Blue Screen Error but no actual blue screen pops up

Take your time.

OK so it looks like your Dell wireless card is the one that is using an Atheros driver, so go here: Drivers & Downloads | Dell US and expand the network section of the page and download the driver I have circled in the attached:

Have you tried downloading the installer ot another computer saving it to a flash drive, external hard drive, or cd and then transferring the removable media to your laptop and installing it from the removable media?

Best of luck.

Please run the SF tool again click grab all and let us have the new dump files so we can check if the driver has updated and see if theres any more info on your recent crashes :)
