I have just bought a new Mobo ( well it was off ebay ) and when I plugged it up it up to the rest of my hardware............it turned on, all the fans ran, CD-drive+floppy made noise but nothing came on the screen. I have tested the Monitor, RAM (in both the DIMM slots ), PSU, the CPU is brand new and they are all compatable. I have tried clearing the CMOS with the jumper and the battery. I have tried using a AGP and PCI grahpics card as well as the onboard VGA output. Now I have ran out of ideas to please (((((HELP me))))))
The Mobo is a Foxconn 760GXK8MC by the way.

Following the thread from , and , here are focused, practical checks that often find the fault when a used Foxconn 760GXK8MC powers but shows no video. These avoid repeating the obvious tests already tried and concentrate on things people miss or can test without specialist tools.

Try a true “breadboard” boot: move the board out of the case onto a non-conductive surface, fit only the CPU (with cooler), one known-good DIMM in the primary slot, the 24‑pin ATX and the 4‑pin/8‑pin CPU power connected, and a video card only if needed. Fit a simple chassis speaker to the front-panel header (many boards won’t signal without one). Short the power-switch pins or use the case switch and watch for POST beeps or POST-card codes. This isolates case shorts, standoffs and front-panel wiring as causes.

Check BIOS/CPU interaction and the BIOS chip itself. Used boards may ship with old firmware that doesn’t recognize a newer CPU. Look up the Foxconn CPU-support list and BIOS revisions for that model; if the BIOS chip is socketed it can be reprogrammed or swapped. If the CPU/socket has bent pins, or the socket retention/contacts are damaged, the board will also fail to POST even with otherwise-good parts.

Do a careful visual inspection for damaged or bulging capacitors, burnt or cracked components around the VRM and chipset, cold solder joints, or corrosion. If any physical damage appears or the BIOS cannot be recovered, component-level repair is usually uneconomical — replacement or refund from the seller is the practical route. Always work ESD-safe and document photos when dealing with an eBay return or dispute.

Will it post with only one stick of ram and no disk drives pluged in. Try with onboard video first then cards. does it beep at all?

I am only using one stick of RAM and no it doesn't. I had already tried that.

If everything you mention is good, I would say you've narrowed it down to a bad board.
I once bought a new psu that was bad,a slim possibility. If moniter,cables are good,I don't see what else it could be. Was it a used board?

Member Avatar for :)boysie

Yes it was used. I think it is a bad board but I would like to know what on it is bad and how do I fix it?

Member Avatar for :)boysie

Yep it is a bad board

Member Avatar for belikemike

I have no idea how to fix a bad board.
I'd just get another one.

I preseume you already resolved this. However, if not: make sure you put the memory stick in DIMM Slot 1. That board gets pickey if you put the memory in Slot 2 instead.

Hope that Helps!
