Choppy Sound or Video?

Has your video and sound become choppy? This could be because your IDE Primary and Secondary Channels have reverted back to PIO Mode instead of DMA Mode.

To see if this is your problem go to the device manager (right click "My Computer>Hardware>Device Manager) and expand the IDE selection. Right click the Primary and Secondary Drives and in the next box choose Advanced and look to see what mode it is in. (PIO or DMA) If it has reverted to PIO Mode then go to the following site and download the "reset DMA" script. Run it and if this was your problem it will be fixed when the computer reboots.

Be warned that this could happen again. XP will revert back to DMA mode automatically after 6 CRC errors which could be caused by unreadable disks or files.
