CS GO crashes my pc

[vanguardstream]

I got this issue recently. It appears in competitive mode ONLY. I can play anything else alright, but when i go to competitive after 5-10 minutes it throws me a black screen with "no signal" and then i have to restart the whole computer. It is repetitive. I have put my settings on low, checked for driver updates, deleted cs go application and restored it with integrity check. Nothing has worked yet

Specs:

Windows 10
i5 4690k
Kingston HyperX 2x4gb 1866Mhz
Asus R9 290 DirectCUII
WD Blue Caviar 1TB 7200rpm

That's all the specs that should matter
