Take the 2-minute tour ×  Windows XP RAID 5 drives Intel Dual
Core processor 2 GB Ram  I am running a processor temperature
monitor. It does not appear to be overheating. I do not have
virus. The PC freezes and reboots. I do not think it is software
related, because it will reboot if it is doing nothing.  Could
it be the power supply? Might i need to replace it? How do I
diagnose this?  Is this the kind of question that is appropriate
here? I am not sure.  share|improve this question  migrated from
