For the last few days, I have been unable to boot into Vista because my computer freezes when any of my USB devices are plugged in during the bootup. I will get to the BIOS/Dell screen when the computer freezes although the lights and fans on my XPS 720 continue to run. When I try booting without any USB devices plugged in I get a keyboard failure and then boot into Vista where I can reconnect the USB devices and then use them normally. If I try to reconnect any USB device during bootup, the computer immediately freezes and does not continue booting upon disconnecting the USB device.

This is beginning to get really frustrating and I am wondering what may be causing this problem.

I have tried a system restore to no avail. I've tried reinstalling the drivers for my USB devices without success.

 

If anyone else knows of or has this problem, please post suggestions/solutions because this is really getting on my nerves.

 

Thanks for any help.
