About a week ago, I started having a problem where after about 10-20 minutes of using a full-screen application (such as a game), my computer loses its network connection, and it is impossible to get it back unless I restart. I can no longer access the internet, and if I try disabling then re-enabling my Ethernet connection, windows says "Connection failed!". Command ping test won't run, no internet browsers can bring up any pages, and trying to repair the connection just hangs the dialogue box. Simply browsing the internet, doing email, and using word documents does not cause any problems, but if I start running a game the problem is guaranteed to happen within 10-20 minutes. Usually windows will not even let me restart (hangs on a blank desktop) and I have to do a hard reset. It happens with various games (tested on warcraft and team fortress) so I am fairly certain it is not any program in particular causing it. Playing the same games on other computers connected to the same network works perfectly fine, so I am certain it is not the network's fault either. It even happens if I play a game like warcraft 3 in single player mode (not using the internet)... and after about 20 mins I can't use the internet at all when I try again. I made sure to update all my drivers. I tried using system restore to return to a point when everything was working. I did not make any changes to the system since the problem started showing up. I did a full spyware and virus scan. Nothing is fixing this and I'm going crazy! I'm a computer engineer and am rarely stumped by problems like these...but I'm about to give up on this and format the system.

Any suggestions?

Running a game like that on a laptop could be over heating the innards. Are you running on battery or plugged in?

Hmmm, that explanation would make a lot of sense. Though...I've run the laptop in much hotter conditions for much longer plenty of times in the past without issues...so something must have recently worn out? I usually have my laptop sitting on a laptop cooling pad.

I'm running it plugged in. I discovered that going into and back out of hibernation also fixes the loss in network connectivity.
