Hello OTT_Buzzard,

It would be really helpful if you or anyone else could still help me.

The laptop is:

HP PAVILION DV4 Notebook PC

Thank you for replying Mooly

The fan does not come on as soon as i hit the power button, it is after windows loads.
It begins with just a slow speed but as i am using it say over half an hour it increases speed and noise substantially

I have checked on the task manager and it reads CPU usage as 21% is this normal?

Could you explain what entering the BIOS is as unfortunately i don't know what this means?

mooly has made a good point on resources. If you processor is continuously running at 21% then there's probably something not quite right there.

That said, it may well be a different issue to your fans constantly running since your CPU isn't excessively hot.

I was looking throug the HP website looking for a copy of the user manual when i came accross this:

It's well worth having a read.

Can you have a look through the first link and see how relevant it is to you?
I can't seem to locate a copy of your user manual at the moment - this will contain the information to alter fan speeds in BIOS.

is the Basic Input Output Settings;

When your laptop is booting up it will display a message to the effect of 'Press (whatever key) to enter setup'. This is how you enter BIOS.....

I'm guessing it's Vista as it's still under warranty.
If you begin to type RELIABILITY AND PERFORMANCE into the start box you will see Reliability and Performance monitor. Click on it and look at the real time graph for CPU etc. Below the graphs are drop downs for each category and the CPU one will show what is using the highest resources at any given time. Keep the window open, just minimise it so you can keep having a look as you use the PC.
As I type this my CPU is at around 2 to 3 % with occasional kicks up to 20 or so. The fan cuts in every couple of mins for 40 seconds or so on it's slowest speed. With the PC just sat there doing nothing it should idle around 2 to 5% I reckon.
In the power options I use "Balanced" which sets the processor at 80% max speed but allows it to "dynamically" go to 100 if needed. Power plans are another topic though.
To enter the BIOS you press (usually F2) straight after hitting the power button. Keep tapping it during those first few seconds.
