hi guys, i am having a spot of bother with my pc and was wondering if you lot had any advice? my pc keeps just turning off but the power led and bluetooth dongle stay on. There is no pattern to this it just does it randomley. It was doing it a few months ago but it stopped and everything was ok and it came back with a vengeance! sometimes it wont get past the post screen at all and other times it takes 5-10 mins to go off but all the while all the leds are on and i can only turn off the power by flicking the switch on the psu??????? i would say it has done it 3 times for about a week at a time and was then fine for about 3 months! i just dont understand it at all hellllllp! i have done the usual spyware and virus scans and my temps are fine too.
