Make sure you have all the graphics card drivers installed and are up to date.

if you installed mod-killmarks or anything like that .. or even a program, try unistalling it or refering to the old one
Lol all these people saying reinstall CF, run CCleaner, reinstall windows.... it's clearly something to do with your graphics card/drivers.
Something you could try is right click desktop -> properties -> settings tab -> advanced -> troubleshoot tab and turn hardware acceleration down a bit and keep turning it down and see what happens. CF may not start at all but it's worth a try.
