My laptop started running sluggishly and freezing. The harddrive ended up being bad so i replaced it but the computer is still operating very slowly. In windows task manager the CPU usage graph sticks around 90-100% and the cooling fans are constantly running full blast. Specs: Pentium4M 2.00MHz, 640Mb ram (512+128)

Taskmanager can be configured to provide more information. From the top menu choose View>Select Columns.. If you select as one of your choices "CPU Time." clicking that column header 3 times will sort the processes according to the amount of time each has accessed the processor this session. System Idle is usually at the top, and that is as should be. Just below will be the main users of your resources. What are they?

System idle process is the part of cpu resources that is still available for use. It should be between 95-99 apptroximately when the computer is idling. Sorry for not explaining this beforehand. Please report what value system idle process is running on. If constantly below the figure I mentioned please list other processes which constantly run and take, say, over 20 percent.

Please download Everest (link below). Run it and go to Computer > Sensor. Wait few seconds until data shows up and report temperatures.

Ok, CPU temp is 46C and Harddrive is 40C. I think you are on to something as I've noticed the computer runs fine for about 10 min when you start it up but when the fans kick in they don't generally ever turn off.

Run Everest again and the same time run a full scan of your computer with your antivirus. kep looking at the temperatures every few minutes and report the maximum.

I still need cpu usage of processes as asked in my previous post.

In your first post you mentioned that the cpu grapgh sticks at around 100% and I still don't understand what caused that. Normally it should be around 2% when idling. If your computer runs antimalware programs upon startup then this is not idle. Like asked before let the computer finish all initial processes, including automatic scans and updates, and then check and tell me what system idle is.

Temperature of your cpu is rather high when loaded. This is not unusual and in fact is quite common among laptop. Please use compressed air (you can buy compressed air cans for computer uses) and blow clean the air inlets and the fan. Lift the computer up somewhat on two books to enable better air circulation. You may consider buying a cooling plate designed for this purpose.
