Windows 10: System Crash - Best way to restore Win11

My system running WIN11crashed due to a power hit. Relatively new machine with an ASUS ROG motherboard and a 1 TB solid state main drive with additional HDDs. Automatic repair cannot fix it. Ran SFC /Scannow and it says it found and repair errors on next boot, but nothing changes. Also ran CHKDSK with no noted errors. Went thru the various BOOTREC steps but I cannot run BOOTREC /FIXBOOT because of an "Access Denied" error.I have downloaded and created a USB WIN11 installation "disk".1 So is there a way to correct the "Access Denied" on the BOOTREC /FIXBOOT issue? Would this solve the issue?2

Is There a Way To Protect System Restore?

So I just got off trying to fix my dad's computer, for the 2nd time in a few months, because it has some kind of malware or trojan on it. The first thing I always go to to fix his system is system restore because he doesn't make many changes, if any at all, to windows, software, or basically anything system restore restores other than updating windows. But the last few times he's had various problems system restore, with either has it's restore points being deleted or restore won't even start up. So basically I really need help finding a way to either password protect system restore (preferably for free), get a 3rd restore program that won't get disabled by this malware crap, or any other alternative. I really appreciate any help you can give me because I've had this happen to a few computers that have come my way to fix and i wish there where a way to stop it.

Edit: Just found a program call Settings Lock (Settings Lock 2.7.0 (slarc.exe) Unix, Windows, Other Download) that I tested and it did successfully stop me from turning off system restore or changing it--but it's $25 and i'm not sure if restore could be turned off another other than my gui interface with that program so i'm still hoping to find something better or at least hear some more info about it.

 

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

 

How to delete inactive System Image Restore Points in System Restore

Windows 10 64-bit.
When I click "show more restore points" in System Restore I see a bunch of old "system image restore points" that were deleted in past and do not correspond to any currently active restore points. Clicking any of these old restore points, I simply get an error message saying they could not be found, and to select another restore point instead.I would like to delete these restore points listings but have been unable to do so.
So far, I have tried steps mentioned below without any luck :

Disk Cleanup through (C Properties
Disable System Protection (OFF and ON) in System Protection for OS (C
Disk Space Usage to minimum (slider button all the way to the left then 'Delete all restore points for this drive'),
Delete all shown Restore points in CCleaner (the problem ones do not show here),
Reset Windows Backup to Default in Windows 10 with 'Reset_Windows_Backup.bat' utility.

Any suggestions highly welcome.
