Just today I installed windows 7 on one of my older machines. The problem is that I get really crappy performance and 100% usage.... kind of. Let me clarify. When I first start up the computer I can surf the web, listen to music and even do some light gaming with no problems, and the performance is quite snappy. But, if I try to open the control panel, or view the system specs, or change my home group or anything like that I get problems. First, the window will take forever to open and run the CPU up to 100%, and when the window opens it will still be maxed out. If I open Task Manager all the processes will read 0% even though the manager itself reds 100% usage. My system has a 3.4 Ghz P4 with 2 Gigs of RAM. It had Vista previously (Bleh) and ran it quite well. Any ideas? Oops, almost forgot. I'm running Windows 7 Ult. 32 bit.
