Welcome To Computerhope

When was the last time your computer has been dusted internally? The issue most likely comes from high temperature on onboard graphics causing distorted, pixel tearing on certain demanding/intensive application or games.

i tried cleaning it from dust
i used speedfan and the system temperature while ingame was like 54
and does buying a new graphic card will help me in this ?

Let us try checking the overall temperature. Please run speccy after an hour of use or gaming or if no crashes happen eventually.

Download Speccy and then install the program.  To post and publish a snapshot of your PC.
. In the Menu bar, click File -> Publish Snapshot
. Click Yes > then Copy to Clipboard
. On your next reply, right-click on a empty space and click Paste on reply box then click Post.

 I presume that you were using the onboard graphics chip as only the motherboard was mentioned.
