Hey guys i have a problem that the "geniuses" at overclock.net dont seem to have a clue about :D When im done playing a game or sometimes when i alt-tab out of a game, my system slows down a whole lot. I check and in my task manager (xp), "System" is showing CPU usage of 30-90%. I then used a process viewer and found out that whats causing the problem is the deferred procedure calls. They are spiking to, as i said, up to 90%. No program turns on or anything when it spikes up. It stays at these huge numbers too until i restart. Its not a virus or ad-ware or anything, anyone know what the problem is?
