how can i fix errors 00173, 00301, 08611, 001163?

When i turn on my thinkpad 600e, this writing appears on a black screen :

' 130496 KB OK
161
8611
163 '

Once that has appeared, it tells me to type in my password, i do and it fails to accept it. Although if i press the enter key, it comes to a screen with a green box on which says error and has these numbers on it : 00173, 00301, 08611, 00163. I cannot go any further than that. When i turn it off it just repeats the same process.
Please can you help me?

Confused!
