17" powerbook

ive had my good old 1GHZ 17" pbook for 2 years now and only yesterday i closed the lid, opened it later and the computer wasn't on. I turned it on and the screen started showing odd colours and shapes. Later i turned it on and the screen didn't work. I then turned it on again and it started in open firmeware and said 'invalid memory access' and lots of wierd numbers. i shaked it a bit and i heard a rattle. i opened it in to discover a loose screw, i put it back in, same thing. i took out the RAM chip blew it put it back in, turned it back on, turned on normally and then a kernel panic. i blew the RAM again and turned it on and said 'invalid memory access' again. Can anyone explain this? do i need a new computer?

have you tried booting without that ram chip in at alll? it may be bad ram, is it new?
even if its not, it could go bad.

yeah I would for sure remove that ram and boot again.
