I'm working on this Dell Latitude D620 that runs like doo-doo. At first I thought it was malware or a rootkit or a ton of apps. I uninstalled everything. Ran full antimalware utils on it. Ran full antirootkit in Windows and from Linux live cds. Uninstalled free avast. Manually uninstalled remnants of Symantec endpoint protection. Thought memory was bad, removed each 1GB stick and tested. Same probs. (has 2GB total). Got sick of it so I put in another hard drive and loaded XP SP3 fresh and it STILL runs like doo-doo.
I am sitting here on a fresh installed laptop with all the windows updates installed and all of Dells updated drivers for this model and it is sitting here at 60-70% CPU Usage in the graph in the performance tab..
What doesn't add up is this:
under the "processes" tab, "System Idle Process" stays right around 65-75%. taskmgr around 15, explorer around 15-20 and 3-4 misc others each at 2-4%. If "System Idle" is running at 70% constantly wouldn't you expect the CPU usage on the performance tab to show a graph where CPU usage is around 30%? It's not! CPU usage is pegged at 60-70%!!
What is going on here?
