system keeps turning off....!!!

my system has all of a sudden started playing up.... for some reason it just keeps turning off... it happens at random points... could be during boot up or it could be once it has been running for 15 minutes or so...

i have good connections all round and have changed nothing on my PC, it just seems to have started out of the blue!

any ideas or suggestions would be greatly received.

am watching temps in bios now....getting 70 degrees within five minutes- fan running at over 2000rpm.

that seems warm to me. for just running the bios... has to be the answer. or not.... will have to get my another fan to check it.....
