As the title says, I just got done installing 7 64bit (after like a 5 hour install) and now the OS is slow to respond to anything I request of it. XP ran perfectly on this rig My specs: Harddrive: WD Caviar Blue Sound: Creative Sound Blaster X-Fi XtremeMusc 7.1 CPU: Pentium D 940 Presler 3.2GHz RAM: Kingston 1GB x4 Video: Dual XFX 7950 GT PSU: Asus Atlas A-55GA 550W It was a clean install on a brand new hard drive. Needless to day after the horrible install time this annoys me to no end. Upon checknig in the Task Manager, the entire time I have the machine running the CPU is under 100% load. I, however, cannot find out what is using it. Task Manager was using 39% and nothing else was above 1%.
