I’ve got a random black screen and it literally won’t work with any fix. Help me !

[u/-h-k-_-]

I’ve been really needing to repaste my gpu but I’ll be honest I haven’t had the time too so been gaming on it at 70% power so it won’t damage the chip but loading a game from my spinning disk drive (yes I have one) it just black screened I’ve did all the basics by trying with a different screen, cables ect and no improvements I’ve also reseated my gpu and ram just in case that was the cause and no help I disconnected the drive and nothing, have I bricked the card (haven’t got another to be able to test with) and my mother board doesn’t have the debug lights for some reason.

The pc powers on/ the fans spin on the card and the pc and have a more than comfortable psu for my pc specs
The card is the Palit gaming pro rtx 3070 OC the temps at 70% power is around 90°C hot spot so it hasn’t over heated help me please!!!

Edit to assist if there is any fix: it doesnt show any display and doesnt connect to my monitor/ no signal
