I recently downloaded DirectX upgrade. But the system was slow before that.
I installed a new driver for my HP Officejet K80 printer, from the HP website. But I think it was running OK after that.
No new hardware
No weird websites
It appears only to slow down when I run IE

The CPU usage flucuates between 5% and 100%.
The "processes" tab shows about 45 - 50 items running, the largest being CCPROXY.exe SYSTEM at 118,820


Thank you
