Randomly Occurring BSOD's Driver Irql not less or equal

Recently my PC has begun to BSOD during use. I've read through quite a few other threads on the same problem and i have general understanding of the cause of this problem.Could anyone offer any assistance on how to prevent future BSODs? I have attached dump files i attained from SF Diagnostic Tool.
Thanks in advance

More information is required.

You are getting errors from your Atheros NIC driver, I need to know what exact version you have so I can point you to the correct driver.

This indicates your Atherso NIC driver has caused a page fault.

Thanks for the reply,

Device Manager shows that the version of my driver is version 2.1.0.7

Sorry I mistyped what I meant.
I need to know your exact network card type from Atheros.

No worries,
I have a Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.20)

Hmm, the latest version was released in 2010, we can try it anyway.

Drivers for Atheros AR8151 and Windows 7

Make sure you create a restore point before altering drivers, create one by following these instructions

System Restore Point - Create

Sorry for the late reply,

After downloading the driver i selected "Browse my computer for driver software" and directed it the folder with the .inf files. It then displayed that Windows determined the driver software was up to date. I should also note that no further BSOD's have occurred since i posted this thread. Could the recent BSOD's just be some kind of intermittent hardware issue?

Thanks for the help so far.

No, I very much doubt it's hardware related. Post back if you get any more BSODs.

Alright thanks. I will go ahead and mark this as solved since i have not had a BSOD for quite a while now. Thank you very much for your help.

That's good news :)
Any more issues keep us posted.
