The short version:

Recently I bought my friend's 5600X PC (no GPU) and currently running my RTX 5070 FE in it, I tried launching Cyberpunk, but within 5-30 seconds, the screen goes black and the fans go full power. I have to force a shutdown through the power button on the case. I have also tried running DDU and reinstalling drivers but nothing. I genuinely have no idea what could cause this and any help or guidance would be appreciated, if you need more info and context I will write below.

The long version:

Before the issues began, I was running a i5 9400f with a Palit GamingPro RTX 3070 which worked fine. Around a week ago my friend sold me his 5600X machine, minus the GPU for a decent deal, so I took it as its better than what I had. It came with PSU, RAM, motherboard, case, etc. Once I had upgraded, the only parts I had taken over from my Intel PC was the GPU and storage, and I was running the same windows from my Intel machine.

Everything started really well, the first day as far as I remember had basically no issues. Notably I do remember installing Palit Thundermaster so that I could turn the RGB off (Which also has fan curve settings which is why I'm wondering if it has anything to do with what is going on). But then when I played some games (notably Cyberpunk) after some time, my screen would go black, and the fans would go to 100% speed (I think it even happened once in Valheim).

Two days ago, I left my PC on while I went downstairs for like 20 minutes, it was just on the desktop, nothing but Chrome and Steam open. When I went back upstairs I noticed that my computer was off, and would not turn back on, only two click sounds from the power supply, then nothing, not even the fans were spinning. After some troubleshooting I found that taking my 3070 out let the computer turn on again, and putting the 3070 back in my old PC also caused it to stop turning on. I had an old GTX 970 FE lying around, so i put it into my 5600X PC and it worked fine and didn't cause the same issue, so I assumed that the 3070 was just dying and was therefore causing these issues.

However once my RTX 5070 FE arrived today, after launching Cyberpunk for around 30 seconds, it did the same thing. Black screen, fans to full, have to force power off. It was very strange, the GPU was strangely silent for a bit, then the fans went to full speed, went to normal again, then it went to full and made the screens go black again. I kept an eye on the temps in task manager too, and it was acting strangely too, it kept jumping from 35, to around 71, and kept jumping between... I just have no idea what would be causing any of this, especially since the 970 was working absolutely fine until I got the 5070, which to me made it seem as though the 3070 was just dying.

If anyone can point me in the right direction let me know, I would greatly appreciate any help at all. I do have my old PSU from the intel system I was thinking of trying in the new machine just to see if its maybe the power supply or the cables that are causing the issue, though I am worried to keep testing in case the 5070 has the same fate as my 3070. If any more info would be helpful let me know, thanks for the help!
 
Hello, thanks for the response. Currenty as it stands:
R5 5600X
2x 16GB Crucial Ballistix 3200MHz DDR4
B550 AUROUS ELITE AX V2
RTX 5070 FE
PSU is a Corsair TX650M
I have 4 drives, 3 of which I moved from my old PC and the new one is a 1TB NVME which I've not activated yet.

I hope this helps, thank you for having a look. Any more info let me know!
 
Strange, on NVIDIA's website it recommends 650, and its only like a 30TDP higher than my 3070. Since my original query I have completely reinstalled Windows, and only installed the very essentials. I tried to launch Valheim (a 2GB game) and the fans go crazy just on the main menu, and temps reach around 71C. Closing the game made everything go back to normal. Thanks for the help so far, hope this additonal info makes the issue easier to diagnose :)
