- OK, from your description I think it could be either:
-
- 1) a damaged CIA chip (CIA-A or CIA-B)
- 2) a virus
-
- Try running Virus_Checker v6.51 over the system.. see if it picks up
- anything nasty. Failing that, try replacing one or both CIA chip(s).

- I still think it could be a problem with CIA/A or CIA/B. Maybe one of
- your expansions shorted the CIA chips?
- Are you still using the standard A500 Power-Supply? It could be that all
- this extra stuff you've got overloaded the PSU, and shorted the CIAs?
