There is a thread here about guys with random BSOD auto reboots while in Windows (not the double post issue (fixed by setting spread spectrum to enabled) or the RAM not being set properly prob that causes
freezes (fixed by setting XMP mode or configuring all RAM parameters manually) that solved things with a DIFFERENT BRAND PSU. They figured it out because it would happen if they moved (jostled) the PC, and they would have to replug in the PSU and some devices to bring it back. Which means the connector contacts either to the PSU itself or to the mobo were not making sufficient strong electrical contact with mating male pins in mobo sockets. The 2 PSU involved were Corsair and Antec
Just fwiw - but one person with no sound on another forum tried a dif PSU and it didnt help
Also as far as CPU, the
replaced Southbridge has the
INTEL HD audio channel, which is the one you get in dev manager when you install Win 7. I dont recall, did anyone have this prob with the B2 SB?
