Hey Jorbish,
Welcome to PCHF, we have a wonderful team of techs here, and I am certain that we can get you up and running.
I laugh because that proprietary garbage makes me crazy too. You sound just like me.
I am assuming that you have the stand alone versoin of Vista, correct?
You will want to make a list of the drivers that you need, your vidcard, sound, etc. Your drivers should all be located in the C:\Drivers folder, make sure to burn this to a CD, along with the C:\Windows\Driver Cache\i386 folder.
The best way to do a clean install is to reformat the HDD and then do the install, however, you must be aware that this will wipe the partition that allows you to hit the F10 key and take it back to factory specs. I would make sure that I had the recovery CDs just in case.
Also, Sony tends to use a Shared Library, and other programs that some drivers such as your sound may be dependant on, you should be able to find all of the original drivers and updates here
Sony Support.
Looking forward to your reply,
TTFN
