Let me first start by saying that I searched for other questions that matched my situation and I wasn't able to find any.
So, here's my issue:
Sometimes, when I turn on my desktop, it does not properly power on. I can see that the CPU warning light is on.
Other times, when I power on, the GPU warning light is on when my computer boots, and the screen does not work.
The way I remedy this is by opening up the desktop, flipping the switch on the power supply, and holding down the power button on the mobo until I hear the click of the power discharging. I then switch back on the PSU, wait a few seconds, and then hit the power button on the mobo. Sometimes this works, other times, it just causes the GPU problem to trigger and I have to start the process over again.
Here is the relevant equipment I'm using:
Motherboard: ASUS P8Z68-V PRO Motherboard
Video Cards: EVGA GeForce GTX 570 Superclocked 1280 MB x2 in SLI
So, is it my PSU, or might it be my MOBO?
