or maybe its my power supply hmmm every so often it goes off and won't go back on until after I plug it out for a few mins. this started happening a long time ago, and I changed the PSU since. It worked for a while, but then it started doing this again, like, it was going good for about a few weeks, usually it would now go off about once a day when I'm on it. So, is it a motherboard fault? Electrostatic bullshit? (There is no case cover for it - so I suspect this could be likely but I don't know the details of the effects) Maybe my power supply is bullshit and fucking with my PSUs? Oh also, more recently my sound card - which is on-board, stopped working. Entirely. My OS doesn't detect a sound card anymore (neither does Windows), so it must be borked, right? This computer is about 5 years old and my time with it has passed. But, it would still be good for my parents if I could sort this shit out. I'm guessing I should get a new mobo and cheap case, yush? Or, cheaper, a cheap sound card and a cheap case with the current mobo, or will that likely lead to more problems? Have I this all wrong and the current open case isn't so bad and the prob may be elsewhere? edit: oh yeah, heat might be the problem. Do you think? I'll post temperatures later.
