Every time I play a big game like GTA 5 my computer just cuts out. When I'm on Garry's Mod it's fine, but also some small games cut out, e.g. Sneak Thief. I have had this problem for about 6 months now and I have literally tried everything. Re-setting my PC, to many more things and I just don't know what it is. CS:GO has been working fine now for a couple of weeks but today when I got shadowplay and using it on cs:go, it just cut out again. Help?
