White Lines Flickering

[Fleskhjerta]

Hi,

Since today, when i load a game or when i use my CPU a lot, there's some white lines flickering on my screen.
They are like 1 pixel height, 200 pixels long, and are only in the right of my screen.

Here are my specs in case you want to know :

AMD Athlon II X3 @ 3.00 Ghz
AMD Readon HD 5450 with 2.7 GB of dedicated memory.
4 GB of RAM
Microsoft 7 64 Bits
And my screen is 1920x1080 HP S2231a

Overheating? Check temps

to check you temps (like dj said) get CPUID HWMonitor and take a screenshot of the cpu/gpu temps.
Also i would try using a diff. gpu, even integrated to see if you get the same issue, cause lines on the screen usually mean gpu
