Exploded motherboard resistor...Please help! :(

[Vyse Dyne]

I have an Asus K8V Deluxe motherboard, and I recently discovered that a small, flat, chip-like resistor on it (which is directly to the right of the red IE1394_1 connector and to the left of the northbridge) had exploded, which is now causing my CPU to overheat VERY quickly.
I've been searching around trying to find what the specific resistor was, but I can't find anything. I tried calling Asus themselves, but they weren't able to help me at all. If someone is able to find out which resitor this is (either by finding the answer somewhere or by actually finding my exact motherboard and finding the resistor I'm talking about), and then tell me the exact part number, or the numbers on the resistor itself, so I can buy one and fix my motherboard, I'd be SO grateful to them.

Thanks in advance to anyone who tries to help me.

Gonna solder one on yourself huh? Whelp short of getting a new board not much else to do. I'd just get a new board, but since you're going to try and fix it I'd say try google images and hopefully you can find some hi-def images of the board to help you answer your question.

A close-up photo might help some.

Your description is not much help, I'm afraid. BTW, resistors don't usually 'explode'. If a component down-circuit shorts to gnd., they might crack, but exploding is not likely. Are you sure that it is a resistor, not a capacitor or a diode?

You do have an SMD de-soldering / soldering station, right?

I found a large image of the K8V, and circled and pointed to my guess to which one he is referring to.(i could be wrong)



Unless its the small black one just north of the 1394_1 connector.

croc,
I have seen resistors explode. The first problem is "What failed to make the resistor explode?".

The second problem is that SMD parts are very tricky to replace. You're not gong to be able to do it with a $10 Rat Shack soldering iron. The equipment you need will cost more than a new motherboard.

OTH, there's nothing wrong with experimenting. It's not like you are going to break something. Oh, wait. It's possible that a botched repair job could fry your CPU.

To jsc, thank you for understanding how resistors CAN explode. Now, to cliffro, I don't know how you managed to find such a large picture of the area, but I'm impressed. Unfotunately, you're a BIT off on the part. You can't quite see it from that angle, but on that picture it'd be the small, flat resistor that's being overshadowed by the connector. It would be right where the pin-less hole on the connector is covering from view on the board. The left side (at exactly 270 degrees) of your green circle is going RIGHT over where it would be. It's right between the part you circled and the flat resistor that says, although you can hadly see it, 150 on it and what looks almost like a little bird to the right of the 150. I forget what that type of resistor is called, but I KNOW it's a type of resistor.
I don't know where you found that image originally, but if I could find that image, I'd draw an arrow right to it.

resistors are resistors

its a surface mount resistor....if you can find out the ohmage, you can buy one on digikey, or similar.....but good luck soldering it on there

and it takes a good amount of current to fry resistors....so whatever it was that fried your first one is gonna fry your second one.....

To Joeman42, in the image that cliffro posted, you'll see the item he has circled, but that's not the item that exploded. cliffro is correct in where he says, bellow his image link, that it's a VERY tiny surface-mount resistor just north of the connector.

Now, to uh_no, I've been trying to figure out it's ohmage, but even Asus themselves can't help me. I've searched for a full schematic on the Internet, which would DEFINITELY help me, but I can't find one. If I can learn the ohmage, I'll have no trouble getting a new one and soldering it on. I have all the soldering experience I need, even with surface mount resistors that size, so I shouldn't have a problem.

Now, about your comment on the current frying the second one, you could be right. There's a chance that that single reistor got the slightest bit of coolant on it when I cleaned out my cooling system, and if I missed wiping it off, that would most likely do it, too. If THAT'S the case, then replacing the resistor won't cause any problems. If YOU'RE right though, and I'll admit you most likely are, then it's a waste of time.

This is where I stand now. My computer has been out of commission for TOO long. At this point, I'm ready to buy the identical model motherboard, replace it, and save myself the trouble. Yes, replacing the motherboard will be tedious, but it'll be a good learning experience for me. I'm going to school to learn to be an IT specialist soon, so the work of replacing it doesn't bother me. I'm having GREAT trouble finding the identical board though. I've found the SE version, but I don't want that one because I don't know how it's slight differences will affect everything. I can FINALLY fix my computer if I can just find one. If anyone can find one, or knows where I can find one, and it doesn't matter to me where it comes from, I'd really appreciate it.
