I am not very checked out on laptops so any help would be appreciated!

I was given a Pismo which has no harddrive,but my first problem is that when I turn on the laptop the screen is covered with about 50 horizontal lines about a 1/4" wide. When i first got the laptop it would start up with a clear screen showing the ? mark folder (no hard drive), but after I openned it up to check the boot problem, it began having the lines on it.

I sincerely would appreciate any help given!
