Helo everyone, im new to this forum!
Yesterday I used the computer just fine, everything normal. But when I woke up today and powered on the computer it started rapidly powering on and off. The only way to make it stop was to turn off the power switch on the PSU itself. When I turn the PSU back on it starts doing the same thing non-stop, without me even touching the power button on the case. Normally my mouse LEDs stay on the entire time, even when the PC is off, but now they flash along with the rest of the system.
After some research I think that it can only be the fault of two components: the PSU or the MOBO.
My specs are:
Asrock H87 Pro4
i5 4570
Ballistic RAM 8GB 1600MHz
Saphire Tri-X R9 290x
Western Digital Blue 1TB 7200RPM
Kingston SSDNow 120GB
Coolermaster 750M
Any help would be highly apreciated!
Thanks in advance!

The only thing that is quite strange is that the whole night, like normal, my mouse LED stayed on, and was on intil I clicked the power button on the case... From that point it started flashing. For the LEDs to be on the entire night, the PSU had to be working.. How does it stop working over night, with just the click of a button...?

It just fixed itself in the day after... Now, ocasionly, it gives me a BSoD with the stop code 3b... Opening a new thread for it, thanks for the help anyway!
