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.
