why do my DMA settings shut down my computer?

Answer 1

Wow! DMA settings...been awhile since I worried about that. If you are using an older pc, that would certainly explain it. DMA settings are usually taken care of by modern day motherboards and software, but with older products you have to make sure that no other program shares the same DNA setting.
You can go into your device manager in Windows by right clicking on MY COMPUTER and choosing Properties, then click the hardware tab, then click DEVICE MANAGER....then click the VIEW tab and click the option to see the devices by RESOURCE....then you will see the DMA settings...... and see the list of devices you have with their respective DMA settings. View them to see which device shares the same DMA, if one does, you will have to change one of them so they dont conflict.
Good Luck!
