Mmm..... After further investigation methinks this could be expensive.
I removed the HD from my second comp and put it in the broken one and the samething happened, including CHKDSK and a handful of corrupt files. I thnk I may of caught sight of a desktop.ini file and the string $I30 kept appearing. Replaced HD in second comp and all well again.
I'm presuming that although the second comp had a different proc (2800+) and MB it should be stable in windows. It ran briefly and found all the new hardware but then rebooted and rebooted....etc.
I'm starting to think either the PSU, Proc or MB may be borked.
Anyway of checking these items, any ideas?
