Sp1 vista ultimate update error!

hi
i updated my computer (vista ultimate) with the service pack 1 update. i left it to update and when it reboots it updates the files on the black screen. it got stuck on the file ( ! ! 0xc190036 )(Dxgi.dll). i left it on all night and still no luck, so i tried to go into safe mode but after loading a load of files it froze on chkdsk.sys. ive tried to run it in other ways but still no luck and if i try last known good configuration it comes back to the loading files for the update screen and again gets stuck
please help , i contacted windows around 4 days ago and they still havent replied
thanks !

There are a LOT of different people having this same problem, but their issues were caused and solved by a variety of factors...

Your best bet would be to google "CRCdisk" and browse through the results, see if anything fits your situation enough to try.
