So far I've run CHKDSK, set pagefile to 0, defragged and then recreated it, and swapped out all the RAM with other RAM.
Crashed anything up to 6 times a day, randomly.
I wonder if it's something to do with Syncplicity? I'm not running volume shadowing (I have XP SP3 fully patched)
Typical crash report highlights:
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.

I can attach a minidump if that would help anyone.
