Custom PC works fine then boot loops

So I built a custom pc recently and it would boot loop when it wasn't completely level. After figuring that out I kept it on level ground and it worked for a few hours before turning off randomly and restarting. On restart it worked fine for about 20 hours and then it shut off again. This time, even on level ground, it was stuck in a boot loop.
I fixed the power problem but now it's boot looping after about 30 minutes of running fine. Then the monitor lost signal but the computer was still on and working. I powered off the pc and powered it back on and now I'm stuck in boot loop again, any suggestions?

perhaps your GPU and/or cpu heat sink is severely sagging due to size/weight?? Or perhaps a standoff or screw is rolling around behind the mainboard? That's tough one!

Something is severely wrong for a tower to 'care' if it is level or not...

I'd be checking your temps within the BIOS carefully as well...maybe the heatsink is not correctly mounted?
