I recently put together a computer for myself. I've done this before so I have a pretty good understanding of how to do it. After putting everything together, I tried booting and I was able to navigate windows for a bit until I installed my 8800 drivers. After the drivers were installed the screen immediately went blank.
I tried restarting and then when I reached the Windows XP login screen for about ~30 seconds the screen went blank again and said "no signal." I initially thought it was because of the massive 8800GTS 640MB I had installed wasn't getting enough power. However, after switching that out for an older 256mb ATi video card, the same thing happened. The PSU I am using is 500w so I would think that would be plenty of power, but one thing the PSU does not have is a 8 pin 12v connection, only a 4 pin. Would that cause the problem I am experiencing? Could it be an overheating issue?
After swapping video cards back and forth, the computer won't even go into post now. I thought it might be the resolution the video is outputting is not recognizable to the display, but it displays the Windows XP login screen for about 30 seconds and then it will suddenly switch to no signal. If the resolution or graphics card drivers were the problem, wouldn't the login not display at all? Plus, the fact that the computer won't even go into post now seems to eliminate the resolution possibility. Also, my motherboard has a LCD bootup display and before when it would bootup, it would go through its cycle and stop on FF, which according to the manual means the system is booted. However, when the screen goes blank, I get a "- -" on the display, which makes me think the system has crashed as well, not just the video card.
Any help would be appreciated...thanks
