Suggestions

May be normal Windows behavior (background processing can affect response time).

Certain background operations (such as VirusScan) can affect performance.

Press CTRL+ALT+DEL to see if an application is not responding.

Restart the computer.

If the hard disk has spun down to conserve power, it can take several seconds to spin up (you can hear this). You can use the BIOS Setup utility to change the hard disk time-out to match the Standby time-out.

Some file browsers respond slowly while processing graphics or waiting for broken network connections to time out.

Check for overheating—see the previous symptom.

If the computer’s hard disk drive frequently runs (as indicated by the hard drive light on the front of the computer) while the computer appears to be paused or running slowly, consider installing additional

SDRAM.

Check the amount of available free disk space. Delete temporary and unneeded files.

Run the BIOS Setup utility and set the Power Management Mode to Max. Performance.

Run the BIOS Setup utility and turn off Intel SpeedStep Mode.
