Finished assembling my new computer setup last night, but I'm having some issues. Here are the specs:

Athlon 64 3200 winchester (engineering sample that someone gave me, but it works fine)
A8V deluxe rev 2.0
1GB Corsair VS (2x 512mb 2.5-3-3-8)
XP90 with panaflo FBA09A12H-1A
BFG 6800 GT
Maxtor 6Y200P0 (200gb IDE disk from old computer)
OCZ modstream 520W

The system was locking up insistently in windows but a bios upgrade fixed that. The problem now is that it keeps locking up in games after several minutes of play, sometimes with a BSOD and sometimes just a freeze. Setting the AGP to 4x helps a bit but the problem is still there (newer games rarely last over 15 minutes). It's fine in windows and has no problems with prime95 or other CPU-heavy programs. I have seen many complaints about the VIA AGP driver doing this same thing but they all only occured with ATI cards so I don't know why I am getting the problem. There seems to be a workaround to fix this but it requires a driver file from SP2 that I can't find anywhere as a standalone download and I don't want to move to SP2 just for that. The video card and memory were taken out of an older setup and worked fine there (apart from this, which I haven't run into on here yet).

The voltages all look good except for the vcore, which is undervolting by 0.05V according to asus probe, so I bumped it up to compensate. The processor temperature is slightly higher than what I would expect but that is probably due to the preproduction cpu that is apparently rated to run slightly warmer than current ones anyway.

Also, Logitech's MX510 background service (em_exec) seems to crash windows quite often if it's running, although I don't know whether that's because of the motherboard or the driver. I can't use some of the mouse features without that thing though.

I got this motherboard over the MSI K8N Neo2 because of all the problems I have heard about the latter and I have had a good experience with previous Asus boards. There are still 10 days on Newegg's return period though and I don't have much more time to spend struggling with this, so is there something simple that I'm missing or should I just return it and try the MSI one?

By the way, the XP-90 had a significantly large scratch on the bottom out of the box. The scratch is to the side of the contact plate though and that part doesn't touch the processor, at least the way I've oriented it, so it's probably not worth the trouble of getting it replaced, right? (got it from Coolerguys)

If you dont like the Asus board, try the ABit board... I hear it's quite good also. I have the A8V without any glitches..so far

Well the problem seems to be with the VIA driver. I believe the Abit board also uses the K8T800 pro.

Looks like I'm getting somewhere. I had tried setting AGP to 4x and disabling fast writes individually and it didn't do much, but doing both of these things at the same time has removed the game-specific crashes. However, the general (windows or game) crashes are actually still around, although they are less frequent than before., occurring every few hours without any demanding programs.

Has anyone used the 1010.003 beta bios for this board? Wondering if I should try that out.

Looks like dropping the LDT to 4 fixed everything. This board seems to overclock the HTT bus by 0.3mhz by default, which could cause issues if the via chipset is very sensitive to hypertransport speeds over 1000mhz.

Now I just need to find out why AGP 8x is slightly slower than 4x in 3dmark05...
