Windows Crashes randomly

[Nasse]

Hi.

My computer had now about five crashes. Im running on Windows 7 64bit. Computer crashes random times. Sometimes in desktop or browsing internet. Sometimes playing games. I only have
one minidump cause CCleaner wiped my minidumps. Can someone help to detect what is the problem?

BSOD have some text like this:
IRQL_DRIVER_NOT_LESS_EQUAL 0x00000D1

And sorry my bad english..

These errors are both related to your network/LAN driver
