rashed,
Did you have a chance to test the laptop with an external monitor attached to the VGA port? Can you get video on the external monitor?
First of all, I would check memory modules. It’s possible that one of the modules failed.
1. Try reconnecting memory modules. Remove them from the motherboard and install back in.
2. Test your laptop with each module installed separately. If one of them is faulty, the laptop will start when the bad module is removed.
