Working on an old P100 system. System was fine until installing an ATA modem card and doing some other "upgrades". Now at power on there is nothing on the computer screen -- just blank -- not even a flashing cursor. Tried switching out memory with no results. With no memory installed there is a LONG beep followed by several shorter beeps, then nothing. Maybe it is not worth pursuing, but we are rather poor here in Romania and are still using some 486 machines. Any help you can provide will be much appreciated.

when the memory is isntalled does it sound like it's booting normally? do the fans spin up? the HD? is there any beep?(should be one) do you have access to another monitor? do you have access to another video card?

The power supply fan is working. The monitor is working fine on another computer. There is no fan on the CPU -- only a heatsink. The HD spins up. The 3-1/2" floppy does nothing and will not boot. There is NO beep when memory is installed.

Thank you for your reply.
