[comp.sys.atari.st.tech] SICK 1040

jharres@sleepy.bmd.trw.com (10/17/90)

My 1040 recently developed an ailment.  It boots just fine but after several
minutes it locks up.  Hitting reset changes resolution from med to low and
garbages the display.  The data appears to be the original prior to the reset
but in low res.  A power cycle (30 sec wait) results in a white screen.  After
sitting for 10 to 15 minutes it will reboot leading me to believe it is a 
heat related problem.  This was confirmed the next night when I broke out 
the blow drier and aimed it thru the louvers.  In a minute or so it reboots
and runs for hours.  This worked for several evenings without new problems
until last night when I popped in a different disk and hit esc.  Now I had
a disk directory with duplicate (completely identical) file names and other 
file names missing.  Several esc's didn't change the display.  After inseting
several other disks that displayed correctly, the problem disk showed the 
correct contents.  

Any suggestion as to what part(s) to suspect?
