Heya everyone.

I've recently started to have problems with an otherwise good system. This issues come from no-where and I can't recall installing or changing anything that would cause this issue.

Everytime I plug my Speedtouch USB Wireless network stick into my Windows XP Computer (not laptop) windows reboots itself. Sometimes it does it immediately, other times it'll take 10 seconds or even up to 10 minutes before it reboots. After rebooting it will enter a cycle of rebooting everytime the system gets as far as the mouse cursor. Ocassionally icons will appear and then it'll reboot. As soon as I remove the USB device from the port it boots normally. I can run the computer, play games, work, do whatever and it's fine until the USB wireless stick plugs in again.

I have tried the USB Wireless stick in every USB port available (2 fore and 2 aft). My USB keyboard and wireless mouse work fine in all the available sockets. I'm currently on a wired USB mouse though after many system restores it's easier to set up.

I have run system restore to numerous points, and gone back as far as I can with that.

I have tried an indentical Speedtouch USB network stick (running fine on another PC) and it does the same. Both sticks work in a second PC.

I have removed and re-installed the Speedtouch software.

I have run a full AVG 8.0 Antivirus scan with no faults found.

I have run hijackthis and looked for anything out of place, with nothing unusual.

I have the 'automatically restart' option unticked in the system properties bar with reference to system failures.

I have run Dells System check from the Bios/Startup menu. It threw up a couple of USB connection faults that seemed hardware related. I don't have those details as didn't write them down but could get them if it'd help?

Below are system details etc:

Dell Dimension E521 (18months old)
AMD Athlon(tm) 64 X2 Dual Core Processor 5000+
1024Mhz Ram
Bios Version/Date Dell Inc. 1.1.4, 09/12/2006
Windows XP Media Centre Version 2002. Service Pack 3. Version 5.1.2600.
Internet Explorer Version 7.0.5730.11

Thomson Speedtouch 121g Wireless 802.11g Adaptor

I'm currently trying to get a Belkin Wireless USB stick to work but the software with it's not very good and it doesn't want to play ball.


Can anyone shed any light on this? I'm normally ok with computers but this has got me stumped!

Thanks

Dave
