  Hello

  A few weeks ago, I turned on my PC and it showed at the Compaq screen and then went to a blank screen & would not respond. I held the switch button to turn it off and after 4 attempts, it start fine. Next time, it took 20 attempts to initialize and now it does not start, it will be maybe if I try like 100 times he can do... The problem is when the Compaq screen comes up it comes only for like a second so I know that it does not start, if the Compaq screen stays for a few seconds as 3 + I know it will load windows and start.

  History > the computer originally had XP and has been replaced with VISTA memory was 2 * 512MB, but it was a bit slow and I was advised to upgrade. I bought 2 * 1 GB memory and put it in my PC a few months there may be 5 + had no problem so far.

  I tried the following:

  Remove the memory and replace it. Remove the 2 * 1 GB of memory and its replacement by the Moose 2 * 512MB to check if the memory is at fault.

• Mackbook Pro ME664LE/A does not start - only fan comes on

  MBP ME664LE/A - A1398 (EMC 2673). MacBook Pro Core i7 2.4 15 "beginning 2013.

  During an Office Update, the MBP began to operate the fan periodically. The MBP was not hot. After a while her display off (black) and the MBP has failed.

  Whenever I want to turn it on, only the fan turns on.  I followed all the procedures to get back to zero and also SMC reset, but nothing change.

  Any Suggestions? Could be a known problem?  Someone in the the Argentina Macusergroup said that apparently a known issue related to the card mother apple in 2013 models...

  The MBP has little use, only a few weekend for personal staff... I am concerned, I spent a lot of money in this MBP to get the best laptop at home, and it's a failure...

  Connect the MBP to a monitor.  If the monitor does not display an image, the main suspect is a faulty GPU.  If the monitor displays an image, the display or the connection to the screen is defective.

  Ciao.

  Hello

  No saving necessary data and re-installing Windows Vista might be the best option, but here
  are a few others.

  You can save your files by putting the drive in another computer as a 2nd disk (best) or external
  Drive USB enclosure and then backup to removable media such as CD, DVD or other USB drives.
  Of course a real store of the computer or the manufacturer of your system can help to recover the files.

  Or you can use a boot Ubuntu CD to back up data.

  Use Ubuntu Live CD to backup files from your Windows computer dead

  --------------------------------------------------------------

  You can access Mode safe? Repeatedly press F8 as you start? If yes you can try Control Panel - device
  Manager - graphics card - Double click on - driver tab - click on UPDATE driver - then right click
  on devices and UNINSTALL - REBOOT.

  A method to try to get to the desktop (try in normal Windows Mode without failure) is CTRL +.
  ALT + DELETE - Manager tasks and tab process EXPLORER.exe and COMPLETE the PROCESS on this subject - and then
  on the Applications tab - lower right - new task - type in EXPLORER.exe. Safe mode is available by
  repeatedly tapping F8 as you start. CTRL + SHIFT + ESC also begins the Task Manager.

  First check this thread in case it is simple and if not to come back to this thread.

  Black screen problems are extremely difficult to repair and all patch is usually on a base hit or miss.
  That there is no information on a black screen as it is on a blue screen just adds to the
  Difficulty. Often using a restore point or Startup Repair will have no effect. You can try a
  Google to see the proposed repairs, whom some have worked however these cover a wide
  field efforts.

  Here's a video of one of them.

• (Vista) computer does not start properly (Please HELP)

  My guarded vista stop without known reason. He started up the main login screen and I could connect. After that so long it would just turn off. I did a system restore, system repair at startup and F8 pressed and is entered in safe mode. Now, I have a new problem. He worked for a few hours. Enough to do a bit of homework. Then suddenly it disconnects and begins to do the updates for windows. Then it goes to a black screen and tells me what he planned for a clean disk. So he goes through this process and restarts. Now it is impossible to get pass Part 3 of 3 updates and it just stays at 0%. He will remain on this page for about a minute and just keeps restarting itself. I tried F8 again and cannot get into safe mode. WHAT IS WRONG WITH MY COMPUTER HELP ME! (PS: now I use my laptop which is a XP!) Help, please!

• T420s does not start. "Fan Error" appears with two beeps

  Lenovo Thinkpad t420s

  To the power, it goes to the ThinkVantage screen becomes black with "Fan Error" then stops.

  Using the ThinkVantage button has no effect.

  Everything was working fine a few hours ago, but now it seems that the main CPU (left rear) fan is no longer running.

  Is it watered or could there be a way to solve this problem?

  When the fan error fires always your fan or the motherboard is at fault and would require repairs under warranty.

• Reinstallation of Windows XP Home Edition (new hard drive) does not start properly, please help

  I have a HP Pavilion zd7000 that bad on the hard drive. I bought another and used the reinstallation disc to reinstall Windows Home Edition.  Everything seemed to go well, but it starts now to a HP Invent logo black screen that says press F10 to go together to the top and F12 at startup of Lan.  Then, a second black screen appears that says press F1 to resume or F10 Setup.  I press F1 and Windows loads very well.  What can I do to have Windows load immediately without going through this?  Any help will be greatly appreciated!  Thank you much in advance!

  EverWin... IT WORKED! I can't THANK YOU enough!  I've been to every site I could find... begging someone to help me.  Audit throughout the day (for a week) to see if someone had answered... tried everything!  I'm so happy (and tired) I could just cry.  I can't believe that you took the time to help me...

• Computer does not start properly, but it doesn't work in safe mode?

  When the computer is turned on, it begins with pink vertical lines in the splash screen and then primer not correctly. I am able to get safe mode and operated from there. I did system restore, memory, virus scan without result. Any ideas?

  You may have problems with your graphics card.

  If under warranty, contact the manufacturer of your computer.

  If this is not the case, try a local computer repair shop.

  See you soon.

• Inspiron 620-7750 Radeon with 450W power supply installed does not start

  Hello!

  I have looked EVERYWHERE online and on the forum and have seen several posts on this topic and still not found a solution that works.  I have a Dell Inspiron 620

  • I5Intel Processor2nd Gen Core i5-2310 / 2.9 GHz
  • Memory8 GB / 8 GB (max)
  • Windows 7 Home Premium 64 - bit Edition operating mode
  • Optical DriveDVD±RW
  • Graphics technology ProcesseurIntel HD Graphics 2000 dynamic video memory 5.0
  • Integrated graphics controller

  Recently, I buy a Powercolor Radeon 7750 graphics card I have installed the drivers, uninstalled the current Intel Graphics driver from Device Manager and then install the new card.  I of course unplugged the PSU got rid of and left in power has failed to myself and plugged into the PCI-E.  After I tired to turn on but it does not start.  Fans begin to turn, including on the graphics card, but nothing comes up on the monitor and it won't start.  When I unplugged the 7750 card it starts very well?

  At first I thought that it was not powered ridiculously horrible 300w PSU they put so that I have upgraded to an a 450w.  Everything works with the new power supply installed without the card, but as soon as I plug the new map, he continues to not start as before installing the card.  I have searched and tried things for 2 days now and CAN NOT find a solution.  I know that the 620 does not access the menu of the BIOS under settings in advance who does not help (don't know why Dell would never think it was a good idea!) so I can't change anything in there.

  Please, any help would be fantastic!

  Thanks in advance!

  The card is a bad card.  There should be ZERO problems with the supply of the stock 305 w and a 7750.

• Computer does not start after the screen of the bios, Compaq Presario SR1023WM

  Ok. Trying to fix a friend's computer and seem to have met a strange barrier.

  Problem: The computer does not start after the bios screen.

  Details: When you turn on the computer, the compaq logo with intel inside is and has the < F1 Setup > and < F10 System Recovery > options listed as well.  And that's it as far as the computer becomes.  After that the computer just locked up, no work of buttons on the keyboard lights keyboard ect ect.  I tried the puree on the F1 key, as soon as I turn on the computer and I can handle so he can say * entering setup * but it freezes again after this point.  I already tried to eliminate the possible sources of the problem, removed all expansion cards, HDD and Dvd Rom module only disconnected, only memory (256 MB ddr 2700), power, vga and keyboard connected.  Ive also used the jumper on the motherboard to clear the cmos, hoping that would solve the problem without success.  I tried using a different memory stick and different memory as well...  Tried to use both a ps2 and a usb keyboard... Ive even tried pulling the rider for the protection of the bios password (even if she did not have a password on it, just try everything I can think of).

  The installed bios version is 3.1, and that's all that I know on the computer at this point, except that the website tells me to him.

  http://h10025.www1.HP.com/ewfrf/wc/product?product=411354 & LC = on & CC = US & DLC = in & Submit.y = 5 & Submit.x = 3 & lang = to & CC = US <-link to the Web page for the model #.

  I'm basically at a loss on this one, so if someone feels scroll line-by-line of their brains on this one, I'd be very happy.

  I have a pretty strong understanding of computer repair, so feel free to give me something to try.

  If you need more information out of me, let me know as well.

  Try to clear the CMOS again but this time remove CMOS battery and hold the power button on a few seconds. Replace the battery, then try to start back to the top.

  At the back of the pc is the condition of the PSU led green or flashing?

• Satellite L100 - cooling fan does not start up more

  Hello

  On my L100 laptop cooling fan doesn't seem to work! It does not start up more and after awhile the laptop shuts down as it is too hot. What can we do?

  See you soon
  Mark

  Hi Mark,

  The fan lights normally the POST process before loading the BIOS. Your laptop will continue to boot normally, I presume that your fan control electronics is still viable, otherwise the MESSAGE would fail. So, it seems likely that the problem is with the fan itself. I suggest you check that the fan will run in fact and it missed upward (try to blow strongly in grids).

  If you laptop is still under warranty, then you must contact an ASP to get the fan replaced.

  Kind regards
