When was the last time it worked without these issues? Have you attempted a system restore?
Which operating system are you using?

Do you have your model number to hand please so i can do some research please? 1st of all you need to check make sure your monitor is plugged in proberly if this is a desktop im assuming it is. If you have a vga lead then you may need a new cable. Then check your ghz you may need to change from 60 to 30 under the monitor adapter settings.
Let me know thanks.
