Server CPU Usage at 100%
Right my Curriculm file server is running at 100% cpu usage!! it occasionally drops to 97% but then shoots back up to 100% again. I have run anti virus scans and anti spyware scans and found nothing, i have rebooted. What could be causing it? attached is a screenshot of task manager.
The server is Pentium 3 1.1ghz 1gb RAM. Its so old and i am currently looking at replacing it but i just want to get it back and working nicely in the mean time.

Is this a print server too? if so that can do it... it must be something like that as it is the "system" that is eating up the resources. Otherwise, any clues in the event log?

Process explorer can apprently be used to show what process is doing what precisely...might be of use?

Another vote for Process Explorer [ part of the Admin Bar - see below ] - may be worth doing a Hijackthis log too......... again on the Admin Bar.

Right the event viewer is showing over 200 identical errors every second! (screenshots attached).
I did have the mains trip in the server this morning due to bad weather but i switched it straight back on again as i was in there when it happened! The server didnt turn off as the ups kicked in ok.

I suggest a re-boot - specially after the mains trip like you stated - when its backup monitor the event viewer again.....and make a note of any other services that fail - [ a pop up will appear on the screen after it's booted if a service has failed ]
During the mains trip were there any scheduled tasks running ? Backup, AV scan ? etc......
Thinking about it, is there a UPS monitor service as you stated a mains trip - take a look and see if thats buggered up......

I have rebooted once just before i posted the first time. I am just doing windows updates then will reboot again.
Dont think there any task running at that time, the backup might still have been verifying but this run by another server. Nope there is no ups monitor service running.

A PIII 1.1Ghz!!!
*goes off to check what year this is*
P.S. What OS are you running again, and how many concurrent connections does it have? It may possibly be that the a service has given up the ghost. Try restarting the services one by one and seeign if that frees up the processor.

In your first screenshot it shows a proccess ''system.exe' using 82% CPU.
Except, there is no Windows proccess called system.exe. ( there's an account called system, yes, but no proccess!) My guess is a trojan, probably Backdoor W32.Spybot.OBB.
System.exe spreads by e-mail and via network shares, so get rid of it immediatly or your whole network/other servers will be at risk!
