Every time i load up any games on my PC I will get o's and x's all over the screen and eventually it will just freeze up with no sound to where i have to manually power it down. I bought a HP Omen Obelisk from bestbuy only a month old, I'm 99 perecent sure it's the graphics card doing it. All drivers are updated. Link of what it looks like when it does it.
