Hello, You could try shutting it down and when you start it up press F8 repeatedly until you get a screen with the option to boot to the Last Known Good Configuration. Try this first and see if it makes a difference. A second way to get there.
Start Menu->All Programs->Accessories->System Tools->System Restore. Choose the most recent date before the encountered problem. If it doesn't work, try the next date.
To get a good accurate answer give the brand, model number, installed operating system of the laptop when asking a question as all PC's are not the same. Hey, I enjoyed your question, I am a retired computer technician. I hope I have helped you...
