Please list all system specs.

Have you checked CPU temps?

Did you reinstall Windows when you built your system?

i didn't reinstall windows when i rebuild my pc, although it has worked fine for over a year, it's only recently the problem began. the GPU is my newest addition since i've had that for approx 2 months now - although again it worked fine up until now

Any expert will tell you that you need to do a clean install of Windows when you change to a different motherboard on a system. You cannot rule out any of your issues until you have done that. It's quite normal that it will seemingly work fine for some time without a clean install, but it usually surfaces sooner or later in the form of unusual or under-performance.

Have you checked your temperatures to see whether anything might be overheating? And what kind of CPU cooler do you have? All-in-one water coolers can fail, at which point your CPU will throttle to keep temperatures within limits.

I always monitor my temperature when gaming, i've never had any problems with temperature, and i've double checked after the problem began. both CPU and GPU temperatures rarely go over 60 degrees C - even in gaming.
i have this cooler - Cooler Master Hyper 212X (EU ver.)

Is it enough to do that with Windows' own clean install option, or do i have to wipe everything and then install windows manually?

silly question. where did you plug your HDMI/ DP ?

i understand your question, the symptons surely applies that i'm using the onboard GPU, but i have the HDMI plugged to the graphics card.

The Problem is somewhat resolved, I have been diagnosed with a faulty GPU from my local PC supporter.

thanks for the help and answers. you're the real heroes.
