Asus P8 z68-v pro motherboard
Samsung 840 Evo hdd
16 GB Ram

My computer becomes extremely laggy anytime there is something downloading. Large email, movie loading, file transfer, ect. The mouse becomes jumpy and sometimes almost non responsive. As soon as downloading is complete the computer goes back to working properly. At first I thought it was my hard drive so I bought the Samsung 840 with fresh install of windows last week. I get the same results.

I also ran memory and CPU stress tests and everything came back perfect.

In device manager everything is working properly.
Intel (R) 82579V Gigabit Network Connection (Driver Date 8/21/2013 - Driver version 12.10.28.0)

Netgear WNA3100 N300 Wireless USB Adapter (Driver Date 4/19/2011 - Driver version 5.100.68.48)

Anyone have any ideas of what could be causing the issue.

How are you connected to your network? Ethernet or Wireless?

If you are on wireless, see if you have the same issue when connected via ethernet (if possible).

If perhaps you have connections on BOTH wireless and ethernet, disable one or the other.
