First question, is do you get video at any point, or is it just no video after Windows loads?
Second question is do you hear the usual POST beeps saying everything passed?
So I just installed a new cpu heatsink, and now I have no video. I have tried multiple cards in a few different slots and the onboard video. I flashed the bios and made sure the pc was set in its socket correctly. My computer turns on but I have no video on either of my monitors (I run 2 monitors)
I have a
asus m3n ht deluxe
amd 60000+ cpu
4 gb of ocz platnum ddr2
radeon hd 5850
nvidia 7800gtx (runs my second monitor)
winows 7 x64
