I recently purchased a barebones system from Tiger Direct and everything worked fine until I returned from vacation and restarted PC that had been shut down for the week I was gone. When I started PC, it is now hanging up and displaying a "Post Code 50". I have been tring to find out what this is. I can not get into SETUP or the Boot Menu. The PC will not even get to the point where I can try to start from a floppy. The system just locks right after it displays the BIOS info, the motherboard info - 7NJL6 08/04/2004, and then - Main Processor : AMD Athlon XP 1733MHz. Then the "Post Code 50" message. Any ideas? I think the motherboard - ChainTeck 7NJL6 went south on me. I have a AMD XP 3000 processor, 512MB Ultra DDR ram, XGI 8X AGP video card and a 425W power supply.
