I've spent a lot on my Amiga's over the years and now i'm at a stage where I am having trouble making it all work. There is a lot of text here but please spare me some of your time to help me out here and make it all work as i'm losing my marbles trying to fix this lot.

A1200 Problems

System: A1200T, Mediator 1200 TX, Apollo 060 clocked to 66mhz, 64mb fast, Lyra 2 keyboard adapter, Indivision 1, DVD, two mechanical hard drives, Voodoo 3, Sound Blaster 128, Realtek NIC, floppy drive, IDE buffered interface, A2000 keyboard.

Before I added the mediator this system was working fine. However since adding the Mediator once Workbench loads up the majority of the time the keyboard will not respond when typing on it, occasionally if I open a shell or a text editor a random character is constantly appearing as if they key in question is being held down, sometimes the caps lock light will come on when pressed and sometimes it won't, Crrl+A+A seems to work everytime to reset the computer. I've tried three known good keyboards (1x2000 & 2xA4000), and i've tried it with WB 3.1 and 3.9 just to eliminate the possibility it's software related.

On the odd occasion it will power up and the keyboard works, i'm attempting to install the mediator software (i've never seen it working yet). When I run PciInfo it only reports one device attached and it does not know what it is. But when I only had the Voodoo 3 installed it reported that card correctly, then when I added the SoundBlaster it reported that card but not the Voodoo 3.

The power supply is upgraded as the original that came with the tower couldn't power the 060, i've attached a picture of the rating sticker to this post. Could this all be down to the power supply being inadequate again? If not what else could be the problem? I can't remove the 060 to test the Mediator as it requires fast ram at least to work so i'm a bit stumped as to what to do next.


A4000 Problems

System: A4000D(T), Cycberstorm II 060/50, 128mb on CS, 16mb on mainboard (recapped last year), Cybervision 64/3D & scan doubler module, X-Surf 100, two mechanical hard drives, DVD, floppy drive, zip drive, IDE splitter, Buster 11

This was all working fine using P96 but randomly I loaded something up and the system froze. When I rebooted the hard drive had SFS errors so I fixed that (I think I added some removeable drive caddies for the hard drives about this time but i'm not sure if it was before or after this problem started). Now I cannot get the graphics card working again, the system sees it and WhichAmiga reports it correctly but when I install P96 and attempt to run the CVision3D monitor file I get problems.

So once I click on the icon it immediately goes into slow down, if I try to move the mouse it stutters around for a couple of seconds until it completely freezes and the system will not respond. The only option is to reset the computer. If I not attempt to run the graphics card driver the rest of the system works normally. None of this is affecting the scan doubler module that is working fine.

I'm not sure if this could be power related (sorry I do not have any pictures of the A4000 PSU ratings at hand), any ideas on this one?

A4000, remove all hardware other than graphics card, start with basic workbench and install drivers. Does gfx card work now? If yes add other stuff one by one.
