Does anyone know why my computer keeps crashing? It crashes when I play any 3D games (like Earth & Beyond, UT2k3), playing any videos (whether it's DVD, divx, rm, wmv), and in Microsoft office (doesn't matter which part i'm using whether it's word, excel, etc.). Funny thing is that when I'm browsing the web, it's fine, even with flash video, it seems ok. But the others I have listed above seems to crash my computer. Doesn't matter which version of Windows XP I use, whether it's Home or Pro, both will crash doing the same stuff, even with a little different setup. Does anyone know why this is happening? My system specs are as follows. -AMD Athlon 1.2Ghz -Asus A7V-133 Motherboard (Via base chipset) -832MB SDRAM -ATI Radeon All-in-Wonder video card -SoundBlaster Live -3COM NIC 905B -Sigma Design RealMagic Hollyplus MPEG decoder card -Adaptec 5100 USB 2.0 card -One other thing, all drivers are up-to-date.
