with bootup u mean what? power on the machine or booting a hdd / floppy ?
remeber ntsc/pal and other monitor drivers should be sorted out for your system.
which monitor do u use?
if its not a wb boot then my guess is...reseat the 3.1 rom's in it... take em out and put em back in...or just PRESS em firmly onto the sockets again..
hope it helps...
more info would be appriciated.
