I play many competitive games, such as CS:GO or Overwatch, and I also have an unreliable computer which overheats and shuts down and takes 5 minutes to turn it back on again. (salty reaction here) It hasn't been like this for a few months, but now the problem is back? How can I find out what's overheating and how can I solve it?

PC Specs:
RX 570 Strix 4GB (fairly new, installed into my prebuilt machine, no overclocks due to overheating issues)
AMD A10-7860K (came prebuilt, no overclocks due to overheating issues)
Unknown 16GB DDR3 RAM (came prebuilt)
GA-F2A88XM-D3HP Motherboard (came prebuilt)
Unknown CPU Coolers
Corsair CX750 PSU (fairly new, installed into prebuilt machine, added because of overheating issues, reccomended by tom's hardware peeps)

I can send a picture if needed.

So GPU is fine too. Regarding checking voltages, that's what HWinfo64 is for. Look at Screenshot #3 and look towards the bottom of the hardware readings for those three (your setup might be in different order):

^And make sure you keep that app open during a gaming session but shut down before the 5 minute crash threshold. Two or three minutes will suffice. Then exit the the game and open up the HWinfo app from the app tray as it should be running in the background the entire time.

What PSU do you have? Usually the PSU that comes in a pre-built computer is just strong enough to power whatever came originally in the pre-built. You add ANYTHING new, like a graphics card or more hard drives, and you can push it over the edge, causing it to heat up way beyond normal.

HWinfo64 specifically if you run a 64-bit OS (do not confuse that with CPUID's HWMonitor which is proven to not be accurate). The first thing I'd look at is the CPU. If it's getting too hot, then it could be thermal paste gone bad (it doesn't last more than a few years) or the mount getting loose over time, especially if you move the case around a lot.

This is assuming your case is not clogged/dusty and the intake/exhaust fans are working - and that your CPU cooler fan is working. This is also assuming it's not a PSU issue as noted above - cheap PSUs will throttle back on their power output above a certain temp, and the cheaper the PSU, the lower that temp threshold is.

I doubt it's your GPU but download MSI Afterburner and set a custom fan profile to make sure the fans are spinning up under load to a decent RPM. I had my 970s in SLI with an aggressive cooling temp-to-RPM speed % fan profile:

50C - 60%
55% - 75%
60C - 85%
65C - 90%

Ok. My PSU was added after adding the GPU, which was already overheating before, so I asked the forums here and they reccomended the Corsair 750M Bronze+. My fans aren't that dusty, and I bought the PC prebuilt without the new PSU and GPU in December 2016. My fans are spinning at a decent speed (85-90%) and have been.

UPDATE: checking hwinfo64, my cpu temps average 105+ degrees fahrenheit and motherboard averages 104+ degrees fahrenheit on minimal load (chrome open, discord, wallpaper engine, steam, antivirus)
I will check cpu temps while playing soon.

^^About 40C which is not unusual for basic use depending on your ambient temps (non gaming, not CPU intensive apps). Even though I'm in the US I prefer to use C vs. F when comparing temps as C is what most hardware review sites and forum members use.

Okay so you are not getting CPU thermal issues. Motherboard temps are not relevant. CPU and GPU temps are what to really watch for. Assuming your GPU temp is fine under load as well (did you check that?), then I'd lean towards the power supply. I don't see your internal temps causing the CX750 to go into power down mode. Sounds like you have decent airflow internally. So that can lead to a voltage supply problem. Look at these numbers in HWInfo64:

+12v
+5v
+3.3v

Specifically look at the Min / Avg / Max readings of each. If each are within the ATX standard tolerance +/-5% of each other in Min vs. Max then that's not an issue either. If they are within these specs:

+12c -> 11.4v to 12.6v
+5v -> 4.75v to 5.25v
+3.3v -> 3.135v to 3.465v

GPU 52C average with 55C max. And as for the voltages, where do I check?
