Re: ASUS ASUS P5VDC-MX Dead CPU?
Small ceramic caps that were part of the motherboard's design but were never installed by the manufacturer to save on costs. You can see many empty spots all over the board for those. And also for some 'lytics too. No telling if/when this corner-cutting can backfire.
Also, just because they are not bulging or leaking doesn't mean that they are not bad... but given that they are Panasonic, we could be a lot more confident that they are probably okay.
Yup, it is.
So like I mentioned in my previous post, that means either something is wrong with that 7805 regulator on your P5VDC-MX or perhaps something downstream is shorted to a higher voltage rail, thus bringing the output high. Or just not enough caps on input/output of that 7805.
Nope, not from my multimeter.
I can only think of two things to cause this: mains wiring fault (lack of ground likely) or static discharge from your body.
Make sure you touch something that is metal and grounded before working on your electronics. That should minimize static discharges. Also, check the ground at the plug where you had this incident happen. Shouldn't have too much of a potential difference (well, preferably none) from neutral - like a few volts at most.
Yes. If you can see a spark, many times you will be able to hear it too.
I am *guessing* from the area around the CPU (you didn't specify). In that case, do NOT run the board like that AT ALL. You could easily blow a VRM driver.
