Windows encountered problem

[Finlay]

I all,
I have a problem on my Windows Vista that began afetr the purchase of an external Hard Disk Freecom.
A few days afetr the purchase I disconnected it while it was writing and, since that moment, every time I connect and disconnect it, the PC go to freeze mode for 5 minutes.
The same thing happen even if the hard disk is disconnected: every time I start windows it go to freeze a little after the password, and every time I connect and disconnect a usb device.
I have looked for the solution everywhere, updated windows, unistalled and installed the hard disk from the device manager but I solved the problem only when I restored a recent backup.
Yesterday the Hard disk was writing a backup while Vista was installing the updates; at the end of the proceure windows restarted automatically and the problem began again!!!
The Pc go to freeze when it starts, every time I connect or disconnect the hard disk, an usb earphone that has always worked switch on but there is no audio and I don't know how many others usb devices will have problems.
Has anyone an idea to solve this problem before I throw out of the window Vista or the the hard disk?
Thank you

How much was the hard disk ? If there is no solution I recommend just using your hard disk on a diff PC not that one anymore. Have you tried taking a backup and re-installing vista from the CD ?

I can only recommend you to safely remove the hard disk (right-click >> Eject) and see if other Vista's have the same problem. Of course, the HDD could be virused so check it out.

I've tried the disc on other PCs and is ok.
meanwhile thanks the same to all.
