I just bought a DELL XPS 410 its has 2.4 duo core 2gb and I just bought a GEFORCE 7900 GS OC and installed it and it seems to work fine altough when I play certain games my system will reboot and my modem will shut-off for no reason??? But normal procedures the PC runs fine. I tried downloading the brand new drivers but it messed my system b/c their is a chipset conflict and I had to restore everything! Can any help?? And if not can any tell what a comparable video card to the 7900 for around $150 would be that might work better? Thanks in advance!
