press the test switch when the computer is turned off.

  More Dell' diagnostic instructions I disconnected the motherboard and all the readers and the video card in the PSU, but the test was always negative, that would normally indicate a defective power supply.

  However, if the front bezel blinking on and fans to be powered for a fraction of a second, which excludes a failure of the power supply?

  GENERAL INFORMATION: One night several months ago fans have started racing as the computer was overclocking but my meter showed only 30% CPU usage. Computer subsequently began to lose power and restart at random times.  No crash dumps or stop. Just a loss of power and a reboot. Sometimes the auto restart would work and sometimes it wouldn't. When the computer restarts will not it will not re-start and there was no light white or orange, when I pressed the Start button. If I hold the start 12 seconds or more and then released it and press start logo collar flash momentarily, but no start and no other light. I would try restarts several times, sometimes by pressing the button start hundreds of times before the computer would finally boot. When you start the computer it would normally sometimes several days before losing power again.

  The last restart was more than a week and the computer normally lasted more than a week until yesterday when he lost power.

  I think that the power supply may be bad. But the only other time that I replaced a power supply on an old HP Pavilion. In this case, the computer was completely dead. I'm confused by the momentary illumination of the Dell logo on the collar and the shaking of the power to the fans. Which excludes a failure or default PSU?

  The button BIST says that the power supply is bad.  The BIST button isn't the power button.

  The LED on the back does not mean that the power supply is good.

  The BIST (built in Self test) is LED and button are for.

  Some Dell computers have power supplies that include a self-diagnostic function. The test for power button is visible at the rear of the system.

• Replace the power supply, computer does not turn on

  I had a Seasonic SS 560 KM power supply for my HP Pav e9280t.  I removed the old power supply while keeping the power cable is plugged in.  Then replaced each power cables one at a time in the new power supply and finally he attached to the tower.

  Now when I try to turn on your computer, it just boots barely upward.  I can hear the fans kick on for a second or two, then everything just stops.

  Since I replaced the cables one at a time I don't think I missed anything; MoBo, Fan of MoBo, 1 optical drive, disk HARD 2 and 1GPU.  The tower is open and I can see the fan, the fan GPU MoBo and PSU fan all hang on one second so that they get the right power?

  I must have missed something or possibly faulty PSU?  Any help will be appreciated.

  Hello Chadow86, it is possible to the new power supply may be faulty. I would check double all the connectors again.

  Since you mentioned the fan to the motherboard, it would not be necessary to unplug the CPU fan when you changed the power supply. The CPU fan power source comes from the motherboard and not directly from the power supply. I don't know what fan on the motherboard you are talking about.

  I watched the specifications and photos of the new power supply. It is a modular design. I would check the cables connected to the power supply to make sure that they are in the correct connectors.

  If the system still does not start, the cause could be a new power supply faulty.

  I hope this helps.

• Compaq Presario CQ4010F: Problem of block of POWER Possible on Compaq Presario CQ4010F

  Yesterday, the computer turns off by itself.  When I rebooted, it again stopped three times until finally, he wouldn't do anything.  Here are the troubleshoorting things I did so far: while the POWER supply light is on (not flashing) whenevery I push the Start button, the Start button light and the two connected fans, but the motherboard, as well as the fan on the flicker of the PSU momentarily, then there is nothing.  The light goes off, and whenever I have the light on unplug and plug the power cord in the same thing happens again and again.  This is after I unplugged all of the PSU except for the connector on the motherboard.  Could this be a faulty PSU?

  Hello

  You must have the connector 24-pin and 4-pin ATX connector connected to the motherboard. If you are still having the same problem then try a replacement power.  A competent local PC repair shop should be able to test your power supply.

  However, based on your other posts, you may have a bad mother in which case I suggest you a new PC.

• HP Pavilion p6-2: problems on blocking down after I installed the new power supply on a p6-2207ep

  Hi all

  B4 explaining my problem, I really don't know if I should post this in office, or material in this section of the freezes/crashes/locks but since I posted in freezing section and no results I decided to try here.

  My pc: http://h20564.www2.hp.com/hpsc/doc/public/display?docId=c03382032

  I bought a new PSU: XFX TS 550W 80PLUS BRONZE for the GPU upgrade 380 R9 I was planning to do.

  Is there some BIOS I get HP for this cause of power supply from what I read, if I not only one of the things like manufacturer reset to the factory settings may stop working... Currently, my Bios version is 7.11...

  Problems with the new power supply:

  When I closed windows 7, the first problem, the picture freezes on the screen that says "blocking windows down", I waited a bit and nothing, tried to turn off the machine while keeping down the power button but nothing to disable directly in the rear switch of the PSU...

  Second time happened a little different soomething, seconds after freezing again on the screen that says "blocking windows down" windows actually turned off and the screen is off but everything inside the computer case continues to flow fans in light of the power button / stop and was also able to close by keeping pressed power button...

  When I restart the computer, to which some time stops, and only after a few seconds, it turns...

  Also tried the GPU with the new PSU fans worked but no entry in the screen that I guess just a power supply problem.

  ATM, I'm RMA waiting to know if it is a power supply defective or not...

  Problems after the reinstallation of the original material:

  Some of the same problems when I got the new PSU remained namely:

  Windows actually stop and the screen is off, but everything inside the computer case continues to flow fans in the light of the button on / off and was also able to close by keeping the power button...

  When I restart the computer, to which some time stops, and only after a few seconds, it turns...

  What I've done so far to try to fix the problem:

  Restore windows 7 to a b4 point the hardware installation.

  Reset the BIOS

  Hard reset

  Clean boot

  Do you have a full checkdisk which means 0 KB in bad sectors...

  A complete hardware checked all tests with the HP software

  A system file check everything beautiful

  What I fear most is a faulty PSU that may have caused damage to my equipment mainly the motherboard, but could be something else entirely.

  Maybe I need a specific BIOS for that motherboard / PSU combo, but after returning to the source material, the problems remained.

  What I can do because I can only make the software tests since I don't have an extra PC to test the parts...

  Hello

  Disconnect all external devices except the keyboard and mouse when you try to solve the problem.

  Disconnect the PC and removed the CMOS battery.  Press and hold the power for 30 seconds.  Now, replace the CMOS battery and plug the PC give a TI a go.

  Your PC is not stable enough to make a BIOS update. Do not attempt to use the graphics card XFX until your PC is stable enough to make a BIOS update.

• Z820 - button Power LED blinks 4 times (red) with beep... bad card (Quadro 4000) graphics?

  Hello

  My Z820 at the office is suddenly having a few hardware malfunction.

  When I turn on my machine, the PSU/system fans don't rev and the Power LED button flashes red with a beep 4 times.

  According to this page of troubleshooting, this indicates a faulty PSU on the new UEFI computers:

  HP desktop - computer does not start and emits a LED or a beep Code

  Section "code beep and LED descriptions.

  Get the exact model of LED as the example of "power failure".

  Then, I got a new power supply replacement. I still have the exact same model LED and beeps...

  So, I have drawn deeper and found that when I removed the Quadro 4000 card graphics and then put on my machine, the power button LED is lit in blue (led code ' computer-S0 (normal operation) "") and all the normal spin fans.

  The Quadro card seems to be the culprit...

  Unfortunately, I have no alternative graphic card laying to verify this around, I'm waiting for a replacement of the graphics card (via HP service) to arrive tomorrow.

  Is it possible that the power LED button code (4 times red with beep...) has nothing to do with a bad power supply and that my Quadro is bad?

  Dries

  Dry... that Z820 has been giving you headaches.

  Many fault codes have not changed since the previous workstatons.  I hit this series of beeps of error in the past, and often doesn't mean that the power supply itself is the cause.  It can be a hardware device to the bottom of the chain causing a power surge to power, triggering his "crowbar circuit: fault protection

  http://en.Wikipedia.org/wiki/crowbar _ (circuit)

  Here are the instructions to deal with this series of beeps of a previous HP xw technical and repair.  Note the number 2 in the troubleshooting instructions... usually you don't have to go down to 3, in my experience.  I think that you have already found the faulty unit:

  Loss of power.
  1. open the access panel and make sure that the power cable is properly
  connected to the system board.
  2. Locate the faulty device by removing all devices and then reinstalling one at a time
  until the workstation fails. Replace the device at the origin of the failure. Continue to add
  devices to make sure that everything works correctly.
  3. check the power supply feature.
  a. turn off the AC power.
  b. remove all cables internal power on the system board.
  c. connect the power supply.
  ● If the power supply fan turns and the BIST LED lights, then the
  power supply is good. Replace the motherboard.
  ● If the power supply fan does not turn or the BIST LED does not
  light up, replace the power supply.

• XPS, a Microphone 27 catches almost no sound

  I had the XPS one 27 for about 4 months and the microphone has never worked.

  I tried to use the registration system through multiple applications and voice Skype conversations. No luck.  The saved files are of very poor quality (noise muffled, barely audible) and no partner of Skype (I tried with several people) were able to hear me other that a thud, inconsistent.

  It is imperative that my system has a microphone that works as I use it to record a qualitative research and hold business meetings.  This is the third question, I had with this machine (the first was a faulty PSU and the second is a squeaky/wobbly computer stand) and is not what I expect from a $2000.00 machine.

  Hi VictoriaDell,

  You can uninstall and update audio drivers by following the steps below:

  • Press Windows + X keyboard
  • Click on Control Panel
  • Click uninstall a program or programs and features
  • Uninstall the sound driver and restart the system
  • After the reboot, you can update the audio driver here
  • Follow the on-screen instructions and restart the computer when prompted

  If the problem persists, you can follow the steps below to enable the MIC boost:

  • Make sure that you are on the desktop screen. If you are on the start with tiles page, you can click tiles of Office to access the desktop mode.
  • Right click on the speaker icon to the lower right side of the taskbar in the notification area

  

  • Click on "recording devices".
  • A Sound windows appear on the screen a list of the recording devices

  

  • Make a right-click on the internal microphone (that you have posted in the screenshot)-> choose'Properties' -> make sure that the Microphone is set to 100 and see if the problem still occurs.

  

  • You can adjust the Microphone Boost to 10.0dB or 20.0dB and check if the record is better.

  I hope this helps. Please respond to the findings.

• System fan was able to start! Service system to avoid damage. Press [F2] to continue

  Ive read all the forums and eliminated the possibilities. This isn't a power supply fault, it's a whole new fan and I think I know the cause, but do not know how to fix it. I took the hard drive, motherboard and processor of my Media Center m7640n, added a new PSU and video card and put it in a new case from Cooler Master Storm Sniper Black edition games. I didn't get the error before the swap but had during the first boot after the Exchange. Ruling on a faulty PSU and knowing that the fan is brand new I am asssuming that I get this error because the new case fan is bigger and there by taking more time in the limelight. Problem is that the BIOS does not give me an option fan and theASUSteK motherboard is the property of HP and ASUSteK nor HP provide BIOS support. Any ideas? Please help because I do not want to spend the money to replace the motherboard, CPU etc...

  On my Pavilion is under the supervision of the material (I think, would have to reboot to check). There is a place to turn off fan analysis. Only if you are sure that your fan is working.

  Unlike other similar problems on the web, he won't go to the Toshiba start screen.
  Screen stays black! When I try first to power, I hear only a few sounds DVD player nothing else.
  When I try to reset it now button / stop for 30 seconds or more, I hear hard drive (or power) sound, but nothing happens.

  . I am writing from the same laptop. If I stopped it now, it will still take me 30 minutes and many random combinations of hard reset to make it work.

  Someone suggested that the power output of the card could be a problem. can we check voltage output without fancy electrical appliance?

  Help, please. I can't afford new laptop right now.

  > I have reset hard randomly wihout battery powered, with battery without power and without battery without power. After many attempts it suddenly starts normally and works fine afterwards. It is since the last days of thre appening. whenever I have stop, I have to do

  I'm afraid there's something wrong with the motherboard or the part connected to the mobo as RAM modules m.
  If you have not checked the RAM modules in the past, I'd recommend this as faulty RAM could affect the functionality of the laptop. In addition the RAM modules are not very expensive, so it s worth to check the following items.

  But please don t understand me wrong. I put t say there is a problem with the RAM. I said, this could be the troublemaker. So please don't be disappointed if this workaround solution would not help.

  You are really funny to type cuban_cigar. And you are telling stories. But I want some of your stories were real and not made up from thin air.

  You posted links to the son how to get rid of the BIOS password ok that nice, but it would be nice if you had read EACH case before posting something like this. In most cases, the user has lost the password!

  I've got three different models of Toshiba laptops and set to update the BIOS on all laptops.
  Never ever had a BIOS password problem!

  I'm agree with Akuma and possibly that a single mobile model may be affected by unknown BIOS password problem.
  I noticed an assignment abut M70, but it seems that the ASP took free and new update of the BIOS should help.

  I also read in other forums that something like this happens also on mobile phones from OTHER manufacturers.
  So in your case, I would be very careful with some things that are not known to you or not really clearly for you because you confuse others here in the forum.

• My Satellite P300 does not illuminate

  My Satellite P300 (PSPC4A - 03Q 018) switched on me unexpectedly while I was playing a game. I noticed he was running a little hot (it was on a level with clear vents office). I checked the time CPU. with the software and it showed levels up to 80 c while just browse Internet and up to 100 C + all playing games.

  So I blew the vents with compressed air - no change.

  After a little research, I decided to renew the thermal grease. The pulling down of some of the fat has hardened as it seems like a useful exercise. After putting together I have nothing. The only life that I had was a quick flash of the LED AC (the symbol of the plug on the front of the palm rest) when I plugged in, but that's all.

  What I've tried so far: I stripped down and everything reinstalled at least three times. This includes the processor, even if I didn't remove it at the beginning when I replaced the thermal grease. I reinstalled all the cables. I tried it with just the battery, just the AC line and at the same time. I tried to remove the RAM chips and put one by one in different locations. I tried to remove the battery and the AC, holding down the power for 30 seconds button line and try again with just the battery, just the AC line and at the same time.

  I think I either ESD'ed the card or mother or other component/s but I hope it is something much much painful/cheaper. Any suggestions?

  Thank you

  Hello

  Sounds that something bad happened to your hardware for laptop
  Maybe the RAM modules are faulty or the motherboard.
  I think that no one here would be able to tell which part is malfunctioning.

  What to say; If you n t know what part is affected, so I recommend asking a technician for a short control, I mean it is the best step before buying parts including don t need to be replaced

  After the hardware parts have been checked, you can decide what you want to do. sell this laptop faulty or replace parts
  But the new motherboard is not cheap...

• Installation of RAM-> black screen

  I bought iMac 5K, end of 2015 and has decided to increase the RAM by myself.

  I chose this model: HyperX Impact SODIMM - 16 GB Kit * (2x8GB) - DDR3L 1866 MHz CL11 SODIMM part number: HX318LS11IBK2/16.

  The problem is that when I install the RAM and put it on the iMac just goes to black screen. I hear the fan rotation, but no other noise whatsoever. Nothing. I tried adding to the old RAM, replace etc. I can turn on the iMac with the original 8 GB of RAM installed.

  Anyone know what could be the problem? Is this a faulty hardware?

  I would stick with the purchase of your memory of one of these sellers: OWC, DataMemor Crucial. Each has methods to determine the correct memory for your computer. Memory HyperX is not really intended to be used in Macs. One of the three providers can provide you with the right product.

• Satellite L350-171 dead after 2 weeks

  Hi all

  I bought a Satellite L350-171 2 weeks of Tesco Direct. Went to the Toshiba brand because of rumors of reliability. A few days before, the computer could not turn on. Tried unplugging the charger/etc, but no joy. Called Support technique of Toshiba who said it looks like a hardware failure. No lights on the front - normally a yellow light indicates when the charger is connected. The charger is off 19V so I'm sure that's not the issue.

  The last thing that happened was a Windows update that requires a restart, but there is no way a software problem will result in the hardware failure.

  Toshiba suggested I ask Tesco for a replacement as it is less than 28 days old (which I did!). My questions are:

  (1) what type of hardware failure can cause the cell go dead without showing any sign of death?
  (2) the Satellite L350 series there the problems known - this happen with my replacement?
  (3) I am wrong to believe in the reliability of Toshiba?
  (4) anyone suggest some things I can try to bring back to life?

  Thank you

  I'm sorry to hear you have such a problem with your laptop. my brother has had similar problem and ASP has set in only 5 days. Now he's happy again with its A300 Satellite again.

  (1) what's happening with your laptop? It is not easy to say what was wrong there and we can only speculate on this but I think that the ESF may be responsible for this. Faulty electronic board I assume.
  (2) this can happen with all computer laptop and we cannot say that this can happen on Satellite L350 only. If you want you can check out this forum and see what write other people on L350.
  (3) this problem can happen with 1,000 other products too. If you buy a Ferrari and gearbox is defective after only 100 km would you buy Ferrari again? I think you're going to do this. ;)
  (4) according to me, there is nothing you can do. Try to get the replacement.

  Good luck!

• Vertical lines on the Qosmio F10

  Hello
  I bought this F10 in Poland 18 months ago so warranty has expired.
  I would like to correct and revive only if the repair costs will not go on the purchase of a new brand. I send you a few screens, so it may be useful to diagnose the problem. I hope that this is not the case, to get the new graphics card.
  There are also the new keyboard as friend coffee spit on it. Something about 1 month later, after that an accident like coffee, computer laptop went crazy, display seems to be damaged (as on the screens), fan is running at full capacity and windows only run in safe mode with the parameters of the low screen - 800 x 600:4 bits. However I am able to change the resolution to 1296 x 800:32 bits, but the laptop works even more slowly.

  Is there a chance that I can fix this? Let me know.
  Radek

  I agree with Jonny. For me, the worst case scenario for damaging the material is so portable crashed or separation liquid in keyboard.

  I imagine that the replacement of the material will be too expensive and best solution is to sell this laptop faulty and buy a new one.
