emulatorII-list

When I switch the unit on the following occurs, 
(1) The boot in process display comes up and after sometime it will 
change to insert diskette and stay there. 
(2) The Harddrive starts to spin up and within a  seconds it stops 
spinning and then the harddrive LED starts to flinker(like random 
pulses)on and off and continues to flinker. 
(3)The 5.25 drive LED comes on and if you insert a floppy the drive 
will spin up but it will not read the disk (no drive head movement)
(4) some of the front panel LEDS comes on for a instance when switch 
on and then it remains off and no functions are possible
I have tried booting up with and without the floppy disc's but its 
still the same.
Can anyone help
thanks
