This started after the laptop crashed during a heavy gaming session. Then on the windows 10 BSOD i held the power button and turned it off manually and it got stuck in a boot loop. I could click the power button and hear the two other fans start up before the laptop turned off and then turned itself on again. The screen was black the entire time it was boot looping and i couldn't hear the loud and noisy PSU fan once. I suspect dust may have clogged or blocked the PSU fan but would that cause the laptop to get stuck in a boot loop where the laptop turns on for maybe 5 seconds before crashing and rebooting all with a black screen?
