Boot but no display

[Timbuh]

I just finished my PC upgrades and suddenly I have no video signal going out. The CPU fan works, I checked all the connectors to make sure everything is connected correctly, checked CPU pins, ram, and GPU to make sure they are all sat correctly and still nothing. The only thing I see the GPU doing is flashing little red lights above the two pcie ports when I turn the power off at the psu.

 

Old specs:

Ryzen 5500

Rtx 3060

12 gb ddr4

 

New specs:

Ryzen 7800x3d

Rx 7900 gre

32 gb ddr5

 

(Case and SSDs are the only things that stayed, psu was also swapped for a 750w)

I haven't done that, everyone I've asked said it'd be fine, how would I do that?

What? How exactly can a driver cause the PC not to boot? Besides, he can't get into win anyway lol

Have you upgraded the BIOS? Also, try resetting it with the CMOS battery. And maybe give a little time between resets to retrain.

I can definitely try both of those, I do the second thing with the bios flashback button right?
