System Lockup Nightmare

Hey everyone. I've got an issue right now though that has me ready to put a bullet through my computer and buy all new components... First off, here's my system specs:

Athlon X2 3800+
DFI LanParty UT Ultra-D with the latest official BIOS
Thermalright XP-90 HS with 92mm Panaflow fan
2gb Corsair XMS (Twinx2048-C2PT)
128mb BFG 6600GT OCX
3x Seagate 7200.10 250gb SATA2 drives
1x Seagate 7200.8 250gb SATA drive
NEC 3540A DVD burner
Samsung 16x DVD ROM
PC Power and Cooling 610watt PSU
Antec P180 case

This system has given me a tremendous amount of grief with instability for the last month or so. It started out with an Abit AN8-SLI board that would lock up frequently but not with any degree of consistancy (though it was very common when plugging in USB thumb drives). I tried quite a few things and ended up replacing the motherboard and doing a clean install of XP. Now here's the situation. Totally at random, my computer locks up. The screen freezes, the sound will get stuck in an endless loop, and I'll have to reboot. I tried my ATI x800GTO2 in the machine and with that in there, instead of lockups, I get a Stop 0x0000009C error, which is supposed to be a hardware issue of some sort according to Microsoft's knowledge base. I tried a new power supply (the PC Power and Cooling - previously it was an Enermax 550watt unit). I still get the same problems. I checked CPU temps and they're running in the 40s. I checked GPU temps and they also are within tolerance - around 60 under load, 50 otherwise. I tried relaxing timings on my RAM to 2T instead of 1T. Same problem. I've tried running the RAM at 8,3,3,3 as per SPD settings and had the same problem. I've tried boosting the voltage as high as 2.9v on the RAM but it doesn't help. The CPU for some reason seems to default to 1.3v instead of 1.35 like most 3800's so I tried bumping that voltage up to 1.35 and still get the lockups. The CPU is running at stock by the way. I've tried taking it down to 2 hard drives to no avail. I've tried changing all the drive cabling (SATA and PATA) and still get the lockups. I've removed all USB devices except for my mouse. Still locking up. I've done a clean install of Windows and get the same results. The machine passes 24 rounds of memtest (the one built into the BIOS). I've tried running hours and hours of Prime 95 on each core (6 hours if memory serves me correctly) and it passes. I've tried installs with and without the Nvidia storage drivers and that doesn't make a lick of difference. I'm currently running Seagate's diagnostics on all the hard drives in the system and we'll see what that turns up but does anyone have any suggestions? I'm totally at my wits end here. I'm tempted to put a bullet through this system and buy a new one at this rate but finances do not permit such luxury. Any advice on what might be causing this issue would be greatly appreciated! Sorry for the long first post by the way.

Sounds like bad RAM, even though it passed memtest. Have you tried running with only one stick?

Yes, I have the solution for you!! I had the exact same problem!!

There is a known issue with the Abit AN8 SLI and the new BIOS when using an X2, it is related to the USB as you noticed. Mine also locked up randomly overnight, etc.

Downgrade from whatever version of the BIOS that you are using to version 15. I was in your shoes EXACTLY and this fixed my problem. From what I read, this is the newest version of the BIOS that works properly. Other boards have had this problem and resolved it, but ABIT never did.

Also, you can disable the second core, but that would totally suck!

Let me know after you fix it if you can get CnQ to work. On this BIOS version, I can't :(. And I really really really want it to work too :(.

I missed that you had the problem on the DFI board too, it might be the same type of issue. As I read, it happened on other boards too.

Anyhow, try the Abit board with the older BIOS.

Otherwise, do some intensive googling.

The system finally crapped out on me such that it was unbootable and wouldn't post. I gave up and bought all new parts and have been selling the parts from the old one piece-meal with a warranty because I'm so sick of t-shooting this. I had an older BIOS on the AN8-SLI and had similar issues so I don't know if it's the same problem you had run into or not with that board. My buddy bought it from me and is RMAing it. I switched to a Core 2 Duo (and an entirely different set of problemos)...
