|Your problem has got nothing to do with the computer being off for two weeks.|
Video drivers do not spontaneously get corrupted.
Something else must have changed.
"main concern is the adjustment bar usually at the bottom of the screen to go left or right has disappeared."
I have no idea what you're referring to.
Do you mean the Taskbar on the main desktop screen ?
- or - do you mean the bar at the bottom of the page in Internet Explorer ?
Windows has a full screen display mode.
Some people don't know about it.
When that's toggled on, when you have certain windows open in Windows itself, the bar at the bottom of the screen disappears .
When that's toggled on when you have a window open in Internet Explorer, the bar at the bottom of the screen disappears, and all of or most of the bars at the top of the screen disappear, but will appear again if your cursor is close to the top of the screen
You press F11 to toggle full screen display mode on / off .
"font size and icons are too large."
If this is a desktop computer, have you changed which monitor is connected to the computer ?
If yes, if the specific drivers that have been loaded for your video adapter don't recognize the monitor properly, Windows' Display Properties may automatically use a lower resolution, and in that case the icons on the screen and the text on the screen will be larger.
RIGHT click on a blank part of the main desktop screen, choose Properties (goes to Display Properties)
Click on the Settings tab.
If it says unknown monitor or Default Monitor on (the name of your specific video adapter) , you must change the monitor type to at least Plug and Play Monitor.
