Check your process tab and see which one is hog'en the CPU. You can also try shutting down the process one at time to find which one is the cause and if your using windowblinds and outlook express see if outlook is hanging the CPU as it will with a few windowblinds themes. Your log is clean!

Explorer.exe is running at 100%. Could it be a hardware issue? The system is only a year old. The memory is good. I ran memtest and there were no problems.

If my log is clean and my cpu is still running 100%, what can I do? I will start by shutting down the processes 1 at a time to see the effects.


Any further assistance is greatly appreciated,

Howdy!

I am going to move you over to the XP forum. I think they may have some answers for you.

My Mom has the exact same problem with her two month old Dell. Internet Explorer will take up 100% CPU usage and lock up the system. Anyone with any info on where to look and where to start, would be appreciated.

I've already run a virus scan, and ad-aware. They both come up clean.

Unlikely to be hardware..but I won't rule it out. Reboot into safe mode and open task mang and see if it's still uses 100% CPU. On the right side in task manager it lists Memory usage...how much RAM is it taking up? Have you tryed to turn off indexing for the HD?

There are a few causes of this as well..for example if your viewing an AVI file with DivX PLayer 5.2... explorer will max out at 100% even after the player is closed. Logitech keyboards have some driver issues which can cause the 100% cpu usage of explorer. Have a look here and see if this is of any help... https://support.microsoft.com/default...b;en-us;819946
