Laptop BIOS passwords are kept in a special password chip. On some laptops these chips are replaceable and there are a number of places you can buy this. PWcrack.com for one.

This indicates a possible memory problem. Reseat the RAM modules and boot up, if OK then the laptop is OK.

If you have two RAM modules, remove both and insert one and boot up, if it is OK then repeat with the other one - this will determine which memory module is faulty.
