Hey all, I just bought essentially a system without a case. It consists of a J-Mark J-656VXD motherboard with 96mb of ram and a Cyrix 6x86 processor. The system SEEMED to work before it was shipped, according to the buyer and his photos. It worked when I first started using it as well. What it would do is turn on and go through the bios screen, ram count, etc. sometimes but other times it would just give me a black screen. After this went on for a bit, it just stopped outputting video completely even with two different video cards. The jumper settings appear to be correct, I've taken out ram and tried all kinds of combinations to check that, I've tried to reset the CMOS, looked for broken solder joints, reseated the CPU, and various other things. I'm AM using an ATX to AT power supply adapter, I don't think that would have much to do with it, although I could be wrong somehow. I've tried rigging up a pc speaker by soldering one of those round ones to a connector, but I don't really know which pins would go on which wire so I haven't had any success with that.
I'm just kind of at a loss save for the CPU or motherboard going bad and unfortunately, I don't have any other socket 7 CPU's to test with it.
Do any of you guys have any ideas regarding what I should do? Do you think I could maybe get this to work? I have one of those diagnostics cards coming tomorrow, the kind that Adrian's Digital Basement uses, so hopefully that sheds some light on the situation. It's just disappointing because I've just been in a really tight spot lately and can't really afford a whole new board which may not even end up working if the problem is the CPU or something.
Any help would be GREATLY appreciated. Thanks and God bless! You guys have been really helpful to me.
