The most common cause for noise like this is the laptop PSU. They're often badly designed.

When you encounter this noise, try taking out the PSU plug from the laptop so it's running on battery power.

If the noise goes away, there's your cause.

The easiest/safest/cheapest way to solve it is to use GLI's (ground loop isolators) between the laptop audio output and whatever it feeds.

 
thanks groovindj i'll look into that and keep you posted....
 
Another suggestion (quick, easy, and cheap - less than $1) is try plugging you laptop power cord into one of those ground eliminator adapters (usually orange or gray) that disconnect the ground from your power connection. I have been using one of these since I started using my laptop 3 years ago and it has helped tremendously.
 
ok guys guess what? No problem anymore!!! Because... I got a new laptop for cheap! It has an i3 processor with 4 gigs ram!
i think it was the computers ports. But now im having other issuses...
