Hello all this is my first posting:

I have a HP m8200n computer using Windows Vista, recently i tried to upgrade to the Microsofts SP2 update, then a power outtage happened, now the computer won't reboot entirely.

I am getting a message for nvlddmkm.sys after a crash dump it restarts and i can never get back into the login screen for my username.

Can someone please help me with this issue.

I also cannot use safemode it just keeps restarting, can i modify the bios or something?

any help is greatly appreciated.

Given the fact you were in the process of a system update when the outage happened, your only choice appears to be to do a full system restore using the CD's your computer came with. The nvlddmkm.sys is a Nvidia display driver that in its own could be corrected but if you can not even get into safe mode. I recommend the system restore.

is it possible to just get a new graphic card can that also solve the issue?

       There is a good possibility that a new car may fix the issue but it could also be your motherboard that is having trouble. Do you have a graphics card in the unit now?

The orginal graphic card is the computer right now.  The problem is that I cannot get back to the username login screen.  Everytime i reboot it does a crash dump, is the only possible solution is to do a clean system restore?  or is there another solution.

   Unfortunately yes, you does your motherboard have a integrated graphics card if so you may be able to remove your graphics card and plug into the integrated. That may be able to get you to the OS aso that you can see what is causing the issue. If that works then you may be able to get a new graphis card and it may work.

Replacing the video card will do nothing for your issue. So long as Windows keeps trying to startup using a corrupted driver it will never start up to install the new video card drivers. Its not your motherboard or your video card. Its a driver issue and since you cant get into safe mode to correct it your only option is to do a full system restore.

That's a lot of work. It'd be easier to boot using a linux disc and get your data burned onto dvd's and then do the restore. It'd be free and you don't have any way of knowing whether or not a different graphics card would work. For all we know it could be your entire windows system folder that's corrupt and nvlddmkm.sys is just the first file that's causing a failure. Heck, you could try booting into linux, extracting from the exe or getting a copy fo nvlddmkm.sys from drivers for your card, and then copy it to your windows system folder and see if that fixes anything. Any way it goes you're going to want to do a full system recovery at some point or another.
