Zone Alarm, my free version, has a simple & easy firewall adjustment (two choices) for boosting gaming. When your finished gaming ZA automatically goes back into its normal mode. I usually do a regedit and eliminate any unneccessary links to a deleted game that reg cleaner would miss. Then do a fresh install. That works. Hope you have over 550 to 600 watts standard power supply. Anything under 450 watts to 300 watts will cause hiccups and some of your games to freeze/konk out or wont start at all. Next two years it could go over 800 to 1000 watts to gurantee playing games (demanding games only). lol Oh, I read Maximum PC and PC gamer magazines only and learned alot!!!
