PC Crashes when playing video games such as dark souls 3, overwatch, DOOM, etc. Wanting to know if it's a hardware problem

[Reddercoats]

My computer is a rig I've built myself, and its been plugging along great. Unfortunately, it started to function weirdly and then crashed altogether, forcing me to reinstall windows. Everything is fine now, except for the fact that all of the video games I've been playing have crashed after 5-10 minutes, although sometimes they last for an hour. I'm pretty sure all of my drivers are updated, I know my video card and audio are, as well as my chipset.

As such, I don't think my issue is software, but it might be my hardware. I clean my PC every so often, and I'm leaning toward the idea that my PC isnt cool enough, my airflow isn't great.

My PC is not overclocked, but here are my specs. If anyone could give me any advice, it would be greatly appreciated.

OS: Windows 10 (x64) Home

Processor: Intel Core i5-4690K CPU @ 3.50GHz 3.50 GHz

Installed Memory (RAM): 16.00 GB

Video Card: Nvidia GeForce GTX 970

Motherboard: ASUS Z97-A

If I need to say anything else, please tell me.

Thanks!

What PSU do you have?

I fixed it by just unplugging and plugging back in all parts and cleaning out my computer. Easier than I thought it would end up being.
