Hi I wonder if anyone can give me some helpful advice. I have a Toshiba Satellite Laptop that is giving me lots of problems, the computer seems to start I can see the led light turn green and can hear the hard drive workingm but there is no Display on the screen and when I try hooking it to an external monitor nothing comes up either. I tried switching the memory modules see if that helped but could not get anywhere there, I hope someone can help me out. Thanks for your time...
