When you press the power button and expect it to hear the fans whirl up, but nothing happens.

Sometimes somebody (obviously not you) bumps the computer and knocks a cable out just enough for it to look like it's plugged in, but in reality is not. Take some time and gently push the power cord into the power supply and check to see if the power switch was flipped off.

You may have a faulty memory module, try removing one module at a time, booting with one in at a time. If the computer boots with one module you have to replace the other module.

Sometimes power supplies go bad. You may have too little voltage running to your computer and you must replace it. Luckily for you we have a guide on how to replace it.

Please do not try to disassemble the power supply unit in an attempt to fix it, doing so may seriously harm or even kill you.

Some things to check before throwing out your speakers

Check to see if your volume is muted through the task bar.

  • Are you speakers plugged in and turned on?
  • Is the audio jack plugged into the back of the computer?
  • Remember to make sure all connections are secure.

Head to the Dell website and locate the "refine your results" group, click the categories dropdown box and select audio. Scroll down until you find your results and download the installer.

My keys sometimes stick, or my keyboard isn't recognized.

More often than not, you have something sticky under the keys. The best thing you should do is pull the key off and clean underneath the key. Don't worry, they snap back into place when you're done.

  • If you are using a wireless keyboard check to see if the batteries are dead.
  • If you are using a wired keyboard check to see if the connection is secure.

I can't get my computer to recognize my optical drive or floppy drive.

You may need to go into your bios (by holding F2 at system boot) and enable your onboard SATA devices.

You may have a faulty optical or floppy drive and you might need to replace it.
