so here is my new system: Gigabyte mobo with a Intel E8400 core duo 2 x 3.0 GHz 2 x 2 gigs of G.Skill DDR2 ram geforce 8800 GT factory overclocked to 700MHz also a somewhat older Antec 380 watt power supply: if that matters The problem I keep having is: after about 15 minutes of playing a game ,the system freezes and I am forced to do a hard restart. I've been watching the temperature on the video card, so I'm pretty sure it isn't overheating, nor do I think the CPU is overheating either. I worry that the power supply isn't big enough but the specs on the hardware seem well within range of power requirements... updated the mobo bios to newest version (steered clear of super new alpha version) and I've got the newest nvidia drivers that cover all the newer nvidia cards, something like 6600 through the new 200s. Out of everything in the case I'd say the ram feels the hottest, but it does have heat casing so maybe that's just the metal doing it's job. I also tried turning off Anti aliasing and whatnot, but no difference. Of most interest is that I played Exteel for about an hour and a half with no issues, while other more graphics intensive games all crash the exact same way. This leads me to believe it is some sort of software issue, but I cant think of what to do. I am at a loss, any ideas?
