Try any of the solutions below if some of it works. Make sure VMware tools is Installed or recently just Installed. if not you may reinstall your VMware tools once again before performaing any of the steps below.
1. If your host computer's screen resolution is high enough, you can enlarge the window, choose Fit Guest to Window to deselect it, then choose Fit Guest to Window once more to select it again.
2. If your host computer's screen resolution does not allow you to enlarge the window enough, do not use Fit Guest to Window. If it is selected, choose it again to deselect it. Then set the guest operating system's screen resolution to 640 x 480 or larger.
3. Inside of the directory where your guest operating system is stored, there is a file with a name like guestOS.vmx. While your virtual machine is not running, open your text editor (wordpad or notepad) and configure the (svga.maxWidth = "your number") and (svga.maxHeight = "your number") and start again your virtual machine.
