Vista upgrade fails

[Guest]

I am trying to upgrade from windows xp pro sp2 to vista ultimate. I have
uninstalled my antivirus , firewall and graphics card , and upgrade advisor
says everything else is ok. I have also updated the BIOS on the motherboard
and as far as I cna tell turned off all features of shadowing chacheing etc.
When I try to run the upgrade from it gets to about 52% in the completeing
upgrade stageand then restarts. It then loads for a bit before crashing.
Oninvestigation the following stop code is produced;
0x0000007E (0xC0000005,0x81890762,0x82ceea68,0x82cee764)
Anyonr any idea what might be causing this? All help much appreciated.

Sounds very much like a driver incompatibility -- often the upgrade
adviser doesn't predict these very well. If you are attempting to
upgrade over your existing XP partition you might have better luck
with a clean install to a new partition or even a new disk. This is
perfectly legal even for an upgrade version -- just install without
entering your key and activate with your key only after you know that
all is well.

Don ,
Thanks for that I was kind of thinking I might have to go down the new
drive/partition route was just hoping there was another way!
