Windows 10: Screen and pc glitch

I've been having this problem for the last four days where the screen suddenly becomes pixelated and it shakes around. I'm unable to do anything, nothing responds, except doing a manual shut down. It has happened several times today and I'm unsure how to resolve it as I'm not good with computers and I have noone to ask.

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??

 

glitching screen and glitching videos

Hello,

Recently my laptop screen started to freckle\glitch while playing videos either on the internet or on my laptop so I followed steps suggested as to uninstall and re-install the graphics update however, it happened again not so long after I did that (1 day later) and I fixed the display and so it stopped but the videos appear to be glitched? like I could see the RGB (there is a color stroke that appears ONLY while watching videos and I tried to take a screenshot and while trying to trim the photo I found it looking normal so it's only via videos

I'm using HP ENVY Laptop - DESKTOP -LUQEG7V

 

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)
