Hi all,
I just thought that I would share some knowledge.
A while back I purchased a MSI A6000 from firstin.co.nz, it kept stalling for 10-90 seconds at a time, with no error reports or event logs.
After trying a reinstall of windows - same issue.
After much searching on the net I finally found a solution!
The ATA controller driver from nvidia is the culprit. Rolling back the driver to the generic microsoft version worked.
Thanks pigmoose from http://archive.slickdeals.net/showthread.php?t=1680584&page=25
Hope this helps anyone who also purchased a MSI.
