Suddenly very laggy PC - High CPU usage on idle

[ZeroStrikerX]

Last week my PC suddenly started to peform significantly worse than before. On idle my PC uses around 40% of my CPU (sometimes less and sometimes more). Games that use to play at 140fps are down to 30fps. Older games that use to run normally at a locked 60fps go lower and have stuttering issues. Starting ANY programs is very slow. Even music sounds like its stuttering from time to time. All didnt happen a week ago. Also on 1 game particularly (PUBG) i get a Blue Screen when launching the game. This happens consistently.

Blue Screen Stop Code: PAGE_FAULT_IN_NONPAGED_AREA

 

My system specs:

• Windows 11 Education N (Version 22H2)
• AMD Ryzen 9 5900X CPU
• 64GB Corsair Vengeance RGB Pro DDR4 @ 3200Mhz
• MSI MAG X570S Tomahawk MAX Wi-Fi motherboard
• MSI GeForce RTX 3080 Gaming Z Trio
• Seasonic Prime PX-1300 PSU
• NZXT Kraken Z73 CPU Cooler

Storage:

• 4TB Samsung 990 PRO NVMe SSD M.2 (Primary Boot Drive)
• 500GB Samsung 860 EVO SSD
• 2TB Samsung 870 EVO SSD
• 1TB Western Digital Blue SSD M.2
• 6TB Western Digital Ultrastar HDD

Display:

• LG UltraGear 38GL950G Curved 3840x1600 175hz

 

 

What i have tried:

• Reboot my PC (many times by now)
• Check and update all my drivers
• Check my UEFI settings for anything unusual
• Go to cmd and do a system file check (sfc)
• Go to cmd and do a disk check (chkdsk)
• Did a Windows Memory Check (no issues found)
• Full Windows Defender Scan (No issues found)
• Anti Malware Scan (No issues found)
• Test PC with just 1 RAM stick (4x for every stick)
• I used to have a Samsung 960 EVO SSD as my boot drive. And i thought that was the issues at it was very old but i migrated everything from that drive to my new 990 Pro and the issue is still here.
• Tried running on 2133Mhz with just 2 ram sticks and stress testing the CPU. All seem to work normally but issue remain
• Updated the bios to the latest version but issue remains

I've probably tried a few more things but over the span of the last week i cannot remember everything i tried. But the issues still persists. My guess its maybe an hardware issue with my RAM or CPU but i have those for just over a year now so they are still quite new components.

I'm quite handy with a PC and can normally fix almost all problems that i come across myself. But now I'm a bit out of options. If any of you need more information let me know!

Any help would be a blessing thank you in advance!

Was there anything you did in particular on your PC before the issues started to occur? I.e. downloads...heavy overclocking/stress testing etc. 

 

PAGE_FAULT_IN_NONPAGED_AREA is typically a RAM OC problem so try running at stock 2133MHz. Try running with 2 sticks (2nd and 4th slot away from CPU socket) and see if the issue persists.

I did try to upgrade my Windows 11 Education to Windows 11 Pro with a new Key i bought. Only to find out that one was for new Window installations so it didnt work on upgrades. But other than that nothing in particular. I tried running on 2133MHz and with 2 sticks. But sadly the issue remains.

That's pretty odd. Have you tried any CPU stress tests at 2133MHz and just two sticks? How are the CPU temperatures?

With "idle" do you mean just sitting in Windows watching that taskmanager?

40% CPU usage when idle is quite high, is there something special that's running in the background that you know of? Check taskmanager to see what is taking up that CPU usage. If it is a process called "System Interrupt" that's taking alot then there's a problem, could be a hardware error then.

I just tried a CPU benchmark. I've added the results in the image. The temps and speeds all seem fine to me.

When i start up task manager it does say 'system interrupt' for a few second but goes away after that. But in this screenshot all i have open is task manager, google chrome, 3d mark that just did a cpu benchmark and im in a discord call.

I don't see anything out of the ordinary here for a 5900X. Those temps look good and the CPU is boosting fine.

Yea, so i don't understand why game pc is so slow and laggy... Do you have any clue?

Motherboard BIOS fully up to date?

Just updated to the latest version. Issue remains.

If the other RAM sticks exhibit the same problem, then it can be an issue with the CPU IMC (integrated memory controller). However, Ryzen and Corsair Vengeance don't work nicely together so it could be that being the problem here but since you have ran with the setup for quite a while, I think it's an issue with the CPU IMC. 

 

The only other thing I can recommend would be to try and reinstall Windows (maybe on another drive that's laying around).

I did a torture test with Prime95 that also uses the ram to see if any issues could arrive. It found no problems. It did get a lot more warmer. To a max of 86 degrees Celcius. A friend of mine has some old ram i can use. So im gonna try that soon.

Definitely try the RAM out and see if you have any issues. 

 

Also, have you tried running memtest86?

I have discovered some new stuff. I tried using a different set of ram sticks from a friend. When i put those in the issue still remains. But today i started testing some other games to see what is 'playable'. When i was in the menu of Battlefield V i noticed in taskmanager that i was using 55GB of RAM. Like 80-85% of my 64GB of RAM. Which is very unusual as normally it doesnt use more than 25-35% while gaming. Then the fps counter i use in game (RivaTunerStatisticsServer). Showed that i use 0MB of VRAM. But in Task Manager it said 4,7GB. So its strange but i think the culprit is my GPU... Which i hope i dont need to replace since that was very expensive.

What do you think about this?

What else is using the RAM while this occurs??? Check with GPU-Z under the sensors tab to see how much VRAM the graphics card is using while gaming.

I looked incorrectly. There was a different program that has a (known) memory leak so it used about 50GB of RAM. I have removed it now but was not the source of the problem. So far i see nothing unusual on GPU-Z while gaming. But still have lag/low fps and a lot of stutters.

I am gonna take my GPU to a friend and try it in his PC to see if its a hardware issue with my GPU. Also gonna do a clean Windows install later this week.

@CommanderAlex i have fixed it. A clean Windows installation did it. FINALLY. Im still not sure what the cause was but im happy to be able to do everything again on my pc. Thanks for your help and support!
