on your desk top, hit cntrl, alt, delete to bring upi the windows task manager. Click on the "processes" tab at the top. In the lower left corner it will tell you how many processes you have running (lower the better, mid 20's for a clean system). To the right of that is CPU usage. On a clean system it should jump to 2% max at idle steady like a heartbeat with no programs running. If its going higher, you have to find what is grabbing the CPU. You can also get "ping plotter". Its a free program you can use to ping the servers at HTC and see how good your connection is. The address you ping is in the sticky at the top of the tech forum.
