Unbelievable frustrating problem need ideas

After messing with PC's for many years I have come up against a problem I simply cant solve.

Started with random reboots. When it didn't reboot the mouse froze on the windows login screen. Tried a PS2 mouse and the reboots and mouse feezes remained. Upon reboot windows reported a GPU driver eror. Since then I have formatted, tried 2 USB and 1 PS2 mouse, new motherboard, tried the onboard GFX and a PCIe X800, tried a new PSU, new HDD. The only stuff I havn't tried is memory and CPU although the memory passes memtest+ 100% forever. This kinda leaves the CPU but the symptoms are not CPU related, in fact they tend not to boot if the CPU is faulty. One thing I did notice is a USB windows STOP error during setup but I restarted setup and windows loaded. Still the same problems, mouse freezes, reboots etc. So at this point I am lost. Totally baffled and ready to chuck the lot through the widow. Before I do does anyone have any suggestions? Help or ideas greatly appreciated.

Temps are fine and the system has been rock solid for over a year.
I always presumed memtest would pick up on any memory errors but it has to be CPU or Memory related. I will concentrate on those 2 for the time being.
I am sure most enthusiasts have been in this position at some time or other and its great that forums like these, even if the problem isn't solved, makes you feel so much better. A problem shared etc

Spec is:

Asus P5GD1-VM............Tried 2 motherboars
AOPEN case and PSU......Tried new PSU
2x512mb Corsair Value Select DDR1....currently swapping about
P4 3Ghz 530J I think.....not touched but running cool
Ati X800 and onboard 915G GFX...tried them both
XP SP2

The error when installing windows was right after copying the files across,first reboot I get a blue screen and a USBxxxxx something error. Bearing in mind this has happened on both boards? I now have windows running and am swapping ram about but neither USB mice will work. Very strange. Running a PS2 I know the next error will be when I install either GFX driver.

No USB modules running, just the standard ports on the back of the mobo.
SP2 was running great before.
With regards the HDD, as the chipset supports SATA I didn't think I needed drivers? Either way it was working for 12 months as it was.
Many thanks for the suggestions
