WHEA-Logger Event 17 - PCI Express Root Port

In response to my previous post about this problem below:

WHEA-Logger Event 17 - PCI Express Root Port - Microsoft Community

I think I have the solution, and it has to do with PCI-E Native Power Management in the BIOS (for Asus Z790 motherboards). The problem goes away if you turn it off, but I don't want to turn it off.

If you want it on without coming up with these errors:

Set your NVIDIA GPU in the NVIDIA control panel (if it's PCI-E 4.0 or higher, like the 30 or 40 series) to prefer maximum performance.

Change your power plan in Windows 11 to high performance.

It seems that the Windows 11 power plan of balanced mode doesn't work correctly with recent high-performance hardware like the ROG Maximus Z790 series and NVIDIA GPUs using PCI-E 4.0 or higher.

 

WHEA UNCORRECTABLE ERROR

Hi

I keep experiencing Whea Uncorrectable Error when ever i left my pc at idle or when ever i am browsing the internet. When ever i play games everything is just fine no blue screen at all. This all started after i upgraded my cpu and the cooler. This error
happens usually once or twice every day. The error occurred randomly, it can occur shortly after startup or after sometime of using the pc. I have tried reseat my cpu and cooler, took out my GPU and RAM and put them back on but the blue screen still happen.
