Saving BIOS settings causing system instability.

[Simon Slays]

Hi all,

 

I have had nothing but problems with my new PC since I built it. When I first booted up the PC I installed the latest BIOS for my X670E Hero motherboard which is 1415. I then installed Windows 11 Home and downloaded my latest Nvidia GPU drivers for the RTX 4090 and went into safe mode to remove old drivers with DDU and then installed the latest driver once I got back into Windows. After that I just installed all the software I like along with all of the drivers I needed from my motherboard manufacturer's website as well as some games. I have dealt with nothing but stutter in games which I found out was LightingService.exe from Armoury Crate so I closed that process and it stopped the stutters. I then thought my PC was all good until I went into the BIOS to enable EXPO and when I saved and exited, the system would do the spinning logo before booting into Windows, but the logo would constantly freeze and hang. When it finally would get to Windows which would take around 2 minutes I would try to login and the computer would then carry on freezing and sometimes BSOD. If I restarted my PC however, and tried to login, the PC would be completely normal even with the same BIOS settings. I would look at HWInfo64 and see that the RAM was indeed at 6000Mhz so EXPO was clearly working despite it freezing my PC until I restarted. Which makes me confused as to why it would BSOD or freeze one second and then the next it is completely fine. It's like no matter what I've saved in the BIOS it would cause the system to freeze on the initial boot until I restart the PC. Sometimes I couldn't even get to the restart button so I would have to use the power button on the case. I also had the PC change my wireless mouse's DPI when booting into Windows even though I didn't click the DPI button on the mouse.

 

I proceeded to start gaming and noticed that my CPU temps for my 7800X3D are far higher than most peoples that I have seen on Reddit and YouTube so I decided to remount my AIO coolers pump and apply some better thermal paste than what was pre-applied on my NZXT Kraken Elite 240. My temps were hovering around 50 to 60 degrees Celsius at idle, 70 to 80C when gaming and straight to 89C when using Cinebench R23 multi. Since re-pasting I had not got any decrease in temps and my PC was still unstable when changing any BIOS setting; even something that shouldn't hamper system stability such as changing AIO pump speed. 

 

Today I decided to reinstall Windows again and it managed to stop the freezing after saving BIOS settings and I can now load into Windows much faster, but now I have been greeted with another issue. After saving something in the BIOS and going into Windows, I no longer freeze but I do have much higher CPU temps, and in the task manager System Interrupts seems to constantly be utilizing CPU resources and constantly going between 0.1% all the way up to 27% usage even when I'm idle on the desktop. As soon as I restart my PC, the temps drop to something more reasonable and the maximum that I see System Interrupts go to is 1% or 2%. Right now as I'm typing this I am sat idle on the desktop and my 7800X3D is sat at 70C with System Interrupts constantly spiking.

 

I'm really losing my mind over this and would appreciate some help from anyone that might know what is causing my BIOS saves to ruin my PC stability and temps and some potential things I could do to try resolve the problem.

 

Thanks for reading.

TL;DR: I have high CPU usage from System Interrupts in task manager and abnormal temps after saving settings in the BIOS and booting into Windows and need help resolving this as it's driving me insane.

I've had the same exact issue, but with back 4 months ago, it happened even with stock settings everywhere:

CPU: Ryzen 5 7600
Motherboard: AsRock B650M PG Riptide

RAM: 32GB (2x16) Corsair Vengeance 5600 CL36

Did you solve the issue? At the time I returned the Motherboard and CPU and delayed my upgrade, but kept the RAM. Now I'm resuming the upgrade but am afraid the RAM could be the cause of the problem. I'm still waiting for all the new parts to arrive.

Same issue here. Solved by remove intel 760p.
