Acer 5735 Black Screen

My Acer memory had filled and I was planning to transfer the files to an external storage. I never got the opportunity to buy and transfer the files to an external hard drive. First the computer died and I restarted it with a recovery disk. Then a few days later I was getting a black screen and the computer would not boot. The power light comes on , blinks once, and in a few seconds shuts down. I tried battery out and back in. I tried without the battery. I tried from battery only. I tried taking the battery out and disconnecting the power source. Then I held the power button for over a minute. I plugged back in and it didn't work. I put the battery back in and it didn't work. I bought a new power cord. I tried ALT F10. I tried cleaning the fan. I tried flash drive with new BIOS along with FN and escape while powering on and that doesn't work. I tried RAM out make sure it is clean and back in. I even tried superstitiously tapping the bottom as someone suggested. Nothing has changed. When I power on the light comes on, it blinks once and then after a few seconds the light goes off. When it blinks and just before going off the fan stops.
