If I remember, that would indicate that some of the socketed chips have loosened. Just take the top off, unplug everything, wear a static wrist band, and press firmly down on the chips and that should generally take care of the problem. Good luck.

    * Yellow: The CPU has found an error before the error trapping software (Guru) has been activated.

These problems could be caused by a number of things such as a loose chip or board.

Like others suggested, it could be a lose chip.. It could also be your memory expansion, so try to remove that as well. I had something similar happen with a amiga i saved from the trash, the battery on the memory expansion had leaked and destroyed the expansion board. If it is a a500+, the battery will be located inside the computer so then it could be alot more damage.

I removed the memory expansion and it's now working fine , if the problem is the battery can I change it?

Thanks guys for the help

The expansion card should in most cases work just fine without a battery, since it is only used for keeping the time when the amiga is powered off.
What you can do is check for any leaks and then try to clean it off carefully and removing the leaking battery. If this does not work, then the memory card has most likely been damaged by the acid.

Good luck! And btw welcome to amiga.org
