So now you've narrowed it down to your machine. And maybe the sound card, since this is where the game port is located.

Are your running a Sound Blaster? Great cards but should be sound *******s. There are a lot of issues with SB cards and everything from mother boards to video cards.

If its an SB go to their site and do the look for updates. There is an automatic process where they examine your card before and then tell you what updates you need. You can also perform it manually.

Be warned I have experienced total screw ups when updating Sound-blaster Drivers. Sometimes your better off uninstalling the old ones first.

If you have a backup program you might consider backing up C:\ or wherever your OS is. Take a checkpoint with windows before your start so you can back out if you need to.

The last suggestion I have is to try to locate a standalone Game port and install that.

Over here the chain computer stores allow you a 30 day return so if its the same down there go buy the card and try it.

As I write this I keep thinking of more things. Could you swap sound cards with your brother. It won't cause him any problem so long as he leaves the machine off until you run the test.

Uninstall yours, install his and try the card. If his works then you know it is most likely the sound card.

Last but always a winner, check the forum again you have more info now. Also search the sound card vendors site for issues.

Good Luck, let me know how your making out. BTW, I bought G2 with the USB connection. It runs ok in XP but it crashes XP too. Very intensive processing and I have a high end machine with 1/2 gig of memory.
