Here's what happened: I was using my computer as normal with no hardware issues. One day I booted it up and heard a long beep with 3 short beeps and no video. I checked the manual for my Asus P6T motherboard and this code means it doesn't recognize VGA. I have two Nvidia 9800 GTX in my computer, so I took one out and tried it in both PCI-E slots, then did the same with the other, and I get the same beep code. To be safe, I went down from 12 GB of RAM to 4 just in case. Same thing. This happened out of no where. No hardware changes, lots of air flow, no dust clogging anything up. Any suggestions would be greatly appreciated.
