Check if your ram is getting power if so, Preheat the board in the oven @275 for 5 min then put lots of flux and reflow the ram. If the Ram is not getting power, Investigate that.

Voltage on L7430? If 1V35 is ok then probably corrosion under RAM or CPU. Or someone fucked with it and knocked off component around RAM/CPU area.
