I would say the issues you are encountering are either software, heat or voltage. MBM does not monitor the 3.3v right for our boards. Monitor your +5v in bios or through software keeping your rails perfect make a big deal on these boards especially when overclocking. Second what nforce drivers are you using and did you hack them so it wouldnt install the display driver built into the UDP package. You should also NEVER install the SW IDE driver its EXPERAMENTAL to say the least. I would follow this procedure for the software installation. Also if you have a santa cruz you should disable the game port for it...there are issues with nf2 and the santa cruz game port.
<<<<<<<<If, like most enthusiasts.. you intend to tinker with various nforce drivers please remember that..as with previous UDP/Nforce drivers.. you MUST let Windows detect bits and reboot between uninstalling any older drivers and then installing newer ones. Not doing so will cause problems. It should go like this:
1. Uninstall all nForce bits.
2. Reboot.
3. Let Windows try to find, and fail, at all the nForce stuff.
4. Reboot.
5. Install the new nForce drivers.
6. Reboot.
7. Install the graphics drivers all by themselves.
8. Reboot.
If you still can't get your graphics to install, it is probably the issue that was in the previous install packs. It means re-install the whole OS.>>>>>>>>

<<<So I read around a little at nforceshq and guys are hacking the nforces with newer audio drivers ect. So I figured I would do the same thing except take the drivers that cause instablity and the drivers I dont use out of the install.
This is so damn easy.
1. Download winrar

2. Download the Latest nforce driver 3.13
http://www.nvidia.com/object/nforce_udp_winxp_3.13
3. Right click the nforce.exe file you downloaded and extract it to a folder.
4. After extracting it to a folder open the folder and Delete the folders that you will not need or do not want installed. I myself on my plain jane 8rda removed the AudioDrv, AudioUtl, Display, Ethernet. After I deleted the folders I didnt want then all you do is run the setup.exe icon in the folder and kaboom...no more drivers you dont need or drivers that cause issues.
If you have a full feature nforce 2 board with soundstream and onboard ethernet you will want to remove only the Graphics driver folding in the packages UDP.
Remember dont install that SW IDE driver. I installed it with some nforce UDP releases and it worked ok...I've installed it with others and got big problems. >>>

Hope this helps out some...I had some problems for awhile also with driver issues.
Edit to add: You should download "Driver Cleaner 2.6" and make sure you dont have any left over nvidia dets on your system.
