Hi guys, I'm trying to figure out whether it's my mobo or cpu thats dead. My pc has started to not turn on when i press the power button. I've unplugged all wires and tested the psu with a paperclip so i know that works. I unplugged the front panel, GPU and fans and left 1 stick of RAM in. Still no luck. I was told it could possibly be the CMOS battery but i replaced that too to no avail. So im currently stuck trying to figure out whether its my mobo or cpu not working. I dont have a mobo speaker so i was wondering, if i plug a fan into the mobo and attempted to power the mobo using a screwdriver to touch the 2 pwr pins, will the fans still run if the cpu doesnt work or isnt installed?
 
Solution
It could still be your PSU, paperclip method doesn't prove it's working properly but only that fan is starting. Only testing with appropriate tool can be full test.
