Apoligies,I was thinking 24hr clock Doh, silly me 

OK, Sorted out my cold boot (sometimes),
Removed everything and the Cmos battery, jumper on the clear comos pins,
Done a low level format on the 320 gig  Hard drive,( took ages)
Cleaned the memory pins with a pencil rubber 

refitted everything, reinstalled xp, mobo drivers an all,
Seems Ok for the mo
