Just recently reinstalled after going from a tempory old 60gb hd to 2 laptop drives, connected as raid 0 on my Mb's built in hpt370.

format full xp(sp2 nlite) install, but had stuttering sound.

so, format full xp(sp2) install, stuttering sound.

format, xp(2600)+sp1, stuttering sound.

Now I used this board for years before it became the car Pc and never had this problem before.

So for anyone else who ever has it, the answer is the raid driver, even though you install one at the start of the windows install (or you cant see the drive etc) windows goes and changes it!

go into device mangler, scsi, raid controller, driver, make sure it say highpoint and not microsoft or the dma access will freeze the pci bus etc
