check your interlocks, modern machines are usually smart enough, but i've seen older machines hang in the boot process, before being awake enough to tell you whats wrong, with a sticking interlock switch

if you have a good backup, boot up erasing the memory and restore your good params, it could be a ram parity type issue... last resort hopefully

I have the same problem in my machin .SOHow to boot up erasing the memory and restore params

I have the same problem in my machine .SO How to boot up erasing the memory and restore params

search the forums but its an involved process... i wouldnt do a memory clear-boot without full backups of both programs/params as well as an F-ROM backup to a pcmcia flash card... but really i think the only things lost are your params/programs...

then you have to reload them... at least a couple manually to get rs232 connection going and then via computer, but if this isn't familiar to you i wouldnt recommend it... hire a professional, or visit local shops and try to find a savvy employee who may help you for far le$$
