BSOD occurs randomly


I keep getting random BSODs while playing, surfing pretty much doing anything.
The thing is that it can occur anytime but mostly happens like once every 3 days or something like that. Since i don't know why i keep getting them and it's really starting to bug me I followed the:
[1 - Novice] How to ask for help with a BSOD problem

And here I am

I appreciate any help I can get

It looks like your Atheros Ethernet Controller driver L1E62x64.sys is causing the problem.

I recommend updating your network card drivers, or uninstalling them and see what happens.

Good luck!

An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arg1: fffffa811e617da8, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, bitfield :
    bit 0 : value 0 = read operation, 1 = write operation
    bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: fffff80002f507a8, address which referenced memory
