OK, this has a bit of a plot...

I bought a 6-in-1 USB2 card reader for my WinXP machine. After about 2
minutes plugged into the USB2 port, the machine resets, as if someone has
pressed the reset button on the case. If plugged into a USB1 port, no
problem (both USB1 and USB2 ports are on the motherboard)

Since then I have:-

Bought a new PSU, now running at 400W.

Bought a seperate USB2 PCI card, and turned the onboard USB2 ports off.

Bought a different USB2 card reader.

Still getting exactly the same problem. Out of interest, a USB2 printer
works fine.

Any insightful comments would be much appreciated.

Right click on "My Computer"
Select "Properties"
Select the "Advanced" tab.
Click on "Startup and Shutdown/Settings"
Un-check the "Automatically restart" box under "System Failure"

Something is probably causing a BSOD. Your system is probably set up to
reboot on a BSOD instead of showing you the message.

Right click on "My Computer"
Select "Properties"
Select the "Advanced" tab.
Click on "Startup and Shutdown/Settings"
Un-check the "Automatically restart" box under "System Failure"

Now you should get a message for the BSOD. Copy all the parameters.
Hopefully it will tell you what is failing. You undobtedly have a bad
driver or a bad USB device.

Click to expand...

Are the USB ports (to which you are connecting the peripherals) HIGH
output ports? Or are they just the standard USB ports? You might have
to use a powered USB hub (which provides its own power via AC adapter
rather than suck it from the PC's power) between your mobo's USB ports
and the high-power USB device. A USB printer is a low-power device
because it has its own internal power supply. You didn't mention
anything about what motherboard and model you have or which USB port
card you bought so no one can check them out to see if they provide
high-power USB ports, but at this point you could check that yourself.
