Ubuntu always running 100% processor load

[Bopher]

Ok. So I had a nasty virus on my file server so I decided to change over to Ubuntu with Samba to share with my other machines. Now I've noticed my processor now is running 100%. I the server is headless so I've been using TightVNC viewer to view the desktop and I pulled the system monitor and the processor is running 100% all the time. All the computer is doing is sitting there holding pictures from the past year. No other services yet on this, i.e ftp, web server, etc. Anybody have any ideas what might be causing this.

Oh and its Ubuntu 9.04. I think I have the 2 drives shared on all the computers, 2 running Windows 7 RC and 1 running XP. If you need more let me know.

Well, if thats true, then the system should be very noticably slow. Is it? If its not, then here's my explanation; Processors are always in 100% use, but when they are not in direct use, when the system is idling, so is the processor. Its kind of like a car, the engine is still on when its idling, its just not in direct use.

I see that in my Windows system, little hops in use even when not using the computer. But this is so much the processor fan keeps spinning up to max.

As I understand 'headless' means no monitor/display there on server.
The easiest is just to plug in monitor for a while and kick top or htop command.
This TightVNC is something that's from 'windows server' times, right?
Why not running putty? Setup ssh on the server. Then you could pop in anytime via putty. Throw top command and see what's goin on there.

PS. If you choose to plug in monitor and you have there any DE, try ksysguard. Most clean and easy to use system monitor I've seen so far.

Might be lack of graphics drivers. Sounds silly, but try it.

The fan is controlled by BIOS?

Not sure if its controlled by BIOS. Since I don't have a ton of stuff invested in this would it be better to reinstall with server because eventually I would like to try and build a web site and personal email server I can take anywhere I move to in the future.
