As Jon says have you tried Startup Repair? How about the Bootrec.exe tool
in the Win RE environment?
Also before the fat lady sings, you need to exhaust every safe mode to
attempt to run System restore from the F8 Adv Options menu after you try
those including to run system restore from the command prompt. Sometimes
running System Restore from one safe mode works when others don't. In my
experience SR from the Recovery environment works better, but not all the
time.

I'd deploy these if replacing the driver (provided you can boot) doesn't
solve the problem:

the Lock button, and then click Restart.
This usually means that you enter bios setup by whatever key or keys

pc manufacturer site) and configure CD to be first in the boot order.

3) Select your OS for repair.
4) Its been my experience that you can see some causes of the crash from
theWin RE feature:
You'll have a choice there of using:
1) Startup Repair
2) System Restore
3) Complete PC Restore
You could also:
Try to F8 to the Windows Adv Options Menu>try 3 safe modes there (I don't
use WGA) and Last Known Good>then I go to Win RE in Vista. That gives you a
choice of Safe Mode, Safe Mode with Networking,and Safe Mode with Command
Prompt.
These methods are outlined in
A description of the Safe Mode Boot options in Windows XP/and Vista

You will need this reference:
How to start the System Restore tool at a command prompt in Windows XP
http://support.microsoft.com/kb/304449/en-us
The command to use for system restore at the safe mode cmd prompt is:
%systemroot%\system32\restore\rstrui.exe
The reason for doing this is one of these choices may work, when the other
doesn't. My experience is that people do not fully try F8 when they think
or have said they have. It is that they can almost always reach Windows
Advanced Options though.
Good luck,
