Help Me!! Intel Mobo D845PEBT2 system problem

Loaded Win2000 followed by SP3 with no problem. Then I tried to load the latest chipset drivers and the system latched (or froze)! I tried all of the different methods Intel published to get it to accept the chipset drivers with the same result. I even RMA’d the mobo and processor with no change. Finally after about 6 clean installs of Win2000 SP3 I managed to get the drivers in without a latch-up. Probably just the chance of trying it enough times. The device manager showed all drivers installed correctly so I thought my problems were behind me. Nope.
A few days later I got an error in the Event Manager indicating ntfs file system corruption. Chkdsk runs on the next boot up and finds numerous problems and fixes them except for once where I lost some data. This ntfs corruption has been happening every few days since I completed the system. Here’s what I’ve tried:

Memory: I have run SimmTester's "DocMemory" RAM Diagnostic software for over 100 hours with no problems found.
Power and heat: I’ve kept an eye on these using Intel’s Active Monitor software and all looks good.
Burn in: I even ran 3Dmark2001 SE for 11 hours continuously and no problem occurred.

Please.. Does anyone have any suggestions as to how I might debug the ntfs file corruption problem??
