event ID 16 HAL
Input-Output Memory Management Unit
https://en.wikipedia.org/wiki/Input–output_memory_management_unit

Seems to tie into USB devices, especially Bluetooth mice - could be a conflict with wifi

seems to be linked to a bugcheck
Can you follow option one on the following link - here - and then do this step below: Small memory dumps - Have Windows Create a Small Memory Dump (Minidump) on BSOD - that creates a file in c windows/minidump after the next BSOD

  1. Open Windows File Explore
  2. Navigate to C:\Windows\Minidump
  3. Copy the mini-dump files out onto your Desktop
  4. Do not use Winzip, use the built in facility in Windows
  5. Select those files on your Desktop, right click them and choose 'Send to' - Compressed (zipped) folder
  6. Upload the zip file to the Cloud (OneDrive, DropBox . . . etc.)
  7. Then post a link here to the zip file, so we can take a look for you . . .

its possible

Try running DDU in safe mode and reinstall GPU drivers.

you mean it didn't fix it?

it probably means cause is hardware
Ryzen 5 5600X
Asus TUF Gaming B550 Gaming (Which BIOS?) appears to be dated 25th Feb 2022
24gb ram
1 x 16gb CMK16GX4M1Z3600C18
1 x 8gb CMK8GX4M1Z3600C18
GPU - GTX 1060
SSD - WD SN750 250gb

how long you used 2 sticks together?
what PSU do you have?

event id alone aren't enough to tell me anything. A lot of them aren't problems
I have found age doesn't really mean a lot when it comes to parts, they can die anytime from 0 to 10 years.

Prime will take a while so I would run it overnight.
if it finishes before you wake up, it will create a file called stress.txt in the folder its installed in.

Did you run DDU?

can you look in reliability history at the days it goes blank? it might show errors here.
I don't know if the freeze is the GPU drivers or the NVMe

what brand NVMe is it?

Yes I ran DDU and installed other driver but same issue,The nvme i use is wd blue sn570.One thing i request you is if the freezes are caused by processor side i would get a blue screen and my pc would completely be frozen but i can still here discord in-game sound etc,How can i test my nvme

whats the failed windows update?
got latest version of armory'?
no real signs there. the windows shutdowns probably result of you turning PC off to get picture back.
No sign its the gpu driver

41(63) happens after the restart, its a reaction to the shutdown. So you would need to look at events in the moments before it happens, as they probably relate to previous shutdown.

well, if monitor is just turning off but windows has no idea that its happening, then it is likely hardware.

Corsair VS650
VS appears to be bottom level of their PSU range - http://www.jongerow.com/Corsair_PSU_hierarchy/index.html
it could be PSU is turning monitor off.
It could be its turning screen off to make sure its got power to supply rest of PC. It can also shut off USB devices as well.

only 3 real tests for PSU
  1. the paper clip method - https://forums.tomshardware.com/threads/what-is-the-paperclip-method-of-testing-a-psu.1336402/ - but this is just to prove it works
  2. or multimeter - best way but most people don't have one.
  3. or in the BIOS to check the +3.3V, +5V, and +12V. - https://www.lifewire.com/power-supply-voltage-tolerances-2624583 - not very accurate as it doesn't show values at load
I would suggest getting PC looked at by a shop. Instead of guessing what part is to blame.

Has the problem happened today?

any extra USB devices?
any USB WIFI cards?
any speakers?
any old parts that have always worked fine before?

possible USB is tripping off screen, as the part of system that controls Graphics is also responsible for wifi and and USB. They can all mess with each other.

if windows isn't seeing a conflict it makes it hard to figure out cause. All we have is symptoms.
I would be tempted to just run with 16gb of ram and just see if it makes any difference.
