A7N8X Deluxe and nvmcp.sys

[Knightcomm]

I decided to get back into gaming recently and tried out Final Fantasy XI. I have been playing for about a month, and now my computer likes to reset about every 10 minutes. Usually when these errors happen, I get the lovely blue screen and it gives me a LESS_THAN_OR_EQUAL_TO error with the nvmcp.sys. Other times the video will get all funky (rendering seems to go to hell) and I alt-tab out and everything is fine. I feel that it is my video card (Asus V8420 Ti4200 128MB), so I ordered a Radeon 9800 Pro to replace it. Upon further research, I find that it could also be my BIOS version (some say version 1004 is better than 1007) or my PSU (400W Raidmax). I have no other card plugged into the mobo other than video, so power should not be an issue. I even tried taking my storage HDD and disconnects my ROM drives to test this out, but the problem persists. I have tried other drivers, as well as different video BIOS versions. I am not sure as to how, changing no settings in my puter, this problem could start unless it is a hardware issue... but with MS Windows running in the background, you never know. System specs for minimal hardware test are:
CPU: XP2400@2250MHZ(180MHz FSB) - Used to run stable @ 2400MHz
Mobo: Asus A7N8X Deluxe ver. 1.xx
RAM: 2x512MB Geil Ultra PC3200
Video: Asus V8420 GF4 Ti4200 128MB
HDD(s): 2xWD360 10,000RPM Raptors
PSU: 400W Raidmax
HSF: SLK-800U w/ TT Smartfan @ 36C

Let me know if require any other information.

This may not be the problem but maybe its the southbridge heatin up? I used to get staticy sound after playing some of my games for a long time and when I finally felt my south bridge it was painfully hot. So I slapped on a south bridge cooler and I havent heard even a single crackle. I know that has nothing to do with your problems but I thought Id let you know. Its also possible that it could be your CPU being unstable but good luck to ya.

Actually, I am retarded; you have a good point. The MCP-T is run through the southbridge, and all three of my nForce mobos have this same problem with the crackling sound. I will try to find a quick fix to this till I can get a Zalman cooler on there.

I've gotten my fair share of those I think "IRQ_LESS_THAN_OR_EQUAL_TO" Error messages. I'd like to know what's causing them too. Check out www.nforcershq.com for help w/ any nForce mobos.

I got these messages with the kmixer.sys using the 3.03 drivers
Reverted back to 2.45 and no more BSOD
DO NOT USE NFORCE 3.03
