Does that help. The link doesn't show the taskbar disappeared.
I am currently having an issue where my taskbar is lower that the base of my screen, so I HAVE to drag it up in order to see it. It is sort of driving me crazy because I don't know what is causing it and the start button doesn't match the same level as the other buttons on the taskbar. I was reading online that it might be my video driver, and I looked into that and apparently mine is completely up to date. Also, I recently reformated my hd and reinstalled windows 7 onto it, in case that might help with solving my problem at all.
Please note, I already checked with messing with the resolution of my display and that is not the issue. I've always used this resolution and this is the first time I am ever having this issue with my taskbar too.
Here is an image example of what is going on (the red line is where the taskbar is cut off at the bottom of my screen that I cannot see): http://orig15.deviantart.net/56eb/f/2015/288/8/a/help_by_anticlimactic_geek-d9d8jlu.png
