Help!
I'm not sure watch to do with my ST. Anyone have any suggestions?
(Before you start, let me list some symptoms.)
VERY erratic behavior. Sometimes, it works perfectly, others it refuses to
boot.
When it does boot, sometimes it will refuse to recognise that my disks are NOT
blank! Other times, it will just continuously reboot by itself over and over.
Sometimes, the screen literally goes crazy and the ST crashes (or small blobs
will appear on the screen and then the works)
Sometimes a program which works fine (such as Uniterm) will end execution and
return to the desktop at random (sometimes right after it loads!)
Just to put things in perspective, this has been happening since I've gotten
the computer (and I was zealous, from what I can make out on the motherboard is
dated 1985 rev. A) and has been "repaired" quite a few times.
                                Any suggestions?

USENET is.)
