Every once in a while when i'm playing games or even sometimes playing videos in windows media player or burning a cd, the computer will freeze. the CPU temp is usually in the high 60s celcius when this happens, which i didn't think was hot enough to overheat the system. i'm also wondering why it gets that hot in the first place. here are my system's specs: - Athlon XP 1600+ - ASUS A7A 266 board - 256 MB DDR RAM - CPU fan with copper heat sink, 1 exhaust case fan - nvidia geforce2 32 MB video card - SB Live! 5.1 sound card - Altec Lansing 5.1 speakers total 90 watts - Seagate 40 GB HD - ATX mid-tower with 280 watt power supply - LG 16x10x40 CDRW the computer idles at about 58-60 C. when i take the side cover off that drops into the low 50s. but even sometimes when the cover's off it heats up enough to freeze everything when i'm running a program. i installed a case fan at the back, but that doesn't seem to be making much of a difference, at least to the idle temp. okay, questions: why does the system run so hot? should the system be able to handle those temperatures? could it be a power supply issue? would a, say, 400 watt power supply help? or the video card? it's a geforce2 and it doesn't have a fan - just a heat sink. i just moved the sound card down a slot to give the video card some more breathing room. when a computer overheats it normally shuts down, right? why is mine simply freezing? any other advice? thanks.
