Again as was stated before GET THE CODES PULLED!!! very very very important part of anyone helping is knowing what the exact codes are. If you go and start throwing more parts at it you may just end up wasting money, in a lot of cases the codes will help determine the exact problem and allow someone here to be able to help.

^^ What izzysplace says. You can easily go by all the posts that tell you "mine did this, and I changed <enter part here>". Doing this may eventually fix the problem, but at a very high cost.
