Pat the cat thank you for your post
It hasn't been recapped before.I checked the capacitors they look ok,no bloated ones but i know that caps may look all right but can have serious issues,i would have to remove them and check the esr but maybe this would be the last measure if all else fails.
Now that you mentioned the power supply : i always had the stock even when i got the apollo card.They never told me to stop using it from the shop i bought it (and it was an official reseller shop of commodore products along with official service for commodore products).
I also had an external tower with a harddrive and cdrom but those got power from another psu on board the tower.
I remember back i used to have a different 68040 library.Now i only have the stock one from the workbench installation a 68040.library.i thought only the 68060 needed to have a different specific library?
Also regarding games i only use whdload ones and the most recent version,i dont play games that are not in the whdload format.i know that many of them could crash or i would have to change the arguments.
So it seems that the problem must be the psu.It seems that it cannot supply the current the cpu needs and then it starts crashing.
But i am amazed that i used it for many years back in the 90ies with the stock one.
I will also try to remove the floppy drive .
Which library of 68040 should i install?
My workbench is stock i did not install anything else only the latest version of installer from aminet and then i installed whdload,nothing else is installed (besides the games of course) it boots up very fast with all chip memory and fast memory free,and i can play any game i want from those installed.
