I am using an AMD 1090t 6-core and sometimes experience lag. Here are two times I have seen and noticed it. 1) Uninstalling Windows Professional. I can feel the lag constantly while uninstalling, but AIDA/Everest says my CPU load is 8-12% depending on when I look. 2) While spreadsheeting using a program Rawr for World of Warcraft I experience lag as well. That could be the program though, but on their forums it seemed nobody else had this problem. Is there anything I can do to fix this? Thank you.
