Unsuccessful Fixes to date since last June include a new mobo, new processor firmly seated, new primary hard drive, new memory, two clean re-installs of the WinXP OS. Drivers are up to date. The system is firewalled and virus protected. All the fans are spinning.
Questions:Forum posts suggest overheating. If the fans are running and the CPU is new, is overheating the likely issue? To test the overheating theory, I removed the case and have a small room fan blowing in air. So far, only one (disappointing) system freeze has occurred since the remedial breeze. If overheating IS the problem, and the fans are functioning, how best can I cool the PC?
Other posts suggest a failing Power Supply. I can replace the existing Hipro HP-D25737F3R 250W unit with the highly-rated FSP Blue Storm II 500W ATX PSU if the PSU is likely the problem. Can a failing PSU cause system freezes? Does a failing PSU contribute to overheating, or is the issue insufficient power to run the components?
Any other suggestions/leads will be most welcome. Very important: Can anything else cause the described system freezing behavior?
My setup: HP Pavilion AMD Athlon64 3200+, Salmon K8S-LA Mobo, 2GB PC3200 DDR-SDRAM, Samsung 160GB and Seagate 300GB HDDs, WINXP SP2.
