Here are you specs for your HP G61-110SA Notebook Computer. Here is the HP Software and Driver Downloads page for your computer.
You should have created your personal set of Recovery Discs or recovery media when you first setup your computer. If you didn't create these discs, you will need to order them from HP, if they are available. Please contact HP in your region or country via the HP Worldwide Support Portal.
Alternately, please see "How to Install Windows 7 Without the Disc" for instructions on downloading Windows, creating installation media, and installing Windows 7 using the 25 digit Microsoft product key on the COA affixed to the bottom of your computer. Please note that you will no longer have use of the HP included "value-added" software that originally came with your computer.
