Question Left the PC for 10 minutes, came back to find "No Signal" on black screen ?

Hi everyone,

As in the title, I left the PC for 10 minutes, came back to black screen - no signal coming from GPU. Plugging into the mobo works, so clearly a GPU issue. Cooling has never been an issue, I use a Raijintek Morpheus 8057 heatsink with noctua fans. I can't see why it would suddenly break out of the blue...
So far I have:

• Reseated the GPU
• Restarted using the other display port slot
• Uninstalled Graphics drivers
• Updated windows

Specs:
Intel I7-9700k @5.1
Evga 2080
Asus ROG STRIX Z390-I
Corsair LPX (2x8GB) DDR4-3200
WD Black SN850 2TB M.2 (system)
WD Black 500GB M.2
Corsair SF 600 W 80+ Gold

Thanks in advance, any input is greatly appriciated!

Have you checked the power supply as for me that is what conks out first.
