Comment 176 for bug 1671360

@Woody
I also have a Gigabyte Z68-ud3h-b3 in another computer (i5 2500k) and event though it's approaching 10 years old, and it's overclocked, it never did that (there were times when it would not cold boot, but at least the fans moved and you could reset the bios via clr_cmos, no problem). My brother has a Gigabyte z97 board and this never happened to him. I will try replacing the power supply since it is quite old, maybe it's related? I measured all the rails with a DMM though and they were in spec but there could be something a multimeter can't detect like noise on the lines or too much delay on startup signal. Thanks for the info anyway!

The board would not turn on at all, no fans ,no power supply start, nothing. And when it did start, it booted the normal bios no problem so it seems to me it wasn't bios corruption.

Anyway, it works OK now, hopefully it was just an isolated event.
While I was troubleshooting yesterday, I noticed on the back of the board there were very fine traces of silver colored residue. It looked like the board was soldered with solder paste and some of it spilled and flowed down on the PCB. I cleaned it as best as I could but I'm still worried about it. Any of you had this, or am I just being paranoid?
