How do I know if i have windows vista 32 or 64bit?

[brc3404]

My laptop will not load windows, i keep getting an unmountable boot volume blue screen of death. Problem is my laptop doesnt come with a vista cd or recovery cd. So i need to purchase a vista disc from ebay and Im not sure if my vista is 32 or 64 bit. Will either 32 or 64bit disc allow me to use recovery console? Or does it have to be an exact match? Im trying to avoid having to format and lose everything! Windows serial sticker says windows vista home premium OEMAct. Any help is greatly appreciated!
THANKS!

What Make/Model is this laptop?... maybe the model only came with 32 or 64 bit and you will then know which one it is. Another factor is how much memory the laptop has. If it came with less than 4GB then its almost always 32-bit, especially if 3GB in memory capacity from laptops i have worked with of that period.

Here is a link that shows another person who had same question a few years ago, although no good answer.

Patio and Allan. Windows wont load therefore I cant get into windows explorer unless you know of another way. Dave, thanks your info should solve my problem! I tried looking up the product/model and couldnt find anything on whether or not it was 32 or 64. Hopefully the ram spec will tell me which vista i need! Will follow up~
Thanks Again!
