Recently the leds on my motherboard shut off, and I the system will not turn on. I don't know if my power supply is fried or if my motherboard is fried. I would greatly appreciate any input on what I shoud do.

do you have the power tester that came with the PSU?

 

(a small 24-pin female connector that tests if power runs through)

CPU: Intel i5-2400 Mobo: ASUS Maximus IV Gene-Z RAM: 8GB G.Skill DDR3 1333MHz GPU: Sapphire R9 280x Tri-X Case Corsair Obsidian Series 350D PSU: EVGA 500w 80+ Certified

Can't test psu on a friend's computer?

 

If you can't you can try this -> http://aphnetworks.com/tutorials/psu_paperclip_trick or buy this -> http://www.performance-pcs.com/phobya-atx-bridging-plug-24-pin-black.html if u don't wanna try the paperclip method yourself. Connect any fan to psu molex and see if it runs.

 

No lights on mobo usually means a dead motherboard though.

As far as I know, most power supplies don't come with a power supply tester.

No need for those testers, just use the paperclip method to test the PSU...

Your right, I guess a paperclip could also work (thats what I did)
