Make sure your video cable is good. Test it with a multimeter. Make sure
its plugged in properly. Check the video connector on the motherboard and
make sure it is still in tact. Over the years, the strain of putting in
and pulling out the connector tends to break the center conductor on the
video jack.
Assuming that's all good, pull out all the cards and then fire it up.
Does it work now? Ok, put in each card one at a time, starting with the
disk controller that was mostl likely in slot 6. Was there anything in
slot 7? Just curious. Usually there wasn't, but things that did go there
included special video cards and hard disk controllers. The fact that the
disk is spinning up is a good sign. Does it do its recalibration (sounds
like the disk is farting)?
Anyway, start putting in each card one at a time until you find the one
that's causing the problem. Maybe just the act of reseating the cards
will help.
If none of this works, uproot and reseat all the ICs. If THAT doesn't
work, did you first check to make sure the contrast or brightness controls
on the monitor were set appropriately? Always check the stupid things
first.
