hello all- desperately need some advice on exactly how broken my computer is- after a week away it is failing to work under any circumstance. what happens is as follows 1- turn on pc, get screen saying CPU or overclock fail- F1 to continue, F10 to enter setup/ save changes 2- whichever of the 2 options I choose (F1 or F10) desktop loads ok- at first 3- when I try any application- e.g. web/windows explorer (or even just leave for a few minutes) I get a total freeze then the picture distorts so all text becomes illegible, usually alternating with black screen. Sometimes the black screen is constant. At this point it obviously becomes impossible to navigate and I have to turn off without shutting down. Any advice? Please tell me its fixable.
