Do the lines on the screen appear as soon as you start the pc or only when it boots into Windows? Is there a pattern to the beeps e.g. does it go 6 beeps - pause -6 beeps pause etc?

What is the exact model number of your laptop?


The model is 5050-0705 and yes it does 6 beeps and then pauses


Yes lines appear as soon as i put the laptop on..

Unfortunately for you the 6 beeps indicate that there is a problem with the video unit in your laptop. This usually means either a replacement motherboard or possibly a professional repair.

A repair by a reputable, professional Dell authorized service centre may be possible but it will probably be cheaper to replace the motherboard.
