Computer starts with no post, takes up to one hour to start, shuts down randomly

This started yesterday when my computer just froze and completely shutdown and started again whilst i was on google chrome with osu open, it took up to one hour to start the computer and it didn't post at all, no display post or beap, when on the computer it isnt slow in any way and works fine, but it randomly shuts down.

SPECS
GPU: GTX 1050 ti
CPU: AMD-A8-6600K(I know it is a huge bottleneck)
PSU: EVGA 500W
Mobo: Not sure, some gigabyte one( can get the model if needed )

More about computer starts post takes hour start shuts randomly
  1. Could be related to power settings, like it's set to sleep or hibernate.
  2. I would make sure that cpu is compatible with that mobo. Whatever it is

    Had the computer for 3years now, it definitely is.
  4. Well when you get it going, I would get rid of chrome. It's the buggiest browser around

    If the cpu supports integrated gfx and if the mobo has video ports, remove the GPU and see if onboard works
  5. I had this same problem. I know this might sound stupid but it wasn't screwed firm enough so something was shorting it. Make sure there aren't any screws or wires directly on the motherboard. Make sure the wires supplying power to the motherboard are also in firmly. Overall i wouldn't replace anything until you are absolutely positive it is the problem.

    Removed the gpu and used the intergrated graphics yet the problem still persisted.

    Nope cleared all wires away from the motherboard, i did have the 8 pin cpu cable coming from behind the motherboard, but like i said i cleared it away a long with the rest from the motherboard and the problem persists.
  7. Almost 100% certain that the problem lies in heat, i un-overclocked my gpu and took my two side panels off of my case and my computer stayed up for 20 hours, then after putting the two side panels back on it lasted an hour, so i am gonna re-do the thermal paste and see if that helps.
  8. Might help to have some sort of monitoring software for logging temps.

    Under load with side panels off gpu runs at 50 and cpu at 60, its only when i put the side panels on the problem happens.
  10. I've re-done the thermal paste and fix the random shut downs, but the computer still takes 20-60mins to start and doesn't post
