Uploading photos onto the computer

I used to be able to do this before my computer went kaput recently. Thanks to my Uncle who did all the dirty work and got it up and running again; but now I can't do it. I used to upload them to Picasa, but it won't recognise the USB drive like it used to.
I noticed in the camera manual it says:
-Operation is not guaranteed on models with an additional USB interface board
-Operation is not guaranteed on home-built PCs or on PCs running updated operating system software.
So, if it would upload using the USB port at the front of the computer, how else can I do it? Or is there no way at all around it because of what the manual says?
