hello, recently, my computer that i have owned for about 3 years has been acting weird. sometimes, i cannot GET the pc to turn on right. when i press the POWER button, all i get is the light it shows on the power button.(not flashing) .. i also get a BLACK screen, and on top of that, a loud fan noise. i checked my computer for spyware using the program spyware DOCTOR. it removed all harmful programs but hours later, the computer crashed on its own. now i might know what is causing this but im not sure....sometimes when i'm playing pc games, it just freezes up so there is nothing i can do but hold the power button. i know i am not suppose to but i don't have a CHOICE. can that be the problem? please help me guys, i need you help. Overheating would be my first guess...
REMOVE a side panel and determine which is the offending fan...
If it's the PSU fan get a new PSU.i dont believe it is overheating. i cleaned all the fans out a while ago.. that was my recent problem. but now, when i restart the computer, i get a black screen. so im pretty sure it isn't overheating.Quote from: milkncheese on December 15, 2009, 09:44:38 PM

You have a failing fan in there somewhere...
