Once I got things running (win7RC) all was well until I started to hear a high pitched buzz. I tried to see where it came from but it's hard to determine if it's the mother board or the PSU as many suggest.
Through testing I've managed to make it go away, what I did was turn off/modify various settings in the bios. Then I proceeded to turning them back on such as power settings and CPU settings.
The last thing that I didn't restore was the CPU auto voltage, when it was on auto the setting was at 1.2555V but I switched it to 1.2000 and I think that's what made the buzzing noise stop.
Now my question is what's the best way to resolve this?
Get a better power supply or is it the mother board? (do more testing?) Return the mobo?
Misc: The buzzing is when the computer boots windows and it usually stays while using the OS. It doesn't do it while in a bios screen.
When I was using my amd 932 it never happened and the i7 is at stock speed as well.
I have the same fan noise in my HP Pavillion. The best I can determine is the cpu fan. HP wants me to send it to 3rd party repair service and "refurbish" it, which means they want to take it back to factory settings. I just want to find the heat sink fan and replace it myself. Trouble is, I can't find one . The board is a Pegatron M2NL789-A. Any advice would be appreciated.
