Find 32-bit or 64-bit system type if your computer does not start

If your computer does not start, you can find the 32-bit or 64-bit system type from the product packaging. You can also find the system type online from a product specification document. Search the Internet for your computer model and the terms "specifications" or "review" to find webpages that list product information about your computer.

From any Web browser, search the Internet for your computer model number, a space, and specification.

For example, if you own a TouchSmart 600-1055 computer, type touchsmart 600-1055 specification.
Open the specifications webpage from the list of search results that matches your computer model. If you have an HP computer, be sure to open the page from the HP website.

A product specification support document opens.
Scroll down to the software section to find the operating system version and system type.

The system type is listed with the name of the operating system, for example: Windows Vista Home Premium (64-bit). If 32-bit or 64-bit is not listed next to the name of the operating system, the system type is 32-bit.
