I didn't change anything really. everything is like before. im just not playing cs go so far i will try it later and let you know if problem still occur. So you recomend me to buy new PSU ? or how can i test if GPU is right. Cause don't know what to do, when im only wathing series or just chatting on chrome its fine. i will check wifi / ethernet drivers but i think its fine too.
Are you playing other games with no issue?
Not telling you to upgrade your PSU, but you will probably want to, we've had lots of experiences with the VS causing instability at some point, and also taking out other components in cases where it completely dies. But all it is, is in sufficient power CAN cause TDR video failure.
You can use HWInfo to monitor voltages on your PSU rails. Namely the 12V, 5.5V, and 3.3V. Basically if you can force some testing you can find the MIN and MAX voltages of each rail, big fluctuations will be a sign of a defective PSU.
You can use
Furmark to stress test your GPU to see if the issue repeats
If you are only encountering an issue in one particular game, it becomes more difficult to pinpoint.
My understanding is D9 is the latest BIOS - 22/02/2016

It may be worth running
memtest to verify your RAM modules integrity, as this can cause TDR Video failures.
