Possible Power Supply Failure?

System Specs

AsRock Z97 Anniversary Edition Motherboard
Intel G3258 Cpu
Msi Gtx 660ti
Eva 550 Watt psu 80 plus bronze
500 gb hdd
64 gb ssd boot drive

Windows 8.1 pro



Here lately I've been getting on my computer and everything was running perfectly fine until the other day when i got on and it started doing power surges. It would come on then shut off and repeat that over and over. Somehow or another when taking it apart and putting it back together now it will come on and shut off once, then stays on afterwards with no video signal detected on screen. I have tried the usual switching out the hdmi cable, taking the card out and trying just the onboard graphics and also a spare gpu, all with the same results. No signal detected by monitor.

Any help is appreciated, Thanks Eric

Dead GPU? try running off your iGPU which is off your motherboard. If that works it should be your GPU problems.

Can vouch for this. Bad GPU most-likely.

You should take everything out of your case and then slowly add parts to your mobo and see if it posts at all. You should start with the cpu then the ram and then the video card. I had the same problem and it was the gpu.
