For a week now, my laptop's fans have been running full speed as if a process is running in the background. I've tried everything I know of to resolve it. Rebooted numerous times, cleaned registry, virus scan, full system scan, terminated processes using too much CPU memory, yet the problem persists. Its affecting page loading and searches when I'm on the internet, file retrievel, and gaming is jumpy.

Any suggestions?

Thanks...

The PC's fan speed should not affect the PC's performance. I suspect you have something keep the PC very busy causing the problem. The first thing to try is a System Restore and select a date before the problem started. Windows Help has more details on System Restore if you need it.

It may be simple dust buildup, get a can of compressed air and blow it out. If confident, you may disassemble the laptop and simply blow the dust out with your mouth or use an anti-static brush. The fans are going on because of heat buildup, either cause of blockage or high CPU consumption. Some viruses may cause your symptoms as well.

As long as you don't go inside it is just as easy to vacuum the vents from the outside with one that has good suction.
