hi, ive just recently got a MSI gx600 laptop, when i turn it on the msi logo appears for a second then the screen goes to blank with a small blue box saying enter password, i believe this is the bios password, i cant get passed it, ive looked up numerous sites but to no help, ive taken the back cover off the laptop n disconnected the battery, after 3 attempts of the bios password it comes up with "invalid password", theres no number that comes up and none of the keys do anything, if anyone could help me out with this problem would be greatly appreciated, cheers
