How to determine what bit version of Vista was installed on a laptop


  • I am trying to fix someone's computer for them and it looks like I may have to install Vista on their system. It is a Sony Vaio VGN-TZ330E, and I was working with them as they were trying to fix the issue but so far no luck. Someone fixed his computer before a few years ago and installed XP (though the system hardware is configured for Vista) and some of the drivers won't install onto the computer. The issue that I am having is that the audio doesn't play back on DVD's, but will play back if you use MP3's, wav, etc. and I tried playing the DVD on a different computer and the audio works great. So am I to assume that the windows is the issue that I am having? Also what version of Vista Home Premium would I use x86 or x64 the sticker doesn't say on the laptop. It is an Intel Centrino and XP x86 is installed on the system now. If anyone can please help me out this would be great.
