Leadtek K7NCR18g-Pro nForce2 crashing

I jsut put together a new system with a Leaktek K7NCR18G. I'm using 2 sticks of Kingston PC2700 CL2.5 (in dimm slots 2 & 3) and the itegrated GPU for now. Something is very wrong with my system. It POSTs just fine and boots to windows just fine, but it crashes hard when I try to play a game or watch an mpeg movie. Sometimes a small visual artifact will appear on my desktop for no apparent reason. I have 2 ideas as to what the cause could be. I've read that nForce2 boards don't like certain memory. This would explain the instability. The thing I thougt of involves the speed of the AGP. When the the system POSTs it states that my AGP port is running at 100 mhz. I was under the impression that the AGP ran at 2x PCI or 66 mhz. This would also explain the instability. If I go into the BIOS I can change the speed of the AGP to 66 mhz. The thing is, when it reboots it still reports the AGP running at 100 mhz. I've even tried running an overclock utility and clocking the APG down to 66 mhz. Does this make any difference at all since I'm using the integrated GPU? Any thoghts? My system is not overclocked in any way (besides AGP?), and the core temp is a cool 30C so those arent issues.
 
try with only one sitck of DDR memory. Test each stick on its own. Also check to see if they are any BIOS updates for your MB.
 
It was late last night when I was messing with this (and getting insanely pissed) so I havent exhausted all possibilites. I actually did try each stick of memory separately and the system crashed even faster. I'll install a BIOs update and try my old GeForce 2 card in it tonight. Does anyone have any thoughts about the AGP port though? Should it be running at 100 mhz? This was the default setting so it seems strange if it's wrong.
 
I have the same board (without the onboard video) and I've been dealing with crashing problems in certain games (although some games run just fine) too. My video card is a ATI (built by ATI) Radeon 8500 (retail non-LE - BIOS set at 66mhz if I remember correctly - I'll check) and the memory is 2x256mb sticks of PNY PC2700 (CL2.5 - Samsung chips) placed in slots 1 & 3 (as recommended in an article on amdmb.com). When the system began crashing (hard lock - had to use reset button) the first thing I did was remove the PCI modem card (it was the only card installed besides the video card) - no difference, so I reinstalled it and used an updated driver. The next place I looked was the sound system. I disabled the onboard sound through the BIOS and installed the Philips sound card I was using on my old motherboard. Things got better, but I still had random crashes. Then I looked at IRQ conflicts and sure enough the motherboard had assigned the video card and the sound card to the same IRQ (5). So I moved the sound card down one slot (away from the video card) and things got better - no crashes but still a random temporary freeze or some visual artifacts like you described. Next, I downloaded and installed the latest driver for the sound card, but that made things worse. Reinstalled the original sound driver and things are better again - not perfect but better. So by process of elimination I've come down to what may be a major culprit - Windows Me. WinMe worked just fine for me on my old system (Iwill KK266), but it may not be the best choice for my new one. So I've purchased a copy of Windows XP Pro. I'm planning to install that this coming weekend and I'll let you know what happens. Hope some of that helps. If anyone has any other suggestions please let me know.
