I was getting some system/graphics problems in game yesterday (Arma 2) so I decided to power down the machine and dust out heatsinks in case there were heat issues. After I took the heatsinks out, dusted them, and put them back in, the system wouldn't display anything on the monitor. The bios was giving me 1 long, 2 short beeps indicating a display adapter error at start up. I tried replacing my vid cards with one of my roommates and the same thing happens. Don't what the problem is cause I know that his video cards are functioning properly.
My specs are:
Asus L1N64-SLI WS
2x 3.0ghz Athlon 64FX Socket F (thats two seperate processors)
4GB Corsair XMS RAM
2x GF8800GTX 768MB SLI
Windows Vista Ultimate
For the record playing Arma2 has crashed my system from time to time. Never had a problem this bad.
