I came back home to find my PC was on with black screens. I usually leave my PC on most of the time as my family members like to stream videos and stuff from it.
So I tried rebooting by holding in the power button and nothing happened. I decided a reset was necessary and even that made no difference. I can hear my PC actually rebooting as the fans stopped and restarted. I was very worried that my GPU may have failed on me. I live in Zambia and we have daily power cuts but my PC is connected to a APC Smart UPS so a power surge or under-voltage could not have caused this.
Removed my GPU and connected a monitor to my MB and still nothing. Nothing is displayed on the monitor/s even though the PC obviously starts up.
My PC specs:
MB: Asrock Z77 Extreme4
CPU: i5-3470 (not overclocked)
RAM: 2x8gb Corsair Vengeance 1600
Storage: 1)Kingston Hyper X 240gb SSD (OS installed on this) 2)WD Purple 1TB 3)WD Purple 1TB
GPU: PNY GTX 580 1.5gb
PSU: Thermaltake Smart SE 730w 80 Bronze
I removed all the power cables to the MB and re-seated them, nothing. Removed all SATA cables to the HDDs, nothing. Alternated removing the different ram modules, nothing.
On the MB I am getting the Dr Debug error code A2. I checked online and this guy had identical problems as mine: http://forums.tweaktown.com/asrock/51128-asrock-z77-error-code-a2-help.html
So tomorrow I will attempt swopping out my MB with another MB to see if it is the problem, which I suspect it to be. If that does not help I will borrow a PSU to see if it is the problem. However, I was hoping someone at Tom's could have a quick solution or think of something that I am missing. Hope to hear from someone AWESOME soon!

. So I added another PCIe power cable to connect to a different port on the PSU (modular). This seem to have done the trick. The GPU came back to life and my PC has been fixed. I do not know why it has been running just fine off the single rail on the PSU and suddenly stopped? However, it is fixed!
