|weird that the Control Panel (Add/Remove Programs, right?) would let you uninstall anything critical to functionality unless it was drivers.|
so, can you boot into Safe Mode? Power off, leave it dark for about 30 seconds, power on and tap F8 until you see a list of boot options. Choose Safe Mode.
If you can get into Windows in Safe Mode, you removed a required driver. Go to Computer Management, Device Manager, and see if there are any hardware devices with a yellow triangle. Reinstall drivers for this component.
