Problem with computer freezing

[Almediwp]

So when I'm playing a game sometimes it will freeze and then the monitor I'm playing the game on will freeze and then the monitor says it has lost connection and I need to restart the computer by holding the power button. This has started after a power surge and I don't know if it is a graphics card problem or a power supply problem as I had to turn down the overclock on my card because it kept shutting off because of not enough power I'm guessing (psu was fine before to overclock and should be well enough to overclock more).

CPU Intel i7 4770k
GPU MSI Nvidia GTX 970
Powersupply is 650w gold rated rosswell
Motherboard is Gigabyte Z97X Gaming G1 Wifi-BK

You haven't stated your full system's specs. Please include your OS, boot(and storage) drives, ram and connected peripherals. Please be specific with them. It'd be a good idea if you could pass on the model for your Rosewill 650W unit.

1| Breadboard your system.
2| Borrow a PSU of similar wattage and reliability and test out your components with only the boot drive, GPU, motherboard, CPU and one stick of ram.
3| Repeat above test without a dedicated GPU.

Right about now, the scare you've gotten from that power surge should've warranted a battery backup/UPS for your system to prevent any further issues. From the way the thread reads out, I'm lead to believe you're on an installation of Windows 10. Have you tried reinstalling your OS?

Ok I'll be trying these tomorrow, I'm on windows 7 but I have tried reinstalling the os right after it happened.
