Default Need Help With Diagnosing System Fault

Right guys please help.

scenario:
My system has been frrezing randomly or more so when several activities are taking place on the system. If USB devices are added, the system freezes pretty quickly. The system would do this in excess of ten times a day.

What I done so far:
Opened the side of the system and stuck a desktop fan inside the case to eliminate overheating.

Result:
The system did not crash or freeze at all under normal use, however I did add two usb devices to the system and the system ran pretty well for sometime but then decided to freeze. Rebboted the system with the devices added and the system crashed straightaway.

Findings:
The system definately reacted positively to the extra cooling, however loading the system with devices made it instable.

MY question:
What components could be faulty?
What should I do next?

UPDATE:
The system also tends to want to freeze when I run the disk defragment tool.

would I be right in saying that the voltage values are just not right?

Your voltages are fine.

I don't think it's a heat problem but make sure the CPU fan dust free and check that the CPU heatsink is secure.

Run Memtest86+ and see what, if any, errors it gives.

Have you tried updating your BIOS?

With random intermittent faults such as these, especially freezing its probably your hard drive mate.
Get hiren 10.4 and do a hdd check by using the appropriate manufacturer. Do a quick scan first to see if this gives you an error (well fail message), if not try a long one before deciding.
