Ok so recently I had this issue with my computer:

I fixed that issue by removing the motherboard battery and reseating the RAM a couple times. Computer worked fine for a week or two.

Now I am starting to get the issue again, where the computer wont Post. Only way I can get it to Post is by again yanking out the battery and reseating the RAM a few times in various slots.

Anyone know what could be causing this?
