Lately I've been experiencing fan problems and how its really really noisy. I started to notice that the CPU Usage levels were fluctuating high and low. It would start out as 3% go to 9% then 30%, 40%, 70% and eventually 90% and the highest was 99% and then it would go back to 3% and start this process over again. When the CPU Usage goes higher the fans start to become louder. I had just booted my computer and opened firefox and had ONE window opened and the CPU Usage went up to 99% and the fans were INSANELY LOUD. I thought my laptop was going to blackout.
Is this happening to anyone else? Is there a solution to this? I don't do anything with my laptop like intense gaming or anything. I'm just a student that uses this laptop for word processing, internet browsing, music, instant messaging and a little photo editing. I don't see why my laptop would just suddenly go crazy like that. I just bought this like 2 months ago back in July..
Help is much appreciated!!

Run a scan on the PC to check for viruses if no virus, Close all the windows, press cntrl+alt+del brings the task manager, click on the processes tab and let us know which of the process are occupying more memory.
Work around : Type 'msconfig' in start search and click the services tab uncheck the programs you don't use click 'Apply' and 'Ok', Restart the PC and check.

For my Pavillion dm4 laptop, I installed the BIOS update that was listed as a recommendation by HP Advisor/PC Alert. After doing that update and rebooting, I also then went to Start, Control Panel, Programs, Uninstall a Program and installed all of the Norton Internet programs and rebooted again. CPU usage is now showing consistent 0% with NO SPIKES and my fan has stopped cycling between rev up and slow down!!! Good luck!

I also had the 100% CPU usage error on my Pavillion dm4. I verified that no applications were causing the excessive usage and performed a virus scan on my computer while it was running in this state. The BIOS update obtained through HP Support Assistant seems to have fixed the problem. The CPU usage went down when the update was downloaded and installed (before the required system restart).
I just recently performed this BIOS update, so I will post again if I find that the problem resurfaces.
