Q shuts down my computer

[brisyd]

Whenever I connect my Q to my Windoxs XP computer, it shuts down the computer. I've tried using two different USB cables. I tried using the Motorola Phone tools first, then ActivSync 4.5.
Any ideas?

I have a PC that does that too. I even updated the USB drivers for XP that was suppose to stop the re-starts. Now I just plug in the phone when the PC is shut off and boot up.
I was going to tear apart that d*mn thing over Easter to see if I had a short, or loose connection, etc. but I didn't get a chance to.
It could be that your motherboard can't handle the "surge" that it takes to connect the phone too.
Lot's of reasons for it to happen I guess.

There can be a few reasons why plugging a USB device will cause the PC to reboot, most of them hardware related. If you can plug your Q in while the PC is off and boot the PC normally and access the Q as Geekster suggested, then its probably one of the below reasons.

Here's a few things to try:

First, if its plugged in with other USB devices, try disconnecting all the other devices and then plug in the Q. Some devices don't like to play ball when other things are connected. When I connect my Q, it disconnects my iPod Touch and vice versa, I get a "device not recognized" message on the device that was plugged in 1st. Also, having several devices plugged that require power can tax the mobo (especially older mobos) and cause a restart.

If it is plugged into the front panel USB port, try using the rear ports directly on the mobo. Sometimes the front panel connectors on the case use cheap wiring and cannot carry enough current to power a device like the Q.

If its on a hub, make sure its a powered hub. Also, try plugging it directly to the PC's rear connectors. If you have a lot of USB devices, get a powered hub, plug as many of your other devices (not the Q) into the hub and then plug the Q directly to the rear USB ports. Also, if its on any kind of USB extension cord in addition to the main cable, try just using the main cable.

A long shot might be to check to see if there is a BIOS update for your mobo and install it per manufacturers directions.

Most likely it is a driver issue and you should delete the drivers in the list of hardware devices and then unplug the phone reboot the computer and then when the computer is completely up and loaded plug the phone into the computer and let windows automatically reinstall the drivers. That should correct the problem.
