I recently installed an additional hard drive and all worked well, I upgraded the memory to 96mb and attempted to install a cd writer. I could not install this unit, but I had unplugged the ribbon cables to the 2 hard drives and the existing cd rom. I replugged and rechecked the connections numerous times and they are correct. I cannot access windows on start up. I can get into the set up, but that is all I can access. I tried a boot floppy but no help. All I get on start up after the bios information, is a blank screen with a blinking cursor which cannot be accessed. The hard drive continues to run but is not recognizing anything. Help!!
