In this instructable it will only go up to medium.
Step 2: Upside-down Screen (Easy)
A virus may have caused you computer screen to flip or a toddler may have just been messing with your computer but it is fliped and you have no clue what to do. Call Geek Squad? No. just press Ctrl>Alt>Up (Down turns it upside down and Left / Right turns it the direction).
For some computers it may not work. I know it works for Windows XP. It works in my school's computer lab. I don't know if it works for Mac, Linux, or other brands. If it dosent, you don't have to worry anyway ;).
Step 3: No Sound (Medium)
Go to Control Panel.
Then go to hardware and sound.
After, click sound (No, not any of the other options, just Sound.)
Right click on the Speaker and left click on "Set as default device".
