Windows 7 x64 suddenly wont pickup bluetooth devices

[thingemajib]

Bit of a strange one that I can't quite pinpoint - booted my desktop up this afternoon and the (Bluetooth) mouse wouldn't respond. To cut to the chase it appears that the windows bluetooth software/service/whatever is broken. After removing the mouse from the devices and printers panel, I tried to readd the mouse and it would just get stuck on the 'searching for devices' box. It simply fails to pickup any bluetooth devices at all (tried with my phone as well), yet it claims bluetooth is enabled. My desktop has a gigabyte wifi/bluetooth combi pcie card (GC-WB300D) and I have also tried a little 6ish year old generic usb bluetooth adaptor. Here's a brief run down of what I have tried:

swapping mouse batteries out - fail
disabling/re-enabling bluetooth - fail
rebooting - fail
uninstalling/deleting/reinstalling drivers (with appropriate reboots) - fail
physically unplugging card, inspecting and refitting using different internal usb header - fail
disabling gigabyte card and using generic adaptor - fail
system restore to 28th jan - fail
pairing mouse to laptop with built in bluetooth - success
disabling laptop bluetooth and using same generic adaptor on laptop - success
fresh install of windows on spare drive in desktop - pending

Now bluetooth isn't my forte so chances are its just a setting or something but it beats me as to why it would do this by itself if this were the cause. It was working fine last night, and has done so perfectly without intervention for the last few months. One thing that might be worth a mention is that we had a power cut this morning and the desktop was on at the time, although the rest of the desktop is working just fine...

thoughts?

Got the disc for the drivers and or a download from the manufacturers website? Might need some drivers to be installed from there?

I've just had similar. Went into devices and printers and it stated my laptop had a problem, troubleshooted it and it came back with Bluetooth not work, ran the fix and it's ok but now I have USB-IF xHCI USB Host Controller has a driver problem and it can't fix it. All my USB devices work but as I don't use Bluetooth devices I'm unable to test bluetooth...starting to think that a Windows Update has done some evil work. Like to hear if there are some solutions.

drivers are off the disc and there arent any newer ones online

forgot to mention ive also tried a system restore to 28th of jan which was when windows last ran an update. ill let this new instll finish and see if that solves anything, if it does ill try an earlier restore to before to see if it is windows update upto no good

OK, it seems my initial testing wasn't that thorough, the fresh install still shows the same symptoms on the gigabyte card, however the generic adaptor worked. Reverting to my current install and tried again - card still doesn't work, but adaptor now does work! Reverting to earliest system restore (25th Jan) makes no difference

Starting to look like its a problem with the gigabyte card and not windows. Again, can't help but wonder if this mornings power cut had something to do with it. The pc was running constantly for the previous 4-5 days beforehand
