I've been here working on this computer for the last 3 days & still cant seem to find the problem... The 1st problem I encountered was a black screen while getting ready to do a flight on my flight simulator where the entire computer froze. After restarting the computer I had lines on the monitor screen so I swapped monitors thinking that one was bad but had the same problem on the other. I then switched video cards, after a few attempts it worked for a while... I then started my flight simulator again and after 30 minutes it black screen again. I uninstalled the flight simulator and all it's components & did a fresh install. Without running the flight sim I still have the problem of the computer freezing and at times the monitor will not turn on.
I would like to do a system reset of windows vista but I never got the disk with this PC after it was built.. It's an Asus M3A76CM Motherboard. Any help at this point will be great.
