Is there anyone who can help me? I have some P-III (800MHz - 1100MHz) PC. They were working fine till few days ago. Suddenly I saw it was hanging up during work and it was continuing in every 1-2 hours. But now it is hanging in every 5-10 mins. I formatted them and installed WinXP SP1 and SP2 and I also installed Win2000 in 1 PC. I am confused, is the problem from Hardware or Software?
