the remove programs feature in control panel shouldn't contain anything that could do as you describe to your system, it's really there as another way to uninstall programs you've put on you pc.
I suppose it's possible you deleted the drivers for your graphics card. These arn't used when you first boot up so you'll see the loading pages as you pc post's and you'll get the option to enter the bios set up page ( del ) and the option to press F12 which is other boot options.
try pressing F12 and selecting boot into windows safe mode with networking, see if you can load into windows that way, It'll load only basic and essential drivers and programs. You could from here use system restore to revet you pc back to a time when it was working properly. This is something of a stab in the dark though, if you could post up some more details of your pc and any error messages or beebs you hear we might be able to provide a better and more accurate response.
