Ok, well I won't be on skype for a bit cause I have stuff to do this weekend so I'll explain how to change the refresh rate.
Right click on the desktop, go to Personalize, bottom left corner select Display, Top left, select Change display settings, middle of the screen on the right side click Advanced settings, select the Monitor tab, and in that window it gives you options for screen refresh rates.
In this window you also see the Troubleshooting tab that the "help" window was explaining, if you select it, and go to Change Settings you will see the acceleration options.
