What are the specs for your system?
I have the same problem (only it's very rare) with my external HDD not starting, but I know it's a "lack of memory" issue. In your case, it may not be the bluetooth at all. Try running ccleaner and/or Advanced System Care to clean up your system and see if conditions improve.

 

I have an AMD Phenom X4 940 (3.0 ghz), 4GB RAM (I don't remember the exact specs of the RAM, but I know it's DDR2), Windows Vista 64-bit.

I'll run CCleaner and see what happens.

 

I ran CCleaner and it made no difference.

 

In general, there have been lots of problems with Power Management/Vista on 32 bit systems (let alone you have 64bit!)

Are you running SP2? Do you have all the critical and hardware optional Windows updates installed?

 

Yes, I am running SP2 and do have all updates installed. Anything I can do to try to resolve the issue?

Also, not sure if this matters or not, but I forgot to mention that this problem just recently started. For the first month or so of having my bluetooth card I had no issues like this at all.

 

Well, there's one thing that was true for most ethernet drivers (let's see if applies to your BT)

Open Device Manager and find the BT driver under network adapters. If you rt click Properties, do you see a Power Management tab? if yes, uncheck the box for Allowing the computer to turn off the device to save power

 

Nope, no power management tab. I did find something interesting tho, not sure what it means. But, in the General tab it says "This device is working properly" but in the Resources tab I get the message "This device isn't using any resources because it has a problem."

Know any way I can try to find this problem?

 

Go back to the General Tab. Look for the Device Status. Does it say working properly? Or does it have an error code?

 

Just says it is working properly.

I'm also having problems with my wifi not working after waking from sleep now, and when I try to go into the network and sharing center it just locks up.

 

So, I tried reinstalling the drivers, but things just got worse.

I now get a 1000007e BSOD when I try to shut down the computer and it has something to do with wltbus64.sys. I had this problem when I first installed my bluetooth/wifi card, but I reinstalled everything (including reseating the card) and the problem disappeared. But, since it came back, should I take this as a sign that this thing is not 100% compatible with my system?

Anyone know of possible fixes for this?

 

Try this to cleanup device manager entries... (not these instructions apply to Vista as well)

Unplug your BT device

See here to display all non-present device

Then open Device Manager, click View->Show Hidden Devices

Then look for all the Bluetooth entries, rt click uninstall and reboot
