Blue Screen of Death, athrx.sys

Recently, I've started getting blue screens of death far too regularly. The error is 'Driver_IRQL_Not_Less_Or_Equal' and the file implicated is 'athrx.sys'. This has been happening for a while, but as time passes, the computer has started crashing more and more regularly. Any ideas?

Additional info: this has happened quite a few times (not sure how many; Blue ScreenView doesn't list more than five identical bluescreens) but it's gone under three times this evening alone. This is getting way out of control; could use help as soon as possible.
This is what it looks like:

  1. start with the easy stuff open the case..see if the fans are dust bound.also check that the fans are moving. run memtest to see if one of your stick of ram is bad..also run ccleaner and malware bytes and a good anti virus software.

    Sorry if this is old, but came across this via a Google, and others probably will too. The problem here is not RAM faults, dusted fans or malware. It's the Atheros wireless driver that Windows 7 installs automatically. You need to remove this driver and install an updated driver. You can find updated drivers from the manufacturer's website (i.e. TP-Link) or from Qualcomm/Atheros.
