Had my PC for about a year now. Recently it quit powering on. Installed a new power supply thinking that was the issue as the power supply I used (from a friend). After installing new power supply when I flip the switch on the back, I get a single flash from a single blue LED on the motherboard. At a loss here.
Build:
MSI X99a SLI plus
GTX 960
Corsair RM850 X
32gb Gskill Trident

How? Can you specify?

Also do you have some history on the computer behaviour before it start failing? Did you make any changes in the time before it start failing like this ?
It will do absolutely nothing. Nothing will come on whatsoever. I occasionally would have a crash when starting a game, after first start up. Other than that never had an issues. Did not make any changes.

Try bypassing the power button. If the motherboard has an on board button try that. Otherwise I just remove the Front Panel cable and use a screwdriver to bridge the power switch terminals.
I did try the power button on the motherboard. Nothing at all.
