Install Hangs

Does anyone know what might cause the install to hang and make the keyboard blink during an FTP install? I am installing SuSe 8.1 on a machine and I have tried several times to get it loaded but it fails and locks up never on the same package but always around 75%-80% of the total install. I have plenty of disk space on the machine I am installing to. I have ruled out network since I have another machine that installed fine, maybe a hardware issue? Thanks in Advanced... Sean
