Ok...
 

Well I know I've made posts before about my computer randomly turning off or doing whatever, well here we go again...

Apperntly my PC locked up last night, I don't know why. Now every so often it either locks up or goes blackscreen on me. Doesn't matter what I'm doing it just does it. Now the strange thing is it will do this for a little while and then work fine for days/week/months, because it's done this before. Again nothing has changed, I didn't do anything to my computer.

sounds like something internal might have gotten fried...whats running when it usually does this, doesnt have to be a particular program, but something(s) that might drain on the CPU alot.

EDIT: got what i needed for specs and stuff. looking at one of your old posts on this same thing 105 is pretty warm i try not to let mine get too much above 90F, right now its at 86F. id take the side panel off, blow any dust out of it and leave the side panel off for a while if you can. if this "stops" it then we have found our problem
