Killed some resistors - repairable?

[JMU1337]

Got a replacement motherboard a few weeks ago since mine was crapping out, but in my haste to uninstall the cpu when the new assembly didn't work (long story short, my mobo wasn't crapped, my psu was) I ripped through some small resistors with a screwdriver (damned Athlon XP heatsink design). I've since gotten another motherboard and all is fine, but should I just trash the ruined mobo? It's a fresh Asus A7N8X-X...

Try if it works without, if yes, you're lucky, this happened to my graphics card too.
If it doesn't work, you can solder it

I doubt that it can work without transistors, specially the ones near the processor area.

You can change them... IF you have a good soldering machine, and find the resistors of identical capacity... you should be able to have it working in no-time. You need *good* pulse.

I broke 2 transistors of my graphics card, but it still works

@topic or use the warranty

He said RESISTORS not Transistors

how do resistors work? is the electrical current just affected by the material or do they actually have "stuff" inside them? meaning if they are still there (somewhat) and connected to the board/lines appropriately they still function?

i need to pick up another psu and test this out

Resistors limit the flow of electricity and are often used to reduce voltage. The inside material is most commonly carbon, but other more exotic (and expensive) materials like ceramic are used when a higher tolerance is needed. On a resistor you will see several differant bands of colour, they each reperesent a number that adds up to the number of OHM's of resistance. The last band on the right side (when reading it from left to right) is the tolarance spec. Tolarance means that the resistor is with in a certain percent of the specified number of OHM's of resistance. The tighter the tolarnce the more exotic and expensive the resistor. Most commonly you can find 5-10% (TOL) for cheap and much more precice 1% or less will cost a lot more.

here is a colour chart for resistors and an explanation of how to read them

Tolerance Colour Code:
silver 10%
gold 5%
red 2%
brown 1%.

Yeah yeah I understand the bands and all, but I really didn't pay attention in my electrical class in college. Does a resistor function based on the total mass of the material or just the consistency of the material? Does a bigger resistor (physical size) made of the same material resist the same amount as a smaller one? I didn't totally destroy these things, just put some gouges in them...

Correct.



Depending on the type of resistor, you might be able to replace it.
