Graphics Artifacts How To Fix

[Conderoi]

I have been experiencing Graphics Artifacts for the past few months, I have no idea how to fix it/what is causing it. The computer had been working normally until I launched a game and randomly there was graphics artifacts stretching everywhere. My computer is a low end PC but I would still like to know if there are any possible solutions. Could it just need cleaning out?

Processor Intel(R) Pentium(R) D CPU 3.40GHz

EDIT: I was running the game a day before perfectly fine without an issue

Video Card AMD Radeon HD 5450

RAM 4.0 GB

Operating System Microsoft Windows 10 (build 14393), 32-bit

Most likely you need to clean your GPU. This can happen when dust builds up inside of the graphics card. You also might need to apply new thermal paste, if your temps are too high.

If you've done any overclocking, I'd suggest you undo it.
