New pc freezes

[belekiek]

Ok so I did a new build and for some time everything was fine. But now couple days ago I really had an opportunity to do some gaming. Played for couple hours all good. Next day blue screen and could not even enter win kmode_exeption_not_handled did a reset on pc came another error pfn_list_corrupt that I fix with ram timing I found on forum it worked. Windows was back in business. But once I started playing graphics was rubbish FPS was low and after some time freezing did some CPU stress tests same freezing temps I got once highest 74c. So I tried to do bios update and it got Frozen. I'm out of options

Ok so I did recover my BIOS and it's up to date. Now I tried to remove one ram and it worked perfectly. Did a stress test no problem. Now if I put ram stick in first slot I get a lid light on mb orange/yellow on Asus manual it's dram failure on second slot works perfectly. Does that mean my mb is faulty???
