Not sure if this applies to you, however it worked perfect for my buddy. He was so warpy even his own team complained about it. He had a great computer, good connection, but his variance on his network status was horrible. Tried graphics, cutting processes, nothing worked. I remembered reading about Power settings in here and this did the trick.
Go to:
Control Panel
-Power Settings
If its on "Energy Star" change it to "Home/Office Desktop"
Cured it right there.
Good luck and I hope this is what plagues you.
