I have a problem. I have a Packard Bell S621, 233MZ pentium, Tried to upgrade video card with voodoo3 2000 pci card. Installed card and seemed to be working OK. Changed drivers to new board. Forgot to disable old board (is part of motherboard). Have viewsonic afi 17" monitor which worked fine. Next time I went to boot up, hard drive started, it accessed cd-rom ( did not access the floppy drive ) which is not part of normal startup. Screen is blank, monitor goes to sleep. Windows 98 does not start. Hard drive activity stops. How do you boot up into safe mode? And any other info can be helpful...
