Cpu Usage At 100% In Task Manager!

Hello Friends,

I had only Two applications running on my system,but whenever I check for the Task Manager CPU usage it shows 100% usage, which is strange according to me what may be the problem, is there any other services which I could not see...

Please let me know,This increases my curiosity

Thanks for your help...

Try the following, but try them in the order posted one at a time. If the first suggestion does resolve the problem, then there is no need to try the next two.

0. Go to Start/Run and type:
regsvr32 C:\windows\system32\zipfldr.dll /u and click OK.

1. Disable "Automatically search for network printers and folders?":
2. Folder Options >> View >> "automatically search for network printers and folders".
   
3. Delete index.dat (it may be corrupted). You can find the file via Documents and Settings/(User)/Application Data/Microsoft/Internet Explorer/UserData/ folder, if it is not found there, search your computer and delete the file then reboot the PC.

You should see which task is grabbing all the cpu.

here are a couple of things to try

1. Try logging on to the machine as another user. See if the problem is tied to one user only.
   
2. Take a look at the graph in task manager(the performance tab). See if it is totally pegged at 100 or if it's jumping up and down.
   
3. Take a look at the networking tab in task manager to see if you are using the network or not. Usually this is under .5
   
4. If something is grabbing all the cpu and not showing in the task manger, it might be a virus. in addition to the other tools you use, see if you can get a copy of rootkit revealer and see if anything shows up there.
   
5. I've found that on my machine, some websites will cause IE to go crazy. I simply kill the internet explorer process (which closes all IE windoze) and I'm good for a while.
   
6. Try to think if you added any hardware or software about the time you found the problem.

Hope this helps a little.
