PC Problem staying on if rebooted after being on for a long period

If I have my PC on for say 6-7hours and then shut it down normally. If I boot the PC up again in say 2-3 hours it loads into windows and then works for 15minutes before BSOD. If I say go to sleep for a night and then wake up the next day and boot it, it'll be fine. Any idea what part is causing this problem?

I recently changed my PSU/GPU due to problems with the old PSU. This was around 2-3weeks ago and there was initially no problem.

Apologies, I can never see it because pc auto restarts. Going to turn off that feature so I can note it.

Checked the Minidump using blue screen viewer: atikmdag.sys was apparently the cause.

code: KMODE_EXCEPTION_NOT_HANDLED 0x0000001e
