Random BSODs

[sezercik]

Hi;

Random BSODs with Windows 7 Ultimate x86 installed computer. Sometimes it goes for hours with no problem, sometimes it just crashes after 5 minutes. No pattern that i'm aware of. OS was installed after a clean format last week.
Also there's a problem with Atheros L1 Gigabit Ethernet 10/100/Base-T Controller. Computer seems to have internet connection but it doesn't work. This also happens randomly. I have to roll back driver or uninstall/reinstall. I thought that the cause of BSODs was this device's faulty driver and uninstalled it but computer crashed anyway. Driver seems to be valid according to manufacturer.

I appreciate any help. Thanks in advance. Sorry for my lousy English.
Good day.

Sounds like a hardware issue with your network device. I see that you do not have your system specs filled in totally. It would help us for any future problems you may have to know what hardware you have in your system.

Have you tried disabling the device hardware manager just to see if it stops the BSoD? If it does, you may want to install a third party network card to use.
