survival,
Here's a couple of things to try:
Power down and remove the battery. Leave it out until you are done with the following procedures. Remove the memory modules and put only one back in. Try to power up. If that works, replace the other one and power up. If that works, you're fixed!
If not, try to power up in safe mode and see what happens. If it comes up, try running diagnostics on the HDD. If that fails, try reseating the hard drive.

Let me know how you're coming along on this. May be able to come up with more ideas, if needed.

If you need any additional information, please feel free to ask.
