John, how many RAM modules do you have? If more than one, remove all of them, and only reseated one. If that does not change anything, change it over to the other one. Try to restart with only one stick of memory. Remove the battery, the power supply, and the RAM. Now replace them again in reverse order, and turn your computer back on. Since I do not know what BIOS is in your computer, it is possible that this is caused by a faulty video adapter, but the POST code for that is 2 beep, pause, 1 more. Try an external monitor and see if that shows anything. Let us know how it is going. Good Luck.
