I already had been operating with 64 megs in slot one, and 128 mgs ram in slot2
When I installed 256 SD Ram stick computer would not boot up. so I removed 64 mgs and 128 mgs sticks and installed 256 mgs stick and computer booted up. I then installed 128 megs stick in slot two with 256 megs stick already in slot one. Fired up but machine would not boot up, so I turned off computer, removed 128 megs from slot #2, fired up again and machine would not boot up. I removed 256 stick and tried to boot up with original 64 megs of ram, but it would not boot up. I had installed also flppy drive at the time, so I removed the floppy drive including floppy power strip from mother board and tried to boot up with 256 megs of ram. No luck and that's where it stands now with 256 megs of ram stick in slot one, but machine will not boot up. I even tried different slots but to no avail. Please advise.
