I have a Gateway PC. I got it new about 1.5 years ago. Here are the specs:
Pentium 4 2.0 GHz
256 MB DDR RAM(DIMM)
Intel 82845G/GL Graphics Controller
Windows XP Home Edition
I just installed the nVidia GeForce4 MX 440 with 64 MB. Games are running smoother but when I play Unreal Tournament 2003, the screen goes black after about 20 minutes of playing. It then changes to lighter and lighter shades of gray. Then, it goes to the desktop and I have to maximize UT2003 again. Why does it do this and how can I fix it?
