I suspect something is wrong with one of your drivers but you can try this. Restart your computer and just before Windows starts press the F8 key select start normally, if that doesn't work restart your computer and choose Last known good configuration. If niether of these work and you are still in safe mode goto the Device Manager and look what driver is not intalled properly (has an X, ? or ! beside it.
To get to Device Manager Right click on My Computer (either on your desktop or in your start menu) click on Properties and click on Device Manager.
