I'm having a very interesting problem. I have a Intel P4 2.8GHz, 512RAM, PNY Vertigo Geforce4 Ti4400 card, Soyo Dragon Lite MB with SiS 360 AGP. When I run 3dMark2003 or Neverwinter Nights, on WinXP Home the benchmark or NWN freeze. I've got the latest drivers for video card, AGP, did all of the updates for XP. If I run 3dMark 2...it will freeze on the test called Nature. Its not a overheating issue, and only freezes on those tests and in NWN...so I'm wondering what could possibly be causing this problem??
