Main Driver:vga.dll
Okay, this means, you need video card drivers @.@
Do you have a NVidia video card? Go look here for a driver:

http://www.ati.com, then Support & Drivers.
Oh well, I'm sorry that I can't really help you, but without the name of your video card, there's pretty much nothing I can do..
Well, usually when you get/buy the computer, there are driver CDs with it. So you should look if you are able to find them.
Disabling sound in the setup menu didn't help? I know that solved this problem in the past. It seemed weird to me since it's a graphical fault, but eh. You may want to see about getting a video card, cause that's an onboard one, and bad at that.
vga.dll means: Windows uses its "worst" driver, just to be able to print something on the screen. VGA usually (or all the time) means: No driver installed.
EDIT: Just for clarification. It's not a problem about getting RO to work, but a problem about your computer and your video card. But WHEN you got the video card driver once, you'll most likely be able to play RO without any errors.
