recently my computer will suddenly restart itself sometimes after 3hours sometimes after 6 hours of operating. i checked my cpu temp and is 51'c (amd) and the ventilation in my casing is very good as well.

does anyone know how to slove this?

thank you very much.

more effectively, change to Intel platforms

电脑自动重启的原因有很多，主要原因大多是电源供电不足或CPU风扇有问题。如果您的声卡是创新，特别是假冒的创新就更有这种情况。软、硬件上都比较彻底的解决方法就是：杀毒、重装系统、加风扇、换电源！

more,maybe ur os is not compatible with ur antivirus software.

For amd xp 2000+ 51 degree celsius is normal. But if your cpu is amd xp 1700+ and is still 51 degree celsius then there is something wrong.

i monitor the cpu temp and it fluctuate from 52 to 55
do u think is because of the cpu fan?
my cpu fan is original from amd

such problem
