Win7 ethernet problem

I've just bought a new computer with Win7 Ultimate 64b but the ethernet is going down alot. Sometimes it can work for a day and then my sound is not "rushing?". But when it's not working it goes down every 1-40 min depending on what im doing. So if im Downloading it will go down more quickly then if i am gaming.

My other computer with VISTA did have alot of problems but not this one and the ethernet is still good on it.

h/e this seems to be a software problem cause yesterday when i uninstalled my motherboards sounddrivers it went good until the next day when i started my computer again.

And sometimes it's good when i change some advanced properties in 'local area net work' BUT, just untill i turn off the computer.

If you buy a new computer you should not be having a problem like this.

If you know the computer manufacturer or the motherboard manufacturer you should check their website for drivers for Windows 7 64bit*

Otherwise, if you are not having a driver problem, you should consider checking your wires and connection.
