Ok, Ill try to keep this short. Elpina motherboard. turns out to be PC Chips M577 , also known as Amptron PM9900. Moved perfectly working motherboard, hard drive, cards etc from one AT case to another. Tidied up all the cables etc..powered up..fans spin, hard drive spins no video. OK, trust me here, I went thru the whole routine, changed vid card, changed cpu, changed ram, changed deoderant, changed back to old working power supply etc etc. Totally disconnected everything from board except for RAM, cpu, vid card, took mobo out of case to make sure it wasnt shorting out. Still no video.

I didnt have a manual (I found it now though) so I wasnt sure of the connections for the case connectors..ie..reset, hdd led, turbo etc. Probably didnt have speaker plugged up correctly since I never heard any beep codes at all. I believe I did have the reset switch hooked up correctly.

So basically now I want to know this..do I HAVE to have the keylock or turbo switches hooked up to boot. I do remember the old case had turbo light lit when running. If keylock isnt hooked up will it think its locked?? What about "sus sw"..if that is for suspend, what will happen if its not hooked up?

Any suggestions of any sort will be appreciated.

Link to manual, page 9 shows connections Im speaking of http://www.amptron.com/manuals/PM-9900/m577v30w.pdf

Thanks, JP
