hi i have no idea. so if u disable nv card and use integrated gpu problem would not occur?

You can strip out a lot of functionality that causes DPC latency issues and spikes with nvcleanstall, this is what I do

#

What driver version are you on?

#

Also full system specs. How did you do the clean driver installation, too. And finally, do you use a riser cable?

#

Have you tried using Display Driver Uninstaller in Safe Mode?

#

Also, since this only started happening recently, try a driver that predates Cyberpunk PL

#

Also, check your hard disk conditions. (CrystalDiskInfo for info + drive manufacturer's tools for testing)

#

Do you see any WHEA errors? (Have HWinfo64 sensors mode in the background and see if the very bottom of the list has something after the computer stalls)

#

What I'm telling you is to completely wipe your drivers (since driver rollback are not supposed without a clean uninstall) using DDU, and then install a driver that predates that game.

#

537.34 or earlier

#

If the stalls disappear, then try installing the newest drivers with the driver package you download directly from NVIDIA

#

No, just guessing if reverting to an older driver may be better as this isn't something you always had, but recently happening

#

And finally

#

Task Manager. Performance tab. Memory. What's the RAM speed?

#

And slot count

#

Stop all troubleshooting. Restart your PC. Enter BIOS. Enable XMP Profile 1. Restart. Check if freezes and stalls cease.

#

You may not have a "problem" but rather "lol slow default ram". Hope that's the case!

#

They tend to get reset every time the BIOS is reset. E.g. BIOS updates

#

Hmm

#

Can you do this extra step?

#

Load Optimized Defaults

#

Save and exit. THEN go to BIOS and load XMP

#

OK. Don't change anything in the BIOS now. This isn't a corporate PC, right?

#

(Or at least a corpo surplus)

#

You probably should turn off bit locker on a gaming PC as it's known to worsen storage performance since normally it's handled in software because hardware had backdoors

#

In This PC, are any of your drives have a padlock?

#

OK. For now, try the older drivers and see if the problem goes away.

#

And just turn on XMP (this shouldn't touch anything else)

#

I don't think TPMs get reset when the CMOS is cleared

#

But yeah, something definitely has degraded if it could XMP and now it can't

mystic hearth
#

Hmm.

#

So we have a system that may have hardware problems in the first place...

#

Can you try Profile 2? This is usually a slower XMP profile

#

If it doesn't boot, do the reset again.

Once that's sorted out, move on to check if older drivers work fine. Don't forget to DDU, as driver roll backs are not supported.
