Solved the images on my monitor are too big, how do I change it back?

yesterday my pc rebooted itself and when it came back up all the images on the monitor were too big, I went into Appearances and changed it back to 100% but it was still much bigger than it was before the reboot, I reduced the size of the icons but the start bar is still way too big and when I open a browser, my tool bars take up half the screen. I tried a system restore but it didn't help any ideas?
Thanks

Hello ksimp, and welcome to Seven Forums.

You might check to see if your screen resolution is still set to the native resolution for you monitor, and that Magnifier is not currently running and making things look bigger.

Hope this helps,
