I’m novice in Linux and start to use Fedora after friend advise, Yesterday I upgraded my PC to CPU: Intel Core i5-10600K (Graphic: Intel CometLake-S GT2 [UHD Graphics 630], MB: ASRock B560 Pro4, RAM: 32GB) and installed the Fedora release 33 (Thirty Three) with KDE Plasma 5.20.5. But after installed system booted I saw resolution only 800x600 instead of 1980x1024 (!!!) and Kde shows me notification about kernel error. I fully upgraded system (Kernel: 5.10.22-200.fc33.x86_64 x86_64) but resolution wasn’t improved and error was present.
The details of error are:
reason: mce: [Hardware Error]: Machine check events logged
backtrace: The kernel log indicates that hardware errors were detected.
The data was saved by kernel for processing by the mcelog tool.
However, neither /var/log/mcelog nor system log contain mcelog messages.
Most likely reason is that mcelog is not installed or not configured
to be started during boot.
Without this tool running, the binary data saved by kernel
is of limited usefulness.
(You can save this data anyway by running ‘cat </dev/mcelog >FILE’).
The recommended course of action is to install mcelog.
If another hardware error would occur, a user-readable description
of it will be saved in system log or /var/log/mcelog.

What can I do? Please help me, otherwise I will forced to refuse learning Linux and using one in general!!!
Sorry for my English. Best regards!!!
