[SOLVED] PC Crashing

[TRNaticus]

Hi, I've had a problem for a while now where my PC would just black screen then restart after I close a game, I've changed my Power Supply Unit as well as my GPU (Find specs below old and new). I've done a memory test and it's completly fine, cpu and gpu temps read normal too. I would really like to know what is causing this, thanks.

Old Specs

CPU: r5 3600
Mobo: Aorus b450 elite
GPU: rx 580 Sapphire 8gb
PSU: Corsair 400w
Ram: Corsair Vengence RGB 16gb (2x8) ddr4 3200mhz
Storage: WD 240gb m.2 SSD

New specs:
CPU: r5 3600
Mobo: Aorus b450 elite
GPU: RTX 3060
PSU: EVGA 600w
Ram: Corsair Vengence RGB 16gb (2x8) ddr4 3200mhz
Storage: WD 240gb m.2 SSD

So you went from an RX 580 to a RTX 3060, so Radeon to Nvidia. Did you use DDU to wipe your old graphics driver before installing the new driver?

No, I didn't know I had to do this, I will do this now (Thought I just uninstall old and install new). Would this affect my problem from happening on this GPU or is this a general thing I should do. Thanks.

It's considered best practice to use the DDU (Display Driver Uninstaller ) when you change GPU's, it should iron out any bugs and give you a clean sheet. Just familiarise yourself how to use it before trying.
