when i installed it it asked me to insert a floppy and when i rebooted it asked me whether to upgrade the bios, i said yes.
at end of the process suddenly all gone, no screen display, no power light, but i can hear the fan sound, i am unable to shutdown the pc for that i need to manually remove off the power supply from wall.
