Hi Tony--
The 7F stop error usually means an unexpected kernel mode trap caused by
failure on the MOBO or related hardware like a loose or misplaced RAM stick.
Usually when you see this BSOD, you'll see a *process exception code
displayed and the importance of it is that it pinpoints the cause of the
stop message. I'm inclined to think your error is a hardware related error,
however you have everything to gain by trying these:
***Startup Repair from the Vista DVD***
How to Use The Vista DVD to Repair Vista (Startup Repair is misnamed by the
Win RE team and it can be used to fix many Vista components even when you
***can boot to Vista):
http://www.windowsvista.windowsreinstall.com/vistaultimate/repairstartup/index.htm
If you elect to run Startup repair from the Vista DVD (it can fix major
components in Vista--I've verified this many many times; it's good for more
than startup problems, and the Win RE team simply screwed up when they named
it not understanding its full functionality):
Startup Repair will look like this when you put in the Vista DVD:

You run the startup repair tool this way (and system restore from here is
also sometimes effective):

How To Run Startup Repair In Vista Ultimate (Multiple Screenshots)
http://www.windowsvista.windowsreinstall.com/vistaultimate/repairstartup/index.htm
It will automatically take you to this on your screen:
http://www.vistaclues.com/wp-content/uploads/2006/12/click-repair-your-computer.png
That will allow you to go to the Vista setup that has a Repair link on
thelower left corner>click it and then you'll see a gray backgrounded list
and I want you to click Startup Repair from it and follow the directions.
The gray screen after you click the first link in the above pic will look
like this:
http://www.windowsreinstall.com/winvista/images/repair/staruprepair/Image17.gif
Click Startup Repair, the link at the top and after it scans>click OK and
let it try to repair Vista. It will tell you if it does, and if it
doesn't, try System Restore from the Recovery Link on the DVD. If these
don't work booting into Safe Mode by tapping the F8 key and using System
Restore from one of the safe modes besides VGA may work. That means you
have the option to try 4 different safe modes to get to system restore, (one
from the Recovery link on the DVD) and sometimes one will work when the
others won't.
You could also try a Repair Install with Vista which is done exactly the
same way as in XP:

***Using the F8 Environment***
***Taking Full Advantage of the F8 Options (Windows Advanced Options Menu)
by starting the PC and tapping F8 once per second when the firmware screen
with the pc manufacturer's name shows a few seconds after restarting***:
The F8 options in Vista are the same as XP, and the link for Safe Mode Boot
options is labled XP by MSFT but they are the same for Vista (they haven't
updated to add Vista to the title as they have with several MSKBs that apply
to both).
Again, pressing F8 repeatedly when you seem the firmware screen may be is a
generic way to launch Windows RE on some OEM Vista computers.
You could also:
Think: I have 4 different ways to get back my XP at F8 and try 'em in order.
1) Safe Mode 2) Safe Mode with Cmd to Sys Restore which is simply a cmd
prompt in safe mode 3) Safe Mode with Neworking 4) LKG or Last Known Good
Configuration
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

Frequently Asked Questions Regarding System Restore from MSFT:
http://www.microsoft.com/technet/prodtechnol/winxppro/plan/faqsrwxp.mspx
System Restore can be run from the Win RE recovery environment from the same
link as Startup Repair, and sometimes it will work from one F8 safe mode
location or from the Win Recovery Environment when it won't work from other
locations.
