(*do not disable anything in here other than something that you know is an application you installed, should you look in there)
-Graphics drivers. Remember the last time they were updated, if ever at all? Do you know what handles the graphics (GPU)?
-Background applications. Consider what else the system is doing, look at msconfig 'startup' tab, and Processes under Task Manager
-Firewall/anti-virus. Several such applications are guilty of checking on games every few minutes as opposed to when it is launched, hogging system resources. There may be an option to add the game's .exe to an exception list.
