Cannot Boot

I was changing my MSE settings and it asked me to restart, but when I did I found that my computer crashed before it was able to boot.

Now it crashes every time it tries to boot right before it gets to the login screen at the Windows logo and then restarts.

I've tried using Windows RE, but it does not respond to keyboard or mouse input. I also tried booting from the Windows 7 CD to reinstall the OS, but with similar results.

I cannot get any farther than the first screen because it does no respond to any input. I am unable to access the advanced boot options screen with F8.

Sometimes during the startup process I am able to get to the BIOS options, but sometimes it does not respond to keyboard input even then.

I tested the RAM with Memtest and it said that it was working with no errors.

I am using Windows 7 64-bit Home Premium with a standard keyboard and mouse. Can anyone help me with this?

  1. Try F8 again, u need to keep pressing F8 button during BIOS start up.
  2. Did u do anything else when it started, except that MSE thing? Any HW changes?
  3. F8 does not seem to work. I am pressing it during the BIOS startup and during the Windows startup, but nothing happens.

    Nope. It was also doing a virus scan, if that helps.
  5. OK, can u post CPU+PSU+RAM - how many sticks+Mobo model name.

    New install or older installation...?
  6. Plus video card model.

    CPU: i7-950
    PSU: XFX Black Edition P1-750B-CAG9 750W
    RAM: G.SKILL Ripjaws Series 12GB (3 x 4GB)
    MB: GIGABYTE GA-X58A-UD3R
    I built the computer last year and have experienced no problems with it until now.
    EDIT: GPU: two 6870s
  8. U don't have to much power to spare : )

    How many HDD's?

    Good way to test it is to remove one GPU, that could eliminate the power shortage, if there is one.
  9. Is anything OC'd?
  10. The CPU was slightly OC'd, but I don't think it overheated (it has a Noctua NH-D14, if that helps).
  11. Is there any log it creates when it overheats (to verify if it did)?
  12. I put your specs in and it recommended 760Watts PSU

    One OCZ Vertex 2 OCZSSD3-2VTX120G and one SAMSUNG EcoGreen F4 HD204UI.
  14. I think it is PSU, can u remove one GPU? It may solve your issue.

    That's just a bit over what I have. Should I take out a GPU to see if that's the problem? EDIT: ninja'd lol

    Let me try that.

    Try HWmonitor @ http://www.cpuid.com/softwares/hwmonitor.html
  18. It didn't work. The same problem happened.
  19. nikorr said:

    I don't think I can do that because I can't boot into Windows. Is there some way to use it as a bootable disk?

    No F8 as well?
  21. nikorr said:

    Yes. When I press F8, it never gets to the advanced boot options screen before crashing.

    Right, did u tried it with one card only?

    BTW, I would remove the other one now and try it again. Its great PSU though.
  23. U don't have an HDMI on mobo, right?

    U can't hook up lcd to it, right?

    I only disconnected one card. Does the power required differ per card? I though they used the same amount of power.

    I don't have an HDMI, so I can't take out both video cards.

    Yes, but one could have a problem, so we need to eliminate the possibilities.
  27. BTW, do u have another gpu available?

    Or PSU for that matter.
  28. nikorr said:

    I will try that.
  29. Same as last time. It still crashed.
  30. Reubend said:

    Also, even if the RAM passes the test, it could be bad one. I've never seen it, but some guys swear by it.

    I would try to boot with 1 stick only and if still crashed, take the stick to another slot and another.

    Than 2nd stick and the same way try again and 3rd the same.

    It may boot on one and than we could find the source of the problem.

    What did u try, the GPU?
  32. BTW, did u played a lot?
  33. nikorr said:

    Yes, I tried the second GPU. And yes, I did game a lot.
  34. Reubend said:

    I am asking that, so u understand my thinking,

    PSU will last long time if u buy your PSU @ max Wattage + 150W extra @ 750W(900)PSU.

    It only last so long @ 750W. If u play a lot, it limits the lifetime as it gets hot for long time.

    It always has some Watts to spare, but not all brands do that.

    Now it could have less than u need.
  35. Are u trying the RAM now?

  36. I entered my specs into http://extreme.outervision.com/PSUEngine and it said that I only need 566 w (this was with 25% capacitor aging). I can try the RAM, but I don't think that's the problem if power is an issue, and I'm inclined to trust Memtest. I believe I still have a warranty on the 950 and the UD3R; should I try to replace either of those?

    Well, sure u can do that, but what if it is RAM and u will get new board and it will be still there?

    That's why troubleshooting at home beats the necessary time to get it troubleshoot.

    If it was my PC, that's what I would do. W7 is very particular about RAM, When XP will boot and start, the Win 7 still sometimes gives BSOD.

    When I got Asus board, the first time it didn't go through, unill I removed all 16GB and run only 1 stick and than added more it kept it error free.

    It is always good idea to get more opinions : )

    I get 558 w with that.

    Cool, did u try the RAM?

    Try to reset the BIOS with Battery out and dry start, than put bat back and so on ....
  41. I didn't try the RAM, but I made a lot of progress. I hit the clear CMOS button on the motherboard and found that I was able to use my keyboard (but still not my mouse) in startup repair and the Windows disk. Although it cannot repair the startup or do a system restore (it give errors with both), I think I am able to reinstall windows.
    My only question now is if it is possible for me to keep my data when I reinstall Windows. I think I will start a different thread for that because it's not very relevant to this one. Thank you for all of your help! :)
