I'm trying to diagnose a fault on a Pavilion dv7-4130sa running Windows 7.
The wireless connection was working fine up until yesterday afternoon when I believe there was a power surge or very brief power cut. It wasn't enough to reset any clocks or switch off the TV, cable box, etc. but I had to reset the wireless router.
The central heating also stopped working, due to a blown fuse and faulty pump - but this may just be coincidence.
Now, the wireless icon in the System Tray shows a red cross with Windows showing an error message of...
Windows cannot load the device driver for this hardware. The driver may be corrupt or missing.
I know it's not the router as my phone and netbook both work OK over wireless. I was thinking of doing a System Restore, but then wondered if the wireless and bluetooth cards are faulty, this wouldn't solve the problem.
Any help or advice would be much appreciated.

Sometimes, the simplest of solutions are the best.
After the events I had over the weekend, I put 2 and 2 together and got 5.
I simply uninstalled the wireless adapter driver and let Windows detect and reinstall it upon a restart - which it did just fine.
The 3 Bluetooth drivers, however, are another story. Seeing as this feature is rarely used, I shall take a look at a later date.
Incidentally, the central heating pump failure was not caused by a power surge - it was just coincidence that my router needed rebooting and some Windows drivers decided to go AWOL.
