I can play for a while and after about 30 mins i get video lag and the sound starts to studder i dont re installs and everything it started when i installed new gpu card and 8 more gigs of ram, but i find it hard to think thats the issue im leaning towards the mobo or the hdd but its driving me nuts. I hope someone has seen this beforee i read somewhere it has something to do with a windows 7 update. Please help
