Could be a bad motherboard. Try different RAM and working without the battery see if that helps at all. Aside from that you need to start testing hardware like the motherboard, sometimes a bad hard drive can cause a crash and inability to boot also.

Did you check with an external monitor? LCD could be bad. If an external monitor also does not work, it's likely a motherboard issues but you can test different RAM first to rule that out.
