I've been a home computer user since the days of MS-DOS. Despite Vista being one of the less popular operating systems, I've not had a problem with the Home Premium edition preloaded on my Dell XPS420 since buying it 18 months ago. In fact, it's functioned flawlessly.
Unfortunately I couldn't leave things alone and when a friend with an MSDN subscription offered to download the Ultimate version for me, I gratefully accepted . Although the installation seemed to complete OK (the upgrade option was greyed out so I did a clean install after a back up), disaster struck when the machine rebooted. Virtually NOTHING works. Trying to install the driver for my Nvidia 8800GT graphics card results in the BSOD, basic programs like Adobe Reader generate countless error messages, and even Internet Explorer crashes after 60 seconds at most. In fact the only programs I can get to run are a freeware disc burning suite, and Firefox - although the moment I try to install any plug-ins, that crashes as well.
I can't reinstall my old Home Premium (OEM) either, there is a partition on the hard drive containing a restore option but a message appears saying "Access to tools\dp.sc was denied".
Anyone got an idea as to what is wrong? The software my friend downloaded was not the Checked/Debug version so I can't figure out what the problem is.
Thanks in advance
Forgive me if I occasionally ask silly questions. I'm only human!
