Pci system error, with crash when in heavy gpu use

i had done some research about this topic, but i an new to linux and pc in general. google suggest to change pci=nommconf in /etc/default/grub. I not sure if this would work and i not sure what to delete or not.

GRUB_DEFAULT=saved
GRUB_TIMEOUT=5
GRUB_TIMEOUT_STYLE=hidden
GRUB_DISTRIBUTOR=“Manjaro”
GRUB_CMDLINE_LINUX_DEFAULT=“quiet apparmor=1 security=apparmor udev.log_priority=3”
GRUB_CMDLINE_LINUX=""

this the error i get

yes you need to add the kernel parameter to the gurb line:
navigate to /etc/default/grub and open the grub file and edit this line to look like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet apparmor=1 security=apparmor udev.log_priority=3 pci=nommconf"
then save the file and run this:
sudo update-grub
then reboot and check logs if you still have those messages

the error is gone, but i still having freezing when i got 2 applications open at the same time.

go through this link, and try the suggestions there… after adding the parameters, dont forget to update grub:
sudo update-grub
reboot and test

the warning error where actual error, my video card has problems with heavy loads, and temp, and it would shutdown.

Can you post some hardware information ? (mainboard, CPU, GPU).

i found the issue, i had pci extending cable, and it seen they when bad causing issues.
