OK I am going to step in and try to help you out onedaysoon.
It is obvious your OS has become corrupted, now the quest we have here is recovering it and getting it back to normal again.
I have to start by thinking along the line, that you have disk errors and we need to work together on fixing those errors.
I need to ask if you what type of media your operating system is on. (The operating system installation media)
The options are:
1--It is on a Sony OEM system repair CD.
2--You have a Floppy disk version "system repair diskette" which boots and looks for the OS installation files on a hidden harddrive partition.
3--Or you have it on a Microsoft Windows XP cdrom.
The repair options we have here depend on what media you have that I listed above. I need to know that answer before giving you any ferther advice.
Oh and one last question, I am looking up your model number at sony's website, I see a model with the model number VGN-T140P is this number on your laptop?
I will keep my eye on this thread for your reply.
