Well, i just build my new computer, and now im starting to game... and when i do.. every 10 minutes atleast i freeze and im stuck in one spot.. and i cant do anything til it unfreezes.. alot of friends say i need a AMD Optimizer but when i install it, it gives me the 1721 error, they said i should rename or delete the Installshield but that doesnt work, and also been told Vista which im running comes with the Optimizer... but in game my game freezes... i have a Biostar mobo and running black edition AMD athlon 5000+ 2.6ghz with 2gb of ram... with a decent video card the Ati HD 2600 512mb.. any ideas
