Mac book Pro late 2008 - restart and kernel panic - need help!

Hi,
I really need some support from the Mac community. Here’s my problem:
I own a Late 2008 Mac Book Pro serial W88492RM1G0, 2,4 GHz Intel Core 2 Duo, 8 GB DDR3 a 1333 MHz ( I upgraded the RAM few years ago, originally mounted the 1066 Mhz), NVIDIA GeForce 9400M 256 MB, 1 Tb Fusion Drive with 550Gb SSD and 500Gb HD.

It worked fine until 1 years ago it started having serious issues of power supply. The input of the power supply became very hot, and the Magsafe did not worked properly. The pins were stuck. I changed the Magsafe, but the new lasted few months then started again.
I changed the input on the computer but still it become very hot

Then bigger issues came up:
it freezes if I move it, or even alone, and then shows kernel panic messages.
it restart from nothing, when I work
Sometimes it does not restart and when restart there’s a beep message: 3 long beeps and 3 short beeps. It stops only if I force the shutdown
Sometimes it shows the wrong way sign, once even a half apple.

Please advice on what is the issue, and how to solve it. I’m considering buying a new one, of course, please do not waste our time with such advices. I spent 300€ on new SSD and other works, I ‘d like not to lose that money.

Thanks from the core for your help

Tommaso

    Probably EFI ROM corruption, but the "half-apple" suggests a deeper hardware problem. Apple used to have a boot CD to download to fix this, but I couldn't find it with a five-second google search

    The 2009 and later will fix this automatically, for what it's worth, but that doesn't help you.
