Pc reboots when gaming.

[Engelbewaarder]

About 2 day ago I upgraded my pc from a 2070super + ryzen 5 3600x to a 4070 + ryzen 7 5800x3D. Everything seem to be working fine until some friends invited me to play fortnite.

I was 4/5 minutes in to a game, then my screen went black, al the lights on te pc stayed on and maybe 5/6 seconds later I am back at the windows in log screen, I log in and everything seems fine.

 

I tried soms things like putting the dx12 setting to dx11 and even on performance mode. I put the graphics setting al on low, but the same thing keeps happening.

 

I verified the game files, also nothing wrong there.

 

I tried to put heavy load on my CPU.

I tried putting heavy load on my GPU.

I played cyberpunk 2077 on ultra raytracing.

I played starfield on ultra setting.

These games play just fine.

 

I was thinking something is wrong with the PSU.

I got a corsair 650W PSU. Should be enough to power my pc. If it was faulty it would crash my pc on other heavy games to i would think.

My old 2070S used 2x8 pin connector.

My new 4070 uses only 1, i just used de old Y-splitter and only used 1 of the 8 pin end to power my new card. I could maybe try to use just a single 8 pin cable from PSU to GPU. But i don't believe thats te problem.

 

Anybody knows what else i could try ???

 

Spec.

Mobo:B450 tomahawk max

CPU: Ryzen 7 5800X3D

GPU: rtx 4070

PSU: corsair 650W

Memory: corsair 16GB 3200mhz ddr4

Screen: 1440P

Did you reset CMOS after swapping CPUs? It's possible BIOS keeps old memory settings and the DRAM did not retrain, causing instability in some cases.

Heyy thanks for your answer. It reminded me i did not update my bios.

Before it crashed every game.
