I've got a little home-automationy project I've been tinkering on, and a kind forum member gave me an old Asus A8V-VM socket 939 motherboard to use for the control system. Unfortunately the board is giving me some trouble (although it worked fine for the original owner), and I'm having difficulty tracking down the source of the issue. TBH, I'm a bit embarrassed to ask for help on this one (because I feel like it's probably something glaringly obvious that I'm somehow not seeing), but F me, I'm stumped.
The problem seems to be centered around onboard video. The board POSTs just fine, and I can get things like Clonezilla and Memtest86 to boot and run without issue. But Windows installers (10, 8, 7...haven't tried XP though) crash/hang when starting the GUI, and while I can get both Ubuntu and Mint to run and install, they do so in "software rendering mode" only, thus dramatically limiting resolution and performance. Normally I would write this off as a defect with the onboard video, but here's the real head-scratcher: the problem persists even when using a discreet video card. This board uses the VIA Chrome9 IGP -- which I know was a pretty unpopular, short-lived component -- but I don't think this would have any effect on the use of a stand-alone video card...right?
Anyway, here's what I've done trying to track down the problem so far:
* Flashed the most recent BIOS
* Tested/swapped out every other component (except the CPU; I have no other 939 CPUs on hand)
* Pulled old CMOS battery, let board sit for a bit, put in new CMOS battery
* Used every combination of memory slots/modules imaginable
* Used both USB and PS/2 peripherals (I've heard rumors about some old mobos not liking USB peripherals)
* Tried other versions of the aforementioned OSs (older releases, 32-bit versions, etc.)
* Used 100% default BIOS settings
* Use every possible permutation of BIOS settings I can imagine, paying special attention to default video source (Integrated, Discreet, etc)
* Cursed creatively
Even though I'm (necessarily) doing this project on a shoestring budget, by this point I probably would have been better off just buying a new bargain-basement mobo instead of scrounging something from the Perpetual Freebies thread. But, you know, I already had the memory lying around, and a big-ass 939 cooler, and... Plus, I was really looking forward to OCing an Opteron once I got the system up and running. Sigh.
So, any thoughts before I take this thing to the recycler?

TL;DR: Asus A8V-VM. Onboard video no work, discreet video no work. What do?
