I am trying to install Vista on a new PC with a MSI P45 NEO
motherboard and an ASUS Radeon EAH4850 graphics card.

I have had several installs that have failed, usually with BitDefender
antivirus. I have now done a clean install with no additional software
and only the drivers that did not install automatically (LAN, graphics
and Intel).

However I still note that Internet Explorer occasionally crashes. For
instance if I search from the msn.com start page for “test vista” I
get a link (probably because I am in Holland) to
http://www.computable.nl/artikel/ict...ystemen/236273....

That URL (and many others) crashes Internet Explorer, but the (MSN
search) cached link doesn’t.

Is this okay and should I continue installing, or is there some
problem with my PC. Could it be hardware? I have done memory and HD
tests and found nothing. Another possible cause of the previous woes
could be that I have large D drive full of data from my previous
machine. The "owner" was of course some unknown registry key. Could
that have caused problems when installing e.g. BitDefender?
