I have a weird issue with my new X2...it's stable in SuperPi 32M and Orthos, and the RAM passes Memtest without a hitch, but I get this strange stuttering issue in normal use (i.e. Browsing the internet on Firefox). Every few minutes, my computer will just sort of "lock up" for a second or so, even if the system is not under load (i.e. when I click on a text box in a web page). While I'm gaming or encoding, however, the system never experiences this stuttering problem. I have no idea why this happens (and why it's only while the system is in everyday use, not under load) since I'm pretty sure my system is stable...I have also installed the AMD Dual Core Optimizer, appropriate AMD Dual Core Drivers, Updated BIOS, and updated CPU Drivers to ACPI Multiprocessor within Windows. I never got this stuttering with my overclocked 3500+ at 2.8 GHz, yet I get it with my X2 at 2.6 GHz...can anyone tell me why and give me some ideas to solve this major annoyance?
