if its a laptop and its the motherboard, its probably not worth the money to fix as you can't just buy a new motherboard and install it. if its under warrenty then send it back to be fixed, if now then you are probably out of luck.
You are right, It was the motherboard and I Bought a new one for $50.00 and put it in and everything is good. I was hoping it wasnt the mother board but i thought it was because they are usually not worth fixing. But this one worked out for me... thanx for your time. Elisa
