Cheers! I have a problem. Sometimes my monitor just turns off by itself just like it went on standby but it didnt, or even worse it restarts by itself! By method of deduction I narrowed the problem to a graphics card. My configuration is: AMD Athlon XP 2500+, MBO ASUS a7v600-x, GeForce4 FX5200(256M), WD 80GB, Samsung monitor SyncMaster 793DF, im using audio card from motherboard . I changed the FX5200 with my old Ti4200 and it worked fine, but when i returned FX5200 it started to send monitor on "standby" again and again. Sometimes it takes 15 minutes to crash and sometimes 45. It doesn't crashes in all games. It crashes mostly in FPS like battlefield but it havent crashed in age of mythology. A few times the speakers produced a scratching noise and the picture on monitor was really mixed in colors. Little squares changed colors and positions on screen like it had some serious problem with graphics? Why is this happening? I tried to change some options for VGA card in BIOS but nothing helped with FX5200 while with Ti4200 it worked fine. Why?
