I have internet cafe with 10pc.8GB kingston ram, 1TB Hdd, Asus motherboard, 2GB Ati HD 7790 graphics card. I was install pc all update, game etc. After i use acronis clone disk wizard apply one disk to other all pc disk cloning. Each computer all options apply(computer name, registry fix, chkdsk, ip etc)

For example many pc screen freezing(game running normally only 1-2 second freezing) when user playing Counter Strike 1.6 not directly after 20 - 30min.
1-2 pc screen flickering when user playing Call of duty 2 multiplayer after 30 - 40min screen sometimes everythings normally but generally i show this problems :(
I install latest graphics card driver clean. And i disable vertical refresh(always)

All computer scaning malware, updated latest driver(clean install), adwanced system care repair system etch chkdsk etc...
