I've recently upgraded my HTPC around this new mobo. Once the system is running its performance is flawless with BD playback. However, there are a couple of quirks that I haven't iron out nor really understand, hence this post...
1) It seems the system goes thru about 2-3 POSTS before the WinXP logo finally appears. I don't know if this is a 'warm-up' issue, or something else. As I said, once Windows does load it works fine - for watching hi-def discs, surfing, or game play.
2) This next issue is the most annoying. My system is connected to my HD display via the DVI port of my GeForce 9600GT video card. I am not using the onboard graphics. My HD display is also connected to other devices, the primary source being my SA8300HD DVR via the HDMI. Here's the problem. Whenever I change the source input on my TV - via either the remote or TV buttons - or cycle thru the other inputs the HTPC powers up and starts to boot! So, if I power down the HTPC (DVI-1), and then change the TV input back to HDMI (for DVR use) the HTPC immediately restarts. The system is somehow sensing the signal on the DVI port of the video card. I've checked the BIOS settings and the only option I can see that may affect this - the 'PME Event Wake Up' is DISABLED. Could it be a setting on the 9600GT? Has anyone else experienced this. Known problem, or my HTPC unique?
