View Full Version : Knocked off a Couple Resistors - Should I Worry?

I had knocked off a resistor a while ago because of the washers that I put on for my heatsink. It ran without a hitch, but I had to take off the heatsink again cuz the voltages were freaking out again and it looks like there's another resistor that's hanging loosely. One of the contacts is still connected, but it's dangling around. Will this impact my motherboard in a negative way?

It can't be helping things. If everything still working then I guess it's too late to make a difference now.
hmm............... just solder it............
Wait, is the resistor the smaller ones? then it hard to be soldered........ in that case, just use the heat gun......
Or go with the ultimate solution : RMA :D

Is RMAing something I can do for the life of the product or is it only available for a certain period of time? I just went ahead and took the resistor off. I'd rather have no resistor than a dangling one. This wouldn't have happened if I didn't take the heatsink off, but the voltages started going screwy again and I decided to take off the back plate and just screw the heatsink into some nuts. I hope it helps. I don't get how a heatsink could possibly affect the current flow. I'm sure that it's the heatsink because the computer started going crazy after I installed it, but it doesn't make sense cuz I have it away from all the electrical components using plastic washers.
ouch............. i tought you just bought the motherboard...........
Anyway, that resistor is there for some reason, its best to find a way to reattach them!

It's definitely there for a reason, unless some bored engineer/designer felt the need for unseen bling bling... Maybe it's time to ebay it "as is" and look for a new mobo?

LOL You guys go through motherboards like they're blank CDs :D I'm definitely keeping this motherboard. It's just a small resistor so I'm sure it won't affect the voltages too much. I'm gonna try to find the max overclock again after I get everything working. I had to lower my overclock because it was getting too hot at 2v, but I'll try to squeeze a little more outta this before I upgrade.

the caps and reisitors around the cpu are most likely a part of the volt stablity curcit
so it could work without them if you are luckey i would worry though
here is how smd reisitors look like

some resistors are used to bias the circuit either high or low, some are actually zero ohm to tie things to ground. If you knocked off the resistor you should check it with an ohmeter, if it's a zero ohm resister then you may have left some signal floating...
That's what happens when you see outrageous readings for sensors some times, they don't bias an unused input into the hardware monitor...that gives phantom readings.
SMT is a bugger to re-attach, but it can be done...

hmm, I just replaced the heatsink back plate with some nuts and washers and now the computer turns off immediately after I turn it on. Do you think that one knocked resistor could possibly screw up my motherboard that much? If not then it's a short, but if it's something to do with the resistors then I'm kinda scurd cuz I lost one and dropped the other so I couldn't reattach them if I wanted. Can I buy those kinds of resistors at a local store if worse comes to worst?

Could do..
As an example..
I was putting a test point on a circuit board, I got my iron too close to a very small smt resistor and popped it off the pads.
That resistor went to a crystal for one of the clocks on the board.
No clock signal = no go on that board...it would post but thats about it, as the diagnostic LED's indicated.
Once my co-worker put the resistor back on, we applied voltage to the board and it fired right up, no problem...
You could be looking at the same thing here...something is looking for a signal, but is not getting that signal.
Good Luck

If you just put the backplate on with some nuts and washers there's a good chance something is shorting out. Try to reinstall the back plate and make sure none of the washers or nuts are touching something they shouldn't be. I've seen weird problems due to that happening before.
-Or what MD said :p
I wouldn't worry, if you knocked them off and didn't notice any difference, then they were probably regulating voltages for part of your mobo you dont use, like maybe unused SATA channels or USB. When you plug in your 4th SATA drive and it fries out from voltage overload, you're going to regret knocking those off! ;)

lol, I just tested my motherboard without the CPU heatsink and only the ATX and 4 pin motherboard cables attached and the board immediately shuts off after a couple seconds, but I can see that the northbridge heatsink is trying to spin. Earlier, the northbridge fan was completely dead so that means that the first resistor I knocked off killed the NB fan, but then knocking off the second resistor brought it back to life, somewhat. I'm definitely gonna have to RMA this board :( I think Abit still lets people RMA their boards even after the warranty expires, albeit at a small price, $20 I believe. I wish I could just sell off these parts, the ones that are working, and upgrade but I'm saving up for a motorcycle so that's out of the question.
hmm..do you have a ohmmeter? and the two resistors still?? its a good idea to mesaure it and get two sprares.......

I could use a voltometer at my school, except I'm just now remembering that I'm on summer break *slaps forehead* :rolleyes: I don't think they have ohmmeters though. Those resistors are gone anyways. The first one I knocked off I just tossed it into my carpet cuz I didn't think I'd need it and then the second one, I decided to keep, but I nudged the motherboard a little and it disappeared somewhere. I'd rather have a new board anyways. I scratched the PCB in a couple spots because I was trying to slice off the tip of a solder joint that looked like it was making contact with the heatsink back plate. Even if I did get some spare resistors, I have absolutey no idea how I'd solder it on in such a cramped space. Honestly, I don't think it can be done with a soldering iron, at least by me.
I sent Abit an RMA request today so I should be getting a reply pretty soon. They have a very good RMA service in my opinion.
