I'm running off of two different video cards, both of them are nvidia, one is a 430 gt and the other is a 520 gt. I am having a strange problem, when my second monitor which is connected to the 520 is on my internet slows to a stop but comes right back if I turn the monitor off. Any ideas on how to fix this would be greatly appreciated.

Processor: AMD Phenom II x6 1055t
RAM: 6 GB
Motherboard: MSI 890FXA-GD70

I switched out monitors but nothing changed as long as both are on the internet is not I did find that it does not matter which is off just so long an nether is on at the same time.
