Flashing bios in dos

Hello,
i have a hp pavillion m7630.uk media center that needs the bios flashing, it won't boot into windows because it keeps blue screening, the update says it cures various blue screen issues but the only bios available is a windows version, iv'e extracted the bios files from the exe but not sure how to mount them or put the computor into a flash mode! any help would really be appreciated.. thanks paul...
