Windows 10: PC stops functioning when full screened

I built this PC earlier this year and it has been running beautifully up until this past weekend. Occasionally when full screened (occurred on Twitch, and Spectrum live tv) my PC stops responding to almost everything. The video freezes and I can minimize windows but cant bring them back to front. I can close programs, but the icon on the taskbar is still highlighted. I cant right click on the task bar. None of the buttons on the task bar work. Clicking on reset or shutdown "closes" all programs, and nothing more, among other issues.

Any idea what can be causing it? Any help would be greatly appreciated

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??

 

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

Blue screen and stop code

Hi
Jeferis,

There are a lot of factors for this matter to occur. To isolate the issue, we have some questions for you:

• 
  What activity have you done to
  trigger the NTFS and FAT FILE SYS loop?
  
• 
  were there any error messages?
  
• 
  What troubleshooting steps have you done so far?
  

It is possible that the
Boot
Sequence were corrupted by the previous activity which
triggered the Blue Screen Error and the loop. We recommend that you perform these
suggested troubleshooting
and see if there are any changes:

Startup Repair.


To access the
Startup Repair Screen, turn off the
PC 3-4 times(force shutdown),
while on the Blue screen Error. This will route you to the
Startup repair screen:

Advanced Boot Options > click Troubleshoot > Advanced options > Command Prompt

and run the following command:

Run SFC Scan:  

SFC
will
scan
and
run
an
automatic repair
to any
corrupted system files
that it will detect. We suggest that you perform it twice. To run an
SFC scan, follow these steps:  

• 
  Run
  Command Prompt as Administrator.  
  
• 
  Type
  sfc /scannow
  and hit
  Enter.   
  

Boot Record:

This will fix the corruptions on
boot records or boot
sequence. To run this command, follow these steps:

• 
  Run
  Command Prompt as Administrator.
  
• 
  Type the following command:  
  
  • 
    Bootrec /fixMBR  
    
  • 
    Bootrec /fixBoot
    
  • 
    Bootrec /rebuildBCD
    

Update us on how it goes.

Regards.
