Hello, I am unsure of what to do and I would love some advice or assistance.

OS: Windows 7 64bit
CPU: AMD FX-4300 Quad-Core Processor 3.80 Ghz
Motherboard: MSI 760GM-P34(FX) (MS-7641)
RAM: Adata AD3U1600W4G11-B DDR3 U-DIMM 4GB 1600 (11)
GPU: NVIDIA GeForce GTX750-PHOC-1GD5
PSU: Apevia Turbolink Switching Power Supply Model: ATX-XG500W

Back in June, I had issues with my monitor going into power saving mode while I was gaming and I would have to forcefully shut it down. It would happen without warning, audio cutting out as well, and using SpeedFan showed me that nothing was overheating. Uninstalling and reinstalling drivers didn't help, results didn't change either when using it in another computer, dusting and cleaning the PC out, changing video settings, etc. I took it into a repair shop and they determined it was a gpu failure. I contacted ASUS Tech Support over several days and then sent my gpu to them after the issue wasn't solved and they just sent me another gpu.

I've had the new gpu for about a month and everything was great until yesterday where it started to have the same issue. It can't just be two graphics cards failing, surely...? I've thought about it being the PSU, as I can't really find any information about the model... I'm not tech savvy and I'm not really sure what to do right now. Does it seem like a power supply issue? Is the current gpu I have ruined?

I bought this prebuilt PC (CyberPowerPC Gamer Ultra Gaming PC (AMD FX-4300 / 1TB HDD / 8GB RAM/NVIDIA GeForce GT 610)-English) through Future Shop because I was on a budget and didn't know that this was a pretty disappointing build for an "ultra gaming" PC. I've had the PC since January of this year and I replaced the gpu it came with with the NVIDIA GeForce GTX 750 I got from newegg. If you think I need to update any parts, I'm open to any recommendations.

Any help is much appreciated.

Your PSU is very poor quality, and probably is causing this issue or even damaging GPU.
Your PSU is ratted as:
Tier Five
Avoid IMMEDIATELY. These units are highly unsafe to use. No such protections added, very thin gauge wiring used, false advertising and too much to list. Reference to a higher tiered unit for a better, money saving and a much safer unit. For your safety's sake, please don't order or pick one up for use in your system. These units are a potential fire hazard and could even kill you, let alone your system.
