another nightmare, I have upgraded my cpu on the xps 420 and it booted up ok after the first time I upgraded cpu, I also upgraded the graphics card and then added the latest drivers from nvidia website, I then though that I had not applied enough thermal paste so cleaned the cpu and took it off and the reseated the cpu back, then the nightmare of windows vista just goes to the post screen with the green bar at the bottom and the bar only moves slightly and the screen goes blank and I see the blue screen but cannot amke out the information as it restarts immedietly, it then gives me an option of recovery or normal mode, if I click on normal mode it does the same, if I click on the repair it loads up and gives a few options like repair which it does and the states that windows could not fine any probs, I have also used the restore but to no avail, I have also tries this repair from the dell vista cd, and when I goto repair it does the same stating windows cannot repair as no problems have been found, I can see everythig on my hard drive inc all programs etc when I click on the backup option on this and also x drive (which aprt from the dvd and the c drive is also there) I have chkdsk/r but nothing it still does the same thing, I have then changed the cpu to the same one and also the graphics card to the 2400 pro but still exactly the same, I donot want to reformat the drive as I have vast amount of updates I had loaded from microsoft and also a lot of work, is there any help on this, I have also taken the drive out and added a new drive and installed vista no probs, it is working, please could any one help on how to fix the first drive without reinstalling windows vista. I have also done all the diagnostics etc for the whole system tand everything is in working order inc memory which I have downgarded to 2 gig

Anytime hardware is added or removed in the computer, the BIOS need to be updated, usually by pressing F2. Any additional settings, clock speed, and whatnot need to be set in the BIOS, first.
The BIOS is like a brain of sorts, in telling how the components are to be used in computer system.
With RAM, usually all that is needed is to open the BIOS, see that the RAM is indeed loaded, save and then exit.
With hardware changing, especially CPU, correct parameters needs to be entered for the new CPU.
If you have used Arctic Silver, make sure there is no residue that had gotten pushed out and on the motherboard. This compound is conductive and can short out if touching the motherboard.
In fact any thermal compound should never be touching the motherboard. Power the system off, and use a Q-tip with 50% alcohol solution to clean up any thermal compound that may be exposed.

try to boot vista in save mode,
delete all drivers related to the 88ultra and all n-tune software as well
best is to use drivercleaner or simliar.
restart vista and install the drivers again.
if this will not help give me a few minutes to check my own xps 🙂
got nearly the same issues with my 8800GTX but not sure what was the final fix 🙂
p.s. check all cables to the videocard as well and that the card is well locked in the pcie port.
ok try following steps:
1. boot and press after the dell logo many times F8
2. blackscreen comes on, you choose safe mode only, there are other options but choose the first safe mode only!
3. Windows starts without the most drivers so you will have a poor grafik and maybe no internet but its ok
4. uninstall all ati and nvidia software
5. restart windows and check if all working as before
6. install nvidia drivers again
this should fix it.
remember to press often F8 while booting
Hi just got round to trying the f8 and yes it does give options for safe mode but it only loads up so much and then same thing happens again and it restarts automatically, also manage to get the blue screen error codes they are STOP: 0X0000007B, 0X30399BBO, 0XC0000034, 0X00000000, 0X00000000
Is there anything that you can make from this info
now its going a little bit more complicated...
i know that the stop code 0x07b means inacsessible boot device
means no boot from this hdd possible.
can be an issue with the MBR.
did you try the "fix mbr" option?
