So, yesterday AM one of my PC's had video corruption and was locked up. Restarted PC and later in day it wouldn't resume from sleep. Restarted again, showed bios for a moment and from there on out it was essentially dead, no video.
I did a bunch of troubleshooting, swapping everything out and all the parts test fine, except the motherboard. I reset the cmos and still got nothing, in fact I couldn't get any screens to display at all until I put in an old PCI video card and then I got video. Strange. Mind you, this is just the motherboard (removed from the case) with minimal RAM and a powersupply (a basic bench config).
I put both a PCI video and PCIe video in the system and get no video on the PCIe slot, but the machine posts with both inserted. Of course I put in a few alternative PCIe video cards and none work. All the PCIe cards I tried work fine in other machines. Thus, to me it seems like something fried on the board and that slot is semi-dead. It's not completely dead, the fan on the video card will spin when plugged into that slot, but, no PCIe 16 cards will output anything to a display.
Before I go and replace the board (MSI K8N Neo4) though, I was just curious if anyone has any other ideas as to what it might be and possibly how to fix (maybe a capacitor--but they all look ok, is there a good way to test them?). I did check the northbridge fan/heatsink and it seems OK.
It sucks since s939 boards are hard to find now and still fairly pricey (low supply / medium demand I guess). All the other components work fine, so looks like I gotta spend some $$$ and fix or upgrade. Ah well, thanks in advance.
