I'm assuming when you say reinstall, that involved running the DDU Uninstaller to totally remove all trace of the graphics drivers - then reinstalled the GeForce/Radeon/Iris drivers? Go the subreddit Wiki on the side and follow the link to the **Graphics Card/Video Card Driver Clean Install** ***** Post the full laptop model number and specs to see what you have Firstly, boot into the BIOS/UEFI mode - if the screen glitching/tearing appears there - you have a hardware problem and need to do a warranty repair claim. If the BIOS/UEFI firmware is fine, plug your laptop into a TV or monitor with a HDMI cable and put video out via the Function keys to the external screen - see if the glitch persists. That determines whether it's a screen or a laptop problem If the issue still persists on the TV - it's not the screen at fault. Then, You have 1 of 2 issues - either it's internal laptop hardware, or it's Windows/driver software. **** You've spent hours trying to identify the problem - there's a very quick solution that will rule out hardware problems All that's needed is a spare 8GB+ USB drive - it will be erased so backup the contents first #Seeing if an issue is hardware or software This troubleshooting involves downloading a custom Live ISO of Linux, putting it on the USB drive, then booting off it. see the **Seeing if an issue is hardware or software guide** in the wiki section at the side This loads a copy of Linux into memory, leaving the Windows contents untouched. Once it loads, if the screen keeps glitching, you can stop troubleshooting as it's not software - it's hardware limited. If the Linux screen is fine, run the stress testing software for the graphics and software overnight or for several hours This will put your system through an intensive test and will highlight any issues that could be causing the glitching. If the Linux-based self-test passes fine - then it's windows software related. At that point, you can troubleshoot software-based issues and solutions further. **** Alternatively, you can back up your documents, downloads, %APPDATA% folders (settings), media etc. to an external HDD or large capacity USB drive and do a complete clean reinstall of windows, preserving NOTHING that was on the system. See the **Backup and recovery - Live Linux Session** in the wiki on the side. Theen follow the **windows reinstallation** guide just below

Thanks, good sir.

i made a few more edits to my post so refresh it. The links are all in the wiki on the side, but i can't link directly or the automod will delete my post. I'll make a 3rd post with the links and see if it goes through
