HP/Pegatron/ASUS M2N78-LA (Viola) mobo replacement

Postby ddebevec » Wed May 16, 2012 1:14 pm


I am hoping to gather some information for a replacement mobo for one of the ill-faded HP Pavilion Elite m9350f Desktop PCs. This is the model that sported the Pegatron/ASUS M2N78-LA (Viola) mobo which had problems with the chipset getting too hot and causing all sorts of intermittent problems. My wife bought one a few years back and it work up to a couple of months ago. Now I have it and I would like to know if anyone could suggest a comparable mobo that could be substituted for the failing component. Below are listed the specifications of the existing mobo:
