WinUAE: Green Screen
 

Toni with AROS 68k after a crash if I do F12 and run Restart/Start I get a green screen.

It is solved by repeating Restart/Star or by running Clear Disk history.

From what I can guess it's as if the RAM is still dirty.

I can not identify from which beta it started because it does not always appear, it seems that from beta 20 it is more frequent but it may be just a case.

From this page alone: https://en.wikipedia.org/wiki/Kickstart_(Amiga)

It looks like no Chip RAM has been found, or it is damaged.

Yes that's what I suspected, the strange thing is that it happens only with AROS 68k and only after a system crash, as said just do a couple of reboots or use the Clear Disk history.

I'm trying it on my other PC and it doesn't seem to happen, I probably will have some faulty RAM on that PC ?

Not likely. If the PC itself had faulty memory it wouldn't present itself in such a specific and repeatable manner without causing other much more obvious problems.

Make sure the WinUAE configuration is actually identical between the two systems?

In fact I did the RAM Diagnosis and found no problems. If it was really the RAM I should have had problems on other applications or other WinUAE configurations, I use a lot of them daily.

The configuration used on WinUAE is the same "identical", the only difference between the two PCs is that one has Win7 32Bit, the other Win7 64Bit. I used the same version of WinUAE 32Bit, but I can't exclude anything since the Green Screen doesn't appear always and appears only with AROS 68k !

There is a detail I didn't mention, every now and then I get a Blue Screen on Win7 and to restart it I have to remove and put back the RAM.

This could be a problem of false contact because it happens after many days, I must try to replace the RAM, although it remains a mystery because it happens only with the AROS 68k emulation, never had problems with AfA One or other Amiga OS that I emulate daily.

That explains a lot, and I think you should replace it, then test the replacement. I had a similar problem once, many years ago.

Yes that's what I'm going to do, I have two 2GB RAMs, at the next Blue Screen I'll try to replace one so I can locate the faulty one.
