Yesterday I updated the BIOs on my Intel DX58SO motherboard and the computer was running fine for about 10 min. Now when I turn the computer on, it looks like it is skipping the BIOs screen and logging into windows. However, the screen goes black after about 2 seconds of the windows login screen being on.

When I remove and replace the VGA adapter from my Video card (Radeon HD 6870) the screen flashes on briefly (for about 2 seconds) and then goes black once again.

I am trying to roll back my BIOs update with a USB flash drive but I cannot find a proper ISO file that will write to a USB stick. I have done nothing to the computer except update the BIOs, so I think that may be the problem.

Also I have tried moving the jumper and the battery. They do not seem to work.

Input would be greatly appreciated. Thank you.

OK, just to try, please take out the battery on your motherboard for 2 minutes, replace it and try again and let me know what happens –  Dave Rook Oct 30 '12 at 15:43
    
I've had CMOS batteries out for longer than 15 minutes by necessity. –  user3463 Oct 30 '12 at 15:46
    
Hey guys, thank you for all your help. It actually turned out to be my Vizio 26" monitor. Would anyone know how to troubleshoot this or is my monitor shot? –  Trent Franks Nov 1 '12 at 15:17
