Hi everyone. I'm hoping someone smarter than myself can help me figure out a problem that's been plaguing my PC for the last few months. The basics of it is that my PC powers down or restarts at what seems to be completely random occurrences. Sometimes it can be weeks without seeing it happen, other times it happens every few hours, and sometimes (like today) it happens every few seconds.
When it happens the machine shuts down instantly without going to a BSOD. Sometimes it will reboot and jump back into windows within seconds. Other times it will shut off completely and require me to manually power it back on.
The PC was a pre-build, but I have upgraded it a lot in the recent months in an attempt to fix the issue. Below are some of things I have done to attempt to fix this.
When the problem started I believed it was power related, so I upgraded the stock PSU to a Corsair 750w Gold. I redid all the cabling. I didn't see the problem for a few days - but then it started again.
After this I did a "reinstall of Windows 10". I didn't see the problem for about a week before it started.
Next I checked my temps with HWInfo and saw that my CPU was running at around 65-70 degrees celsius while gaming. I opened my case and realised that this pre-build only had 1 intake and 1 exhaust fan. I replaced my case with a Fractal Meshify S2, cleaned & dusted all of my components, replaced my CPU thermal paste and installed a Corsair H115i Pro . The most recent tests on my machine are giving me CPU temps of 42 degrees celsius playing the same game. After the cleaning and cooler installation I had no problems for two weeks, and in the last few days it has started again.
Other things I have done to try stop the problem are:
Any help would be greatly appreciated.

Other things I have done to try stop the problem are:
- Stopping all unnecessary software from launching at startup
- Running Windows memory diagnostics (it ran fine)
- Launching the BIOS and leaving it to see if reset occurs (it didn't)
- Launching software one at a time to see if it causes crashes (Steam, Epic, Chrome, Dischord, etc)
- Check the Event Viewer (not sure what I'm looking for here)
- Turn off "Automatic Restart" for hardware failure
