Question about Compaq Presario 700 470024-192 Notebook

I have a Compaq F700. It just (within the last 20 minutes) started making a really scratchy sound, NOT from the speakers. It sounds like something came loose but I'm not sure.

My compaq presario f700 producing a strange noise from the speakers,and the sound quality is compromised.What could be the problem?


You could be having issue with the speakers the connection or the sound card. I would try another set of external speakers and go from there if this does not work replace the driver if this does not happen you may have a board issue. John

The speakers are making a very scratchy noise. They are hooked up to my desktop computer. When first purchased last year, they sounded quite good. Now, they are very scratchy and not on high volume.


Do you by any chance have any other wireless device like a cell phone near the speakers when you hear this?

Any kind of device that has a magnet field will cause scratching sounds on the speakers. I discovered this quite by accident with my old Boost mobile phone.

Have in built sound card in D845HV mother board. Experiencing heavy distortion as soon as the mic is connected. It was working well till last month.



Distorted or scratchy sound can be caused by several problems. Improving the sound can be as simple as rearranging your hardware components. The following suggestions may resolve the problem of scratchy sound:
  • Are there any other devices around the speakers or wires for the speakers? Electro-magnetic interference can cause poor audio. Try moving your speakers and wires around and away from other devices.
  • Have you recently added any new cards to your computer? Cards within the computer can also cause electro-magnetic interference. Try moving the card to another location within the computer, if possible.
  • Verify that you are not encountering a hardware issue with the speakers you have by trying another pair of computer speakers.
  • Poor audio quality or low volumes may occur if you are using passive (non-amplified) speakers.
  • Are your speakers too close to your monitor? The speakers can pick up electrical noise from your monitor so move them farther away. Subwoofers should never be placed near the monitor because their powerful magnets can interfere with the picture. They should be on the floor to maximize low-frequency transmission.
  • Are you experiencing sound problems only with particular games or programs? If you notice sound problems such as stuttering voices and static on some games or programs but not others, check with the software vendor for a software patch.

Also make sure to inspect your microphone, and the cord that connects it to your PC, for physical damage.

If you're still experiencing issues, you may need to replace the your microphone.

I hope this helps.

Re: scratchy speaker sound quality


Have you tried with headphones?  Scratchy WITH heaphones. Reinstall driver. If it's NOT scratchy with headphones.  Either your speakers are blown, (which usually doesn't happen), you need to reinstall your sound card drivers, or bad settings.  Double click sound horn. Turn some volumes haflway, or mute sound channels you aren't using. Options Properties will let you show ALL sound properties. Ctrl+S makes the sound properties half size.
ReInstall Drivers: Start - Settings - Control Panel - System - Device Manager, Expand Sound Controllers, Right Click on your sound card, Click Uninstall.  Reboot and reintall.  
Might ask to reinstall automatically.  Thats fine.  Install then reboot.  I prefer to cancel the install until I have rebooted.  But both ways tend to work.  
Hope you don't have to change your speakers.  Need to pull your mobo to get to em. Instructions here pg. 5-55

Scratchy Sound, Major Problem


Try the speakers on another PC with good working sound. This will indicate either a speaker problem or a sound card issue.

If speakers work ok on 2nd pc, then you have a sound card issue on your pc. If speakers are still scratchy on 2nd pc.. check the metal connector end, make sure it is clean and shiny. If there is any rust or other oxidation, clean it off with a very fine grade of sand paper

Starting system cold, no sound for 2-3 minutes


Its not worth having it looked at. $100.00 for a new 400.00 unit? My unit is doing the same thing. Turn it on and 2 to 5 minutes later it may come on. Change to video 3 4 5 etc it stop again. Only works with a cold start. Something in the unit has failed and is heat related. My original Kenwood 20/20 recevier still works. Must be 40 years old. New products just last 5 to ten years max if your lucky.
