Hiya, With the help of a friend, I finished building a new computer this weekend. The problem is that the monitor just shuts down randomly about 2-10 minutes into playing any 3-d games. The monitor goes black, and in a couple of seconds, the green light next to the power switch starts flashing. This has happened in the exact same fashion for three unrelated games all of which are 3D based. So far, non-gaming computing (internet etc) is going fine. The monitor is recycled from my old computer, and it may be the problem: 1) The display driver is from 2001. It is a Gateway VX900, (SVGA) and the Windows XP driver update did not find anything newer. ANY ideas on safe/reliable sources of updated drivers? (Gateway.com was not forthcoming...) The specs of the new system: Windows XP operating system Home Edition Asus A8N-SLI motherboard Athalon AMD 64 3800+ CPU XFX nVIDIA SLI GeForce 6600 GT graphics card ***This is a DVI-out card, I had to use a DVI to VGA conversion plug to connect it to my monitor*** 2 Gig ram What else might you need to know?
