Mbox 3 possible defective device??

[andrewbrg]

Hi All,

I have recently purchased an mbox 3.

I am using it to connect my electric guitar to my laptop.

My laptop specs are as follows:
Win 7 64bit
8gig ddr III
i7 @ 2.0ghz

The device seems to function correctly until I set the buffer to 128 on the 96000 sample rate.

After doing this and running the device into either Reaper DAW or Pro tools my system crashes after roughly 10 seconds or so.

A process called 'NT Kernel & System' runs up to 90/95% and just eats the CPU alive.

I have downloaded and installed the latest drivers from the avid site.

Does anyone know what might be causing this issue? could it be a defective mbox unit?

Thanks
