A500 failing?

What does the system do without the extra ram fitted?

The next step would be to take the A500's case apart and look over the motherboard for any signs of damage. Blown capacitors (the tops would be bulging up slightly rather than flat), and also make sure all of the socketed chips in the system are well seated in their spckets by giving them all a gentle push into their sockets.

At the moment I would try cleaning all contacts on the Mobo with Isopropyl alcohol (especially the RAM expansion) and give the Mobo a good inspection to see if there's any visible issues.

Last night it wouldn't get past a blank white screen without the RAM. I tried it again this morning and it actually booted from my Workbench disk. It did complain about not having a clock backup battery or something. I will inspect the motherboard after work today.

The reason for the error about the lack of battery is because you have the Setclock LOAD command in your Startup-Sequence.

I ripped apart the A500 and inspected the motherboard. No leaking capacitors, no discolored parts on the board. I pushed down on all of the chips just to be sure they were seated snugly. Since I put everything back together I haven't had a problem, but I wouldn't be surprised if it's just playing games with me. Yeesh.

You may have inadvertantly reseated something!
If it still persists, I reckon you'll have to get ther soldering iron out (or you could take the lazy option and get an A500 mobo off ebay)

Glad everything's worked out for you.
