last night my pc was running fine, i turned it off - and went to bed this morning woke up and the pc will load and after 30seconds or 1min it will turn itself off and wont come on again only if i press power button, all the hard seem to be working fine,

ive just got new ram, and the motherboard is not a cheap one and power supply is a powerful one.

im runnin a watercoolin kit on the CPU maybe there is not enough water gettin to the CPU :S

any ideas?
