CPU running at 100% on LG F1

Hi,
I have installed Windows 7 on an old LG F1 Express Dual. Now the CPU runs at 100% all the time, which causes the fan to do the same.
I've tried disabling SpeedStep in the BIOS, but then processor get stuck at 800MHz.
According to Windows Task Manager CPU usage is around 5% when running only the browser. Process Explorer shows the same info.
Cant see other processes steal anything either, but processor runs at 1.73 Ghz all the time.

Found a forum with updates for LG BIOS, thought maybe this could help since it looks like it's SpeedStep making the trouble, but have never tried to update the BIOS before, so it would be nice if anyone had tips for other solution.

I mean if i sort the processes in Task Manager with the heaviest process at top, i got the Chrome browser on top - but this is only using 5% of the CPU.
CPU-Z is telling me that my core speed is 1733,3 MHz, which is 100% for my processor.

You are right.
In BIOS i have set SpeedStep to default, wich is called auto - this is when it locks on 1.73 Ghz. When i had XP installed, SpeedStep adjusted the CPU after system need, but now its just stuck.
If i dissable it it will lock on 800Mhz

Thanks! Just tried loading optimized default, but no difference.

Do you have show all processes from all users selected in task manager when you do this?

Yes, there is only one user on the computer, wich is the admin-user as well.
