My router is a Linksys

In my case is not an issue of temperatures, I have all my equipment under liquid cooling, and I use games with higher requirements.

I can play some. Within 1-5 minutes. The process steam, chrome and dayz crashed. I've tried beta and olds nvidia graphics drivers but still the same. I have also tried to disable SLI, even put the graphics settings to the minimum.

2xEVGA 580SLI
Windows7 64

(When I play DayZ sometimes it decides to crash my chrome, ts and steam for no apparent reason and after that proceeds to freeze/crash itself and often loops a sound.

After this have happened I need to restart my computer in order to get any of these programs running again or else they just refuse to launch.)

Same here, i have win7 64 bit, 580SLI
