I've tried everything I can think of to fix the problem with no luck. A friend told me that this is the place with all the answers so here goes. I'm running an Athlon Tbird 900 on an Abit KT7A-Raid motherboard. My video card is the prophet II mx 64M, sound card is the SB Live. What I've tried thus far is upgrading my bios to the latest version, upgrading the via chipset drivers for my motherboard, installing the latest drivers for both video and sound card, dropping the apature size to 64M, and finally dropping to 2x agp. All this and I'm still crashing. Thanks in advance for ne help.
