I have been noticing weird artifacts in Windows whenever viewing any images or even in my desktop background as shown below. They are prevalent more when the CPU is overclocked but nowadays even on stock speeds although the amount of artifacts is less on CPU stock speed.

- Checked RAM & passed memtest.
- Replaced motherboard as well as PSU.
- Tested by removing gfx card & running on integrated gfx but they still show up.
