• Installed a new power supply, run only windows XP.

  So I recently replaced my power supply, and all respect that seems to be going very well that the computer has no problem running. However, every time I start the computer, it start in Windows XP and immediately requires me a check on windows XP. A screen will appear asking if I would like to activate via phone or internet tool. If I use the online detection tool, he suggests, he says that I can not connect to the internet and sends me in return. If I call the number, I can possibly a recording of the voice asking me the code 40 numbers on my screen. Whenever I enter this code by phone, he says he does not recognize that code and I'm at square one. So basically, how can I get my computer to start as it has always, in Windows 7 and with all my usual data?

  Also, I tried to start in safe mode with command prompt. When I get to the menu Startup and recovery in system properties, it appears the only operating system default is "Windows XP Media Center Edition. I have several hard drives my best guess is that it maintains launch than bad. Any help find how launch of correct would be greatly appreciated.

  TLDR; New power supply, computer guard run windows xp and by asking for activation, when I was previously with windows 7 for more than a year.

  Good guess:

  When you have reconnected all cables in your PC after installing the new power supply, you connected the SATA (data) cable that should go to your primary (generally marked 0) SATA port for a hard drive that has Windows XP on it.

  Check your cables.

• Power supply selection guide

  This MOD can make a post-IT.

  Here is a general guide on how to select a power supply for your HP desktop computer.  The majority of the standard ATX power supply (PSU) must fit in an envelope of HP.  The exception would be a slim casing or the esoteric Merle.

  Looking for a certification 80 + on the PSU to save electricity.  A PC is normally idle or operate at low load 75% of the time.  Therefore, to find a power supply which is more effective in the range 50 - 90W.  A power supply 80 + 350W reaches the level of efficiency of 80% at the exit of 70W (20% of rated output).  The output must be greater than 140W to achieve the same level of efficiency of a PSU of 700W 80 + equivalent.  So choose a power supply that is rated at 25% more than the maximum load of the ACTUAL spending of the rig you will save more of $ on electricity.

  A modern PSU is designed to achieve maximum efficiency between 20 and 80% of the nominal power.  Running a power supply above 80% charge level will result in excessive heat, noise and premature failure.

  A platform Nvidia GeForce GTX 280 (1024 MB of RAM) will rely on 350W max to the wall.  Taking into account the effectiveness of a block of power SUPPLY 80 +, the actual load on the power supply is only 280W (350 x 0.80).  To calculate the required power supply, multiply the actual load by 1.25 (25% margin).  In this case we only need a PSU 350W (280 x 1.25) to run this GPU.

  Let's apply what we know of a rigging of Radeon HD 4870 (512 MB RAM).  290W max to the wall.  Actual load is 290W x 0.80 or 230W.  Now, apply the 25% margin rule and we come to a requirement of 290W PSU (230W x 1.25).  Even if we apply a safety margin of 50%, the power required is always under 350W (230W x 1.50).

  There are no overspec need the power supply by 50%, unless you run your PC up 24/7.  Don't forget that there is a huge variation in the quality of the PSU and side.  Maybe a good 500W PSU is not able to provide as much energy as a quality 350W.  Antec Earthwatts/NeoPower/TruePower and Corsair Seasonic are widely available at several American retailers of quality units.

  High-end power supplies number will need additional power supply PSU in the form of one or two 6/8 pin plug GPU.  You can buy an adapter to convert a molex 4pin to plug 6-pin power of GPUS.

  Hi Nautsj,

  You need to open your PC and measure the physical dimensions of your diet. Here is a list of the things to consider:

  1. technical characteristics
  2. the total power - important
  3. amperage 12 + v - important
  4 modular - is not required, but I like the flexibility
  5. guarantee
  6 i7 and SLI ready
  7. energy efficiency
  8 cost
  9. size - standard ATX PSU is 5.5 "by 5.9" by 3.4 "give or take a few tenths
  10. a single + 12 volt rail is a better choice.

  www.Newegg.com has many choices of power supplies. Corsair, OCZ, Rosewill, Thermaltake...

  The typical EVGA GTX 570 in 9 "long.  The adjacent slot on the PCI-E x 16 slot must be vacant.  Open your PC and do some measures so that you know for sure if the card fits.  According to me, it will fit.

  For what is a PSU, Corsair CX600has very little growth, but the Corsair HX650gives you plenty of space to grow.

  I use the HX650 in two PC.  It is a modular model in order to have better options with the selection of cable.

  "How-to" HP articles should be useful.

  TIP: When installing the power supply, unlock the scanner and slide it forward to facilitate the removal and installation of the new power supply.

• With Tecra750DVD power supply problem

  My laptop recently decided to refuse to turn on when I turned on. There is a yellow light in the position of "power" over the front of the machine, but it won't start. I tried all the options: Power Supply Unit only, only battery, Power Supply Unit + battery and nothing works. Fuse is good in the plug of power supply. Battery is less than 12 months.

  Hello

  You can remove the battery completely when problemshooting this kind of predicament.

  First of all - what impression the power button? Does it feel as it should? Refers to how it used to feel? If this is not the case, check if there is an active "lock" behind it.

  Some models have a safety lock to keep the machine from accidentally start in a bag or two.
  Please look at the LED that indicates that your adapter is connected. When you try to switch the machine on, what is happening with this LED? Always the same fixed green light or suddenly out or flashing?
  If out, please try to get your hands on another adapter (borrow prefferably). If it flashes then try to remove the AC adapter, remove any option that can be easily removed, CD/DVD, memory, expansion card PC and so on.
  Try to restart it (remember to join HQ again). Even? If Yes, then sorry to say I think that your machine needs service. If this isn't the case, then there could be hope.

  Disconnect the AC and put back in place the units that you have deleted before, one by one and after each unit, try to restart the machine.
  If it starts fine, remove the unit and reconnect the next unit. Perhaps you will find that there is a problem with an external device (memory, CD, PC Card and so on), then at least you can continue working more or less as before the problem.

  Good luck

• My new power supply work with my motherboard?

  Hello

  I reasontly bourght a few upgrades for my PC.

  I bourght an i7 870 and an AMD 5670 + a new power supply

  So my question, what ive in doubt, my new PSU(CX-500) work with my motherboad (MS-7613(Lona-GL8E)?

  Thanks in advance

  René Tyrsted

  Thank you.

  Yes. It will work.

  However you will probably find a little tight because of remaining unused cable bundles. My preference for the PC ATX Mid-size boxes are of the modular power supply. With a modular power supply connect only s connector as much as you want.

  Do the upgrades one at a time.  Start with the power SUPPLY and any other origin. Check that it works and then close.  Then go to the graphics card.

  Happy update.

  Best regards

  When the operating system is loaded is recognized correctly battery?

  In any case, this behavior is not normal and maybe you should contact the nearest Toshiba service provider and ask for help. They can check the battery and the power supply electronic and see what's wrong here. The warranty is valid if new battery or repair will be free.

• ThinkPad T410 boots only if the power supply is plugged

  Hello

  I have a really strange bug. My thinkpad T410 (2537-UQF) with an OCZ Vertex 3 SSD boots only if the power supply is connected. If I have a full battery, and try to boot without the power I get a blue screen after about 60 seconds on the screen where the windows logo appears. I have Windows 7 installed fresh a few days ago.

  I think its possible, I've done a few failure with drivers. The power management ThinkPad always stops working after startup. So I deleted the program using the feature "msconfig".

  I'm not really sure what I can do about it. Any idea?

  Thanks for any answers in advance & regards

  Rain

  OK I solved the problem:

  The workaround is to set to battery power settings in the BIOS to auto. If the power in the Bios settings are on maximum battery life, the system does not start if you use the SSD OCZ Vertex 3.

  Hope this helps everyone who has the same problem. I need 4 days to understand this.

• Propeller works only with external power supply

  Hello

  Just got my Helix and I have some published, one of the biggest problem so far is that it will only fuel upward and stay on with external power supply, when I dock this works very well, if I disconnect it it stops, if I plug the power supply into the Tablet light it up, but as soon as I remove the power cord it will turn off I checked and the batteries are charged, any advice at 100%?

  Thank you

  Thanks for the reply, I called Lenovo technical support and they thought it was the motherboard, technology has changed and he made similarly he suspected a defective battery, it replaces and it works fine now, so it was a defective battery on the Tablet, was not getting charged, Lenovo technical support was great, fast and very apologetic the laptop so far, thank you for all the help that love.

• video card (recommended 300 watts) with the power supply only of 280 watts max.

  What are the risks of having a video card which recommends 300 watts connected to a computer that has only 280 watts? The only risk I know is maybe crashing, freezing and restarting the computer. It will damage also any hardware in the computer?

  Yes, you may damage other components as well as the video card. It is quite inexpensive and easy enough to replace a power supply with a new supporting material you want to run. MS - MVP - Elephant Boy computers - don't panic!

• G4 MDD power supply Issue

  My MDD was recently stop only two or three minutes after a cold start. The power led lights up, the gray screen with the Apple logo appears with the spinning wheel, but then the machine suddenly loses power as if the power cord was disconnected. These are the things I've already tried:

  1. Removed the PRAM Battery
  2. Disconnected all devices except the keyboard and the monitor
  3. Tried a different power cord

  Start in safe mode did not help. The fans are all running, the red LED lights on the logic board and disk drives seem to work. This could be a power supply issue or a problem with the motherboard and is it possible that I can definitely identify the problem without being able to start the G4? The startup time has been considering more when everything worked last week, would that be a clue? I've owned this machine for more than twelve years and it put to the test so I wonder if it's time to retire him.

  Thanks in advance for any help you can offer!

  Hi, looks a lot like a problem of heat from the CPU, thermal paste is usually good for 5 years or more.

• Pavilian A4313W: Power supply for Pavilion A4313W

  Get technical support for my mother. She got an A4313W of Pavilion, which has a default power inside. Which is a specific power supply, or a work of a generic cannot in this system?

  If it's specific, can someone give me the part number for it?

  HERE IS a GENERAL GUIDE for this model of PC.  It seems to be a standard power source, so you can replace it with a generally available device rather than ordering a unit # part.  Don't forget to check the dimensions, however.  Also, IMHO get a higher power than listed unit is only 250w.  I would get at least a 400w unit and they are reasonably priced, too.

• Z640: Upgraded the video card to 1070 GTX. I have to upgrade power supply?

  @MacTheSteve, welcome to the forum.

  This is Service and Maintenance Guide for the workstation.

  I contacted StarTech to see if they would have an adapter 'Y' which had two 8-pin power connectors.  However, those that they should be the following on your motherboard or the power supply:

  StarTech Brandon: basically, there are 4 SATA power or LP4 molex.

  I believe that your diet is enough power, but simply do not have the required connectors.  At least, I don't the seen on the diagram of the motherboard.  It seems that you need to upgrade the PSU.

• Satellite U500 - 11 C - power supply unit not detected

  Hello

  on my Satellite U500 - 11 C, the power supply is no longer recognizes (the rest green LED turns off when I plug)

  I tested my diet and it's OK

  I disassemble my laptop to check the connector and the power is OK of the external connector to the connector on the motherboard.

  with my battery, the computer works normally (but the battery is not more)

  You have an idea on how to solve this problem?
  What can I check?

  > Do you have an idea on how to fix this?
  If the battery and the mains adapter are ok, while a single problem can cause this: faulty motherboard.
  Maybe there is something wrong with the electronic power supply on the motherboard.

  Of course this is only my personal opinion, but I put t see any other reason for that

  He started using the battery instead of the power supply.
  Power and battery leds turn on and turn off (on during a few seconds and then off for a few seconds).
  At this point, the battery stops charging.

  In the manual it mentions something on one of the lights turn blue, none have ever done that.

  Hope someone can advise
  Thank you

  Hello

  In my opinion, you should first check if the power adapter is not a malfunction.
  If the AC adapter would work properly, then the battery might not be charged and the battery led not turn to blue because the battery is not fully charged.

  I would recommend so check the AC adaptor first.
  Of course this is only my personal opinion and I could be wrong too
