Try this:

boot to safe mode, hold the control key down while booting, select command prompt only from the Start Up Menu. At the c:\ prompt type in this:

REGEDIT C:\DMA.REG HKEY_LOCAL_MACHINE\ENUM\ESDI

this will export a registry file called dma.reg to your c:\ root that will contain the DMA info for you Harddrives.

Then, type this:

Edit c:\dma.reg

change all of these lines:

"DMACurrentlyUsed"=hex:01

to this

"DMACurrentlyUsed"=hex:00

save the file (as nodma.reg - hit "alt" key on keyboard to get back to the file menu) and import it to the registry by typing this:

regedit c:\nodma.reg

Start windows by typing win and then hit enter on your keyboard...

Lemme know if there is any change on boot up.

check the file C:\windows\system.dat and make sure that it isn't set for read-only

You may also benefit by doing a normal shutdown, leaving system off 2-3 minutes.

Reboot holding CTRL - select MS DOS Prompt only, navigate to the windows\command prompt (subdirectory) and type
scanreg/fix.

Scanning and fixing registry errors sometimes helps.

Is WindowsUpdate current?  Very important, many problems have been patched/fixed since original release.

Norton utilities 2000 and DirectX problems may also play a role here, if pertinent to your setup.

Is this a new install or an upgrade.  If upgrade, what was the prior OS and version/environment?  What all is running from autoexec.bat, config.sys, win.ini (load= and run=) and what is called from the start up files?  All can be checked from
start-run->msconfig

Any other errors reported in the setup process?

Is BIOS current with needed updates from BIOS manufacturer?  Is PNP OS in BIOS setup as yes?  Is Virus check in BIOS disabled, as well as Power Management, so Windows can control it?

I DO suggest you follow Astaec's advice and look for a BIOS upgrade at your motherboards manufacturer's website, and , while you are there look for other updates such as ide drivers, agp drivers, etc,etc,etc..., also, you can try to re-enable the dma on the drives that support it from within windows again, open device manager, expand the Disk Drives component of the tree, double-click the drive you want to set to DMA, click the settings tab, check the DMA box, do the same for all drives THAT SUPPORT dma. You may want to go to the drive manufacturer website and locate the documentation for your model of drive and see if it does support DMA, it should if it is less than say, what 2 years old...?  

Cheers.
