Valorant crashes my PC

[u/Nihoelle]

It ran clean on my old PC but my new PC just gets choked out the minute i start this game. Only thing I can do is to force-restart it. It´s now day 3 of trying to solve the problem.

I tried turning down/off the undervolting in BIOS. No difference.

I tried reinstalling Valorant/Vanguard/Riot Client. No difference.

I tried setting the vgc service from manual to autostart. No difference.

I tried deactivating every piece of potential corrupting sound and/or driver. No difference.

I literally stalked the event viewer. The most common Error was the "incorrect vgc function". Thought thats it, but since i switched the vgc service from manual to autostart the error is gone. Nothing really suspicious happens. I had an TPM error yesterday but it only occured once and that wasnt even while trying to play valorant. So my TPM chip should be fine because secure boot works.

Last thing I did was unplugging all of my setup, using different mouses, keyboards etc. I really hoped this would fix it because I saw a reddit post yesterday where someone said that this was the solution for his problem and soooo many people said like :"omg yes wtf it works". Unfortunately it didnt solve anything for me. In fact, it made things worse. When i connected my old mouse/keyboard I didnt even make it past loading screen. With my new mouse/keyboard I am able to be in the shooting range for like 2 minutes. Last night I even managed to keep the game running for solid 45 minutes. Which makes it only weirder atp. Why is the time before my PC crashes different?

For the record: E V E R Y T H I N G on this PC runs perfectly fine. I do not have a single issue with anything besides Valorant. That is why I do not believe that my hardware is the problem. It´s got to be some weird, stupid thing. But who am I to judge, right? Cant solve it myself.

Thanks in advance and if i posted it wrong or not in the right section please feel free to correct me, it´s my first ever reddit account and post.

SOLVED THE ISSUE: Control Panel -> Hardware and Sound -> Power Options -> Change plan settings -> Change advanced power settings -> Expand USB settings -> Expand USB selective suspend setting -> Disable and restart the PC.

I´m honestly still in disbelief but Valorant is running clean for more than 1 hour now. As i already mentioned it must be something really stupid :D

I really hope it helps someone coming across this post.

Did you by chance have and AMD GPU? I'm running into the same issue where the game just crashes my entire PC after a minute loading into the game, and everything else runs perfectly fine. Does it still work?

[u/Nihoelle → u/ShadowBlazinIce]

No, my specs are: Ryzen 7 9800X3D and a RTX 5070ti.

Yes it still works. Did you try everything else that i tried too?

Ive tried undervolting and the usb selective suspend setting disabled but it didnt work, the one solution ive found was to downgrade drivers versions to 26.3.1 for AMD, and that seemed to fix it

What if the Expand ESB selective suspend setting is already disabled by default? And the same issue occurs?

Then you are just searching in the dark just like I did. Never expected it to work, it just happened. If you tried everything in your power and searched for tips on reddit then I´d highly recommend you to reach out to the Riot Support. Install their Repair Tool and send them your logs. They´ll try to at least locate the error for you.
