Ive had this 'new' pc since early September and around the last week and a half its occasionally turned itself off, now the last few days it got more and more regular with it now being itl turn on for about 20 seconds max (wont even reach the windows desktop). An error message does appear just after the mother board screen saying CPU is too hot "press f1 to resume". Ive opened the case and turned it on to make sure the fan is working which it is and it still wont stay on. Any idea's on whats going on? any help appreciated!
