Just checking, as we're already on page 3 now and I don't see any progress. Have you done any of the MANDATORY FIXES or BASIC TROUBLESHOOTING yet?
Got a new exxos PSU so that's fixed already
Not using parity SIMMS
DMA pull up not needed because i'm not using a hard drive and no floppy drive (or does a gotek also count?)
Same for the 1772 pull ups because gotek
Pressing the reset button on startup doesn't fix my problem, so that reset circuit is also not the problem
Then I just need to recap the video circuit, and fix the bus resistors, don't know if those can cause the problems I'm having, but I'll do these fixes!
But what I find weird, is that I've only had these problems right after I did the 4mb update, so I keep thinking that caused the problems I'm having, instead of common ageing problems (unless that bad update could have caused one of those problems in that mandatory fixes list of course)

I'll also try using the freeze mist @PaulJ!
