Since it is something with the computer itself and not the OS, some things to try:
- Check for any motherboard status lights.
- Reseat your RAM.
- Run a memtest. Let it do a full pass, takes ~3 hours. If you see anything more than a single error, it’s the RAM.
- Reset your BIOS to factory settings.
- Update your BIOS.
- Reset your CMOS.
- As redxef said, unplug from the wall, hit the power button a few times to fully drain the system, then plug back in.
- Unplug everything you possibly can. Leave just a single monitor, a single stick of RAM, the cpu, and the power cable plugged in. Literally nothing else, not even a keyboard. (You will need to keep your graphics card plugged in as the 2700x doesn’t have onboard graphics)
- Swap to a different single stick of RAM and put it in a different slot.
- Visually inspect for any exploded or bulging capacitors.
- If you have gotten to here, swap in any spare parts you have from the prior list. Different graphics card, different ram stick, different monitor, different cpu or mobo if you have one.
- Unplug/replug your internal power cables, and unplug any unnecessary internal cables (fans, rgb, etc) (Is it this? Probably not, but we are getting to the desperate part of the list.)
- Reseat your CPU (don’t forget to clean off and re-apply thermal paste)
- Cry a little
The goal is to narrow down which piece of hardware is failing.
This is a good one too! And if you have a volt-meter, see if it’s low (or just replace it if you have a spare).
