HELP! USB card shuts down laptop???

I just bought a usb 2.0 2 port USB PCMCIA card. When I try to install it into the slot, my laptop automatically shut off. I think it has something to do with the driver, but I'm not sure what. It came with a cd with the driver on it, which I believe I've loaded correctly (pretty simple), but after I shut down, put in the card, then start up, just as windows is starting everything will shut off. I can go into safe mode and it will go in fine, but as I mess around with enable and disabling drivers, it will again shut off. Please help!

 

What version of Windows?

 

Windows 2000
- the more I think about it, it seems like the usb card either must be bad or has a conflict with my system; rather than a driver problem. I can swap out a modem card into the same PCMCIA slot without a problem. But when I try it with the usb card, during windows boot up, the laptop will buzz and completely power off - I then have to remove the laptop battery just to get it to turn on again.

 

Some PCMCIA cards you cannot hot plug and I am sure USB might be one of them. Do you have any USB ports on the laptop that are built in? Is the card the correct type for your PCMCIA slots?

 

The laptop is a Compaq, about 4 years old - there are no built in USB ports. Initially I did not try to add the card hot, I loaded the driver from the cd provided, then shut down, added the card into the PCMCIA slot (that I know is good), then powered back up - as soon as Windows started booting up, the laptop shut down.
When you ask if the card is the correct type, I think it is. It's plug in side looks just like the modem card I have which works in this slot, and it fits into the slot just like the modem card does. For some reason though, as soon as Windows starts to recognize it, it freaks out with a buzz, and shuts everything down. I even have to remove the batteries and power cord to be able to power up the laptop again.
