How can I fix my Acer Aspire 3680?

I have a Acer Aspire 3680 that I bought about a year or two ago. I'm trying to wipe out my computer because it somehow got infected. I've had this problem before and relaized that I had to buy the back up disks considering Acer doesn't provide them when you buy the computer. I wiped out my computer with these disks before and it worked fine but I can't recall how to run the CDs. I put disk one in but all I can bring up is the folder. Is there something I need to push when my computer is starting up to get it to run?
