Recently, my computer was frozen...I pressed ctrl, alt delete (I know I should not have but I did)...my computer began working but now the task bar and all icons have shifted 90 degrees to the left and are now in a vertical position. I cannot restore computer to a previous point to clear it and cannot find any way to shift it back to the horizontal position. This includes the cursor and everything. We have to lay the monitor on its side to view. Help!!! Any suggestions other than getting a new computer????
