Query: locked up my pc

I bought a new Canon REBEL EOS, and a few accessories, one being a Transcend 8gb card. It works in both my cameras, and the other cards work in both. The Transcend 8gb freezes the screen every time it is inserted in to the reader slot on my pc. I tried it in my wife's pc and same thing happened. I cannot download any photos from it. There are photos to view on the card, and I can stick it in my A-560 and view it, but that's it.No stars untill I can get another and see if that does what it should.
