😡 my mmc card used to work on my pc. but recently i bought a new hard drive, when i connect my n-gage to my pc it shuts my pc down. i tried connecting to a friends computer and it worked fine. ive tried formatting the card on my n-gage that didnt work. so i think its a problem with my pc not my mmc card, ive got a pny 64mb card, and im running windows xp pro. Can someone please help?
