I didn't realize you were using that RAM card. There's the problem then. 
The AE GS RAM card isn't compatible with the ROM 3. If you check in the 
RAM Disk control panel you'll find it shows the wrong amount of RAM. 
In the RAM Disk control panel if you add up the RAM Disk(if you're using 
one), RAM in use and the free RAM then a ROM 3 with no RAM card will a
total 
of 1151K free without a RAM card. With a 1.5mb RAM card your total RAM
should 
be 2687 but with the AE GS RAM it shows a total of 3199K. 512K more than you
have. The card will work right up until a time when your IIgs tries to
access 
that non existent RAM. 
There were some AE cards that would work in a ROM 1 or 3 and there were
some 
that you had to change PALs. Unfortunately they never made ROM 3 PALs
for your 
card.
