Big update: changed thread name as it does not seem to be just lan cable, but will keep my original post, as to show how it evolved
Ok, so i am almost ready to throw in the towel.
My computer "turns off" after random amounts of time when my lan cable is plugged in, sometimes its right when the windows loading screen comes up, other times a few hours can have gone by before it happens, both my screens will just go black while the sound keeps playing, and then after a min or so the sound freezes up as well. Cant use keyboard or mouse, and the only way to reboot is manually holding down the power button.
I have reinstalled windows about 4 times now, this last time using a completely seperate windows 7 dvd and serial key (bought a new one since i first thought it might be a bad installation and i wanted win7 ultimate anyway)
If i unplug the lan cable i used it over 24 hours without a problem, about 5min after i tried plugging in the lan cable the computer crashed. I have also booted up in safe mode with the lan cable in, and there seems to be no problems when doing this.
Other things i have tried:
full virus scan on my 3 hdd's.
Full malwarebyte scan.
Using another port in my router.
Cleaned my ethernet port (integrated into motherboard) for dust.
Checked lan cable with a cable tester.
Reset my tcp/ip protocols.
Updated my ethernet driver.
I would love some help, its my christmas holiday now and not being able to use the internet would really suck ;(
(sorry for any spelling mistakes, using ipad)
update:
Just tested unplugging lan cable from router but not the computer, after about 1 hour computer crashed...
Update 2:
Ok so it is not my cable... I think, computer just crashed again, no cable plugged in... And it seems to be getting worse
