I have researched this topic to death and found there as many answere as there are posts about it. Seems everyone has a specific problem and a specific solution.

Unless I end task for explorer.exe my cpu usage is @ 100% and nothing else will run. Once I end task everything runs fine.

Where do I start????

Hi dadzilla , you can start by identifying the process(es) using up your CPU resources . Ctrl Alt + Del to call up Task Manager . Select the Processes tab and let us know what processes are at high CPU usage . As you have intimated there are a multitude of possibilities and google will throw up a million or more so the first step is to try and narrow things down to what's on your PC ...

When I pull up the task manager "explorer.exe" is generally running at 80% to 85% and "system" is using the remainder of processor to bring usage up to 100%.

Running XP Home Version

These are precautionary steps , I hasten to add . There's every possibility this is just a software issue but it's wise to determine the absence or presence of malware as early as possible .

I'm based in Ireland so will be here on and off over the next few hours while the other half of the world sleeps

I am running Norton AntiVirus and it is up to date and I run routine scans. Also running Adaware and Spybot S&D, both up to date and scans run regularly. Running automatic updates for windows so I should be good there also.

Norton is a huge resource hog, I would guess that is responsible

Get Process Explorer: http://technet.micro...s/bb896653.aspx, and see what sub-process(es) of explorer are eating up your CPU.
