Windows 7: Bluetooth stopped working after anytime upgrade

hii friends
i have upgraded my windows 7 basice into ultimate,and ever since the day i hav doen it, i am unable
to pair any bluetooh device with imy laptop.eventhogh the bluetooth deivce is powerd on and working perfectly ,it says "please turn on your device and search agin"..i tried every thing like uninstalling and reinstalling,but still problem exists.
i am tired of doing every possible trick with it but still the problem is same. could somebody help??

Did you go to services (from search) and make sure bluetooth is set to automatic?

I think this has to do with Windows 7 not having the service running, so you need to enable it. Click on Start, right click Computer, click on Manage, browse to Services, and check that the service is started.

hay richard i appriciate ur reply''
ya i checked with services. it was already in automatic status.even i installed updates after upgrading but still problem exists..could you suggest smthing??

no friend the status is automatic over there.

Go to device manger, look for any yellow warnings stickers showing problems with bluetooth drivers. Make sure drivers are up to date.

ya i tried..as i mentioned..i reinstalled drivers for bluetooth

Uninstall them again, and try this - Drivers and Downloads
