How to Set Studio One Dell Desktop Back to Factory Settings?

So I'm running Vista in my computer and I've been looking for the past 3 days how to set it back to Factory Settings but nothing has worked. I tried F8 and it brought me to the Advanced Boot Menu and all it had for options was this:

Safe Mode
Safe Mode with Networking
Safe Mode with Command Prompts

Enable Boot Logging
Enable Low-Resolution Video
Last Known Good Configuration
Directory Services Restoration Mode
Debugging Mode
Disable Automatic Restart on System Failure
Disable Driver Signature Enforcement

That is basically exactly what it looks like. I watched a video and usually at the top it has "Repair Computer" but my computer doesn't even have that option. So I tried Ctrl + F11 and that didn't do anything.

My computer came with two disks, one for the Drivers and Utilities and the other is for the Application. I don't know if I should just...try sticking those in if it'll do anything but I could try. Does anyone have any other ideas before I start sticking random things in my computer?

Also, I'm only setting it back to factory settings because I can't do anything else for it. It started with Youtube not playing videos, so I used System restore to see if it was an update that ruined it. Temporarily it played Youtube then it broke again. So I did another system restore and it broke my Audio driver forcing me to reinstall my audio driver. Then anything that ran Java didn't work in Firefox and Google Chrome didn't work at all. So I was forced to use Internet Explorer. Just so you know I'm not doing this because I have a virus, hehe.
