I Have had the same problem with my laptop in the past.... On updating to vista my cores would jump to 100% and stay the for hours and then maybe come down... if i was lucky.... This is a error with vista drivers if the hardware is incompatible with vista it will do this... its not spyware nor viruses its just vista... i havent came up with any fix for this yet
Start by looking at the services tab in Task Manager. See what programs are using the processor the most. Click on the CPU column to order the processes by amount of usage with the System Idle Process in the top or botton. Research the high usage processes and remove those that are not needed or look like they don't belong. Post back with the results.
The problem is that there is no process that is using that much processing power.Though the system idle process hovers around 0-1%,there is no process that takes up 90% or so of the processor.Also I have not connected the laptop to the internet in vista,which means there are no updates that are installed.
Are there any processes taking up more than a few percent of the CPU time?
In Task Manager add the CPU Time column (select View then Add Columns then CPU time) and see if after some time that something is active.
Did you reinstall Vista from the Dell partition of from the Vista disk? If from the Vista disk, you will need to install the system board drivers to get things working.
The fact that it works sometime is always difficult. When it is working, get on the internet and do all the updates. Don't do SP1 initially till you get the thing working.
Thanks KirkD for atleast trying to help me out with my problem.It seems like I have figured out what was the problem,my CPU Fan had gone bad due to overload and was running at a constant high speed because my processor used to heat up a lot.Called a Dell technician and he cleaned up the CPU cooling ducts etc and replaced the fan and my PC is as good as new! Vista is running smooth like butter,and I have installed all the important updates and Vista SP1. But I still couldnt figure out that how was I able to use my XP operating system under those pathetic conditions.Anyways thanks a lot.....
