Having recently updated the Bios on my motherboard trying to fix an unrelated issue I am now plagued with some other kind of issue that only shows up when starting my computer.
Basically, when the issue is happening I get graphical stuttering in games (Very visible in Clicker Heroes) and the GPU test Furmark, every 4-5 seconds it will stutter and jump.
This problem only presents itself when I've turned on the computer from a cold boot and I can tell it's going to happen when the taskbar appears a more solid colour as shown in the first screenshot.
When the taskbar is looking like this, all the lagging graphical issues happen. When I restart the computer hopefully the taskbar loads in like this:
This is when there's no issues with the graphics lag at all.
I would really love some idea on what would be causing this issue and any tips on how to solve it.
