Hi! i have a problem... i was playing my computer game (Call of Duty)... if u dont have it get it! and my computer just shut off! like BAM n it was off... so i dont no what to do Things ive done... Looked inside my case (no problems) poped out the CMOS battery and put it back in Checked my wall plug (working fine) Im thinking its my power supply but my power LED on my motherboard is on... So i dont no what to do... can anyone help

Was there actually a loud POP noise? I'm quite sure that's your power supply, you'll need a new one if there was an audible pop and your pc won't turn on. Try getting a good one, perhaps an Antec, they're more reliable than off-brand $19.99 ones. Make sure you can return it in case it doesn't fix the problem. midk

Yeah it sounds like your power supply. Just to be sure go into the adim tools and event viewer and look in system tab if you see an X look at the time and if the time took is dated around when your system shut off, then double click the event where the X is and click on the microsoft error link or copy the evenr error id and do a googler search on it.

Okay! for everyone who had my problem! it is my power supply! DONT USE OLD POWERSUPPLYS BECAUSE... I just got an old working on and put it in my computer i pressed my power button... nothing! then i switched the back safety switch on the power supply to on! BAM!!! static noices! sparks! and u can hear the motor die! I ALMOST DIED... i craped myself! There u have it! get a good one! no old one!

Did you buy an old one, or did you put in an old one you had laying around? That sounds bad. I felt about as scared when I literally RIPPED my P4 right out of its socket due to thermal paste. TWICE. midk

OMG! now guess what it went out!!!! I THINK ITS MY MOTHERBOARD!!!! everythign else is good but i think its my motherboard! GEEEEZ!
