Hi One of the things which prompted my recent 'Another new computer!' thread, was my current pc going bonkers for no good reason. I might wait a few months for the upgrade and in the mean time would like to play games still, so was hoping for some help with the problem ..... Yesterday the pc just started crashing about 30 seconds into any online game of quake3. The screen just suddenly freezes within q3 and I get this horrible 'stuck record' kind of noise screeching out my headphones. Ctrl-Alt-Del, Alt-Enter (q3 doesn't like alt-tab) or any other combination of key strokes, etc will not do anything. It appears to me that the whole pc has crashed. My only option at this point is to reset the pc. I'm pretty sure it can't be q3, as it's been installed and played for years, with no recent changes made to it, other than updating punkbuster at the evenbalance.com webby. It seemed to let me play offline single player ok last night, but maybe I was just lucky. It crashed on baseq3, osp and 3w servers, but seemed ok in ra3. Iirc the others all use pb but ra3 doesn't? Could it be pb maybe? Anyone had problems with it also? I tried CoD and this played ok for a few hours, then it crashed and brought up the microsoft error reporting thingy. CoD has been known to do this in the past, but hadn't done so for a long time, so I don't know if this is related or not. I checked the cpu temperature in the bios and it said 60 oC. Dunno if that's good or bad tbh and I'm not certain whether I can tell the temperature of the gfx card. I do have mbm5, but haven't had it on when the problem has occurred, as yet. The pc has been slowly getting really sluggish over the last year tbh. PC is a Athlon 2400xp, GF4 ti 4800se, latest certified nvidia drivers, 512mb 2100ddr ram, winxp. Only thing odd I noticed was that after the crashes, the monitor refresh rate had changed from the usual 85hz, to other things, including 60hz and 72hz. Weird! Any advice would be greatly appreciated.
