High background noise when trying to talk computer to computer

I have a Dell "Smart" computer using Windows Vista. Recently I've started getting so much background noise I cannot hear or people cannot hear me. Skype tells me to move away but there is no where to move to.

There is a possibility of any number of issues. Radio, emf, radar, cell phone....so on... all can react with pn junctions and produce a whole range of noise.
Does it do it with only the battery installed and no external power source? Does it do it exactly the same when the laptop is moved to a different location?

    If the loudspeakers volume is on to the full extent, you may hear some static noise. So just try to lower the volume to the middle and then listen for background noise.

Do you still have a warranty with Dell? I am going to refer you to your manufacturer's website: http://en.community.dell.com/Search/SearchResults.aspx?q=high%20background%20noise
Basically, you will need to isolate the problem one by one, taking turns with the internals of the computer to find out which is making the high background noise. The fan is the easiest to check so do that one first. Then one by one, turn on the pc after taking another pc component out and check for noise. Do this until you have found the hardware causing the problem.

These features are normally turned on in the Bios. The bios is normally accessed by clicking the del key on the laptop at boot up. Once in the bios you should get a different screen normally black background with blue writing. Please read the options carefully on the screen as it clearly explains how to turn on and off different options.
you should have an option to turn off key click noises and also to turn the fan from high performance to compatibility mode to reduce noise,

Vista Blue Screen (Not BSOD)


When you try to use Windows Vista, Windows Vista may not behave as expected. For example, some Windows Vista functions may not work, or Windows Vista may stop responding. This issue may occur if a Windows Resource Protection (WRP) file is missing or is corrupted. To resolve this issue, use the System File Checker tool (SFC.exe) to determine which file is causing the issue, and then replace the file. To do this, follow these steps: 1 Open an elevated command prompt. To do this, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow. 2 Type the following command, and then press ENTER: sfc /scannow The sfc /scannow command scans all protected system files and replaces incorrect or corrupt versions with correct Microsoft versions.

Hi,
your conflict or problem is with vista drivers.
get the latest updates from M$ for your machine.
Why do people always assume, that the latest is the greatest.
Vista is a pile of unfinished junk.
windows 2000-XP are far superior operating systems.
Vista is unfinished, like most microsoft products.
never get fully tested and debugged, they let the consumer find the floors.

Windows Vista can't find networkd Dell 1600n


Make sure you're using the drivers for Vista, which can be found on support.dell.com. You'll want to use the choice for Vista 32-bit.

Also, try turning off your firewall, as it may be blocking the network data.
