Commodore 128 Update

I opened my C128 last night and reseated all the socketed chips, I though this might help with the odd lockups and the machine code screen dumps I have been getting. Unfortunately, this made things worse, I am now getting a black screen when I turn on the power, even C64 mode does not work. Additionally, when I press the reset button it does reboot, but I get an odd tone for several seconds. Looking at the troubleshooting guides, there are a lot of things that cause this and at this point I do not know if I screwed something up, or I simply accelerated the failure of an already ailing computer. The next step is to open it up again and reseat the socketed chips again, and make sure I did not do something wrong.
