Hello wonderful forum people I have a quite strange problem with my games which is sad because I really enjoy playing. I have read a lot of threads on similar subjects but unfortunatley not found any sollution to my problem. The computer I have a Epox 4PLA3I mb with a Celeron 2,4GHz processor and 2x256MB ram DDR 3200 from Kingston. My grapics card is a Gecube Radeon 9550GT. I run on 400W and I do not have any additional cooling but the fans that came with the case and processor. The problem The problem is that any 3d games (no need to make a list, any games except Civ 3 and solitaire) crashes randomly. The graphics just freezes while the sound keeps on playing and the only thing to do is to reset the computer. sometimes the game crashes after half an hour and sometimes after 5 minutes (always in propotion to the latest save it seems) With the ATI Catalyst I get an error message that the graphics accelerator has been reset and then I can continue playing untill it freezes the third time, Everytime It works three times! Then it says graphics hardware could not be reset please restart the computer. The troubleshooting I have tried quite a nuber of changes to fix this but nothing has worked. I tried changing the Graphics card to an old Hercules 64Mb, I tried changing the memory and run on either of the two 256 memories, I've tried a lot of different settings, AGP apperture size, AGP speed, Fast Write, DIMM voltage, AGP voltage. I have tried uppgrading all the drivers and the BIOS to the latest version, I have tried opening the case to see if overheating is the problem. I recently reformatted the HD and reinstalled WinXPpro with SP2 but that didn't help either. So what could possibly be the problem? I would be very happy if anyone could help me out on thisone because my next option would be to use the computer as a booy stone or something.
