multiplayer lag problems on starcraft 2

[kungfueeyore]

I just bought a new computer and I've found that when I run SC2 I lag terribly after 1-2 games and eventually dropped. This only happens when the graphics are set above low. I should be able to handle the game on ultra settings. I sometimes lag even on the lowest settings while my 5 year old laptop doesnt have that problem. Sometimes the system will reboot when its overwhelmed. Here are my specs:
Intel i7 3.07 ghz
Nvidia Geforce x465
windows 7 64 bit
6 gigs of ram

I updated my video card driver and my fps is about 60. Also, while watching one of the movies on high in sc2 my computer rebooted. Before, I wouldn't be able to log in to bnet because it said I had a connection problem but once I opened firefox, I would log in. When any new information was needed, I would have to refresh a webpage and suddenly bnet would work for that small window as well. Don't know if the two are related or are separate issues. Help is much appreciated.

Download and install hwmonitor
and see what the temps etc are. Download the 1.17 setup, english on the righthand side.
....take a reading when not running the game CPU(core) and GPU Video card and post them. (Just a screenshot of results is fine)

Then run the game for 10min or so and take another reading post the results

Temps seem OK.

maybe a hint that if you run the games on low it is OK.....I would think your video card maybe having problems

Try lowering the screen resolution and see
