Ubuntu :: Monitor Turns Off After 10-15 Minutes?

I've read many posts about other people having this issue and I can't seem to find one that is the same problem I am having. I'm totally new to ubuntu and linux as well for that matter, Basically I wanted to give linux a try and started doing some research and liked everything I read about ubuntu. I went to the website and used the wubi (I think that was what it was called) to install ubuntu. Now when I boot my computer it asks me which operating system I would like to use. I navigate to ubuntu and press enter and it starts up with no problems what so ever.

At first I was really surprised with how easy the installation was and how great everything was going, however. After looking around for about 10 minutes, the screen abruptly went black and then my monitor had a small blue box on it with "No input" on it before the light went from blue to orange. I tried hitting every combination of keys I could think of and in the end had to do a hard restart.

Long story short. every time I use ubuntu my monitor shuts off after about 10-20 minutes, regardless of what activity I am doing. I've tried going to /apps/gnome-power-manager/timeout/ to make sure that sleep_display_ac was set to 0 (it was), I've turned off power management using the power manger under preferences. No matter what I have tried, it continues to be a problem.
