My A4000T is out to lunch

Over the weekend, my A4000T (Power Tower MK-II) started acting strangely.  It was running fine, then programs started locking up and when I typed in a CLI window, the characters were showing up all goofed up or not at all.  Now it refuses to boot.  What does a flashing yellow screen mean???

Sounds like I'm going to have a lot of fun looking for problems this weekend.  Thanks for all the suggestions!  I'll update when I find a solution.

Well, my A4000T is back up and running again.  Over the weekend, I had some time to tinker with it.  I had to replace my CS MK-III 060/50 accelerator card.  Good thing I had a spare!  The old one appears to be having some sort of heat problem.  It works fine for up to about 30 minutes, then starts going haywire.  Swapped the RAM off of the old card onto my spare, and everything works fine again.

Now I just need to find a place to get the broken one fixed???

Anyone have a suggestion as to where I can get my broken CS MK-III 060/50 card fixed???
