Windows Vista Startup problems

[vspk17]

Hello

I have got a HP dv5t-1000 Laptop running 32 bit Windows Vista SP1. The laptop now won't start up. After the initial boot screen, a black screen appears and stays forever. I have tried running the boot checks (HDD an Memory) as well as tried loading using the system recovery CD supplied with by Vista. Nothing is working out. Can somebody give me suggesstions on the resolution?

1) Use the vista DVD to go to the repair mode.
2) From the same screen where you do the system restore, there's an option to open an administrative command prompt.
3) That should open in X:\Sources or something like that
4) Go to the windows drive by entering C:
5) Now go to the windows event log folder on your machine (C:\Windows\System32\winevt):
cd c:\windows\system32\winevt
6) ren Logs Logs_bad
7) mkdir Logs
This will create an empty folder for new event logs.

Restart the system and check whether you can log onto vista.
