This is beginning to piss me off now

This eve the PC has been nothing but trouble! It's frozen 3 times (for no alleged reason - one time it hung while trying to send a file to my phone, 1 time it hung while I was trying to open a picture from my documents, and the third time it hung while I was was checking the net connection properties ) and crashed twice - with that no warning crash where suddenly the screen goes blank and it goes to the blue DOS screen with white words that say Windows has encountered a problem and has shut down to avoid damage etc.... where you can't do anything except turn it off at the power button

Thing is, it HAS to be a problem with the bluetooth device as I had this same prob before when I installed the bt dongle and the BLuesoleil software originally, and had to System Restore back to before I installed it to cure the problem. And it wasn't doing this a couple of days ago - has only done it today which is the day after I installed the Widcomm software and bt dongle....

I don't really want to have to reformat the entire drive
