Now one last thing, Here's what got me kind of stumped. I was connecting wirings and cables etc.. I know for a fact that I never seen that before so I did a little research in hope to find the answer what it was for and still cannot find what that is for. Hope you can help me with that last puzzle.
Catweazle, if the red fiber washer is on the top side of the mobo, under the screw head, how can it ground properly? The yellow wire is used to monitor fanspeed.
Can't help you until I know where that fan is located, I'm afraid. Another point. Use the commonsense approach to connecting and testing. If you connect everything at once, and it doesn't work, you can spend ages of trial and error to find the problem ;. Its from the case fan, coming out like those wiring for power etc.. Seeing it has like 2 yellow wires and 2 black wires all connected to one connector? What sort of connector?
Molex, 3 pin, what? Has the case you have got a front or rear fan controller? A monitor panel? Bit hard to answer your question, I think, as that wiring does not follow any standard scheme.
Let me see if I can take a pix of it and attach it in here so U can see what I am talking about ok. Hi, It dont have any controller on this case. Here's the pixes. Hope it helps and that you can see it clearly. That lead and connector is coming from the power supply unit, not from a fan, isn't it? Tuck the thing away somewhere out of the way and forget about it, unless there is a relevent socket on your motherboard for it.
Some motherboards make use of the connector to supply extra power for fans, etc. Some don't. If you don't need it then don't use it :. Hope this helps. That's a P4 12v power connector. Since you don't have a P4 system, then you can do as Catweazle suggested and tuck it away. Thats what got me stumped. I'm guessing its for something like fan cooling monitoring or something?
Ok Gtreat! I like to keep things tidy as well. I'm going to double check everything and make sure all is well before turning on computer and I'll let you know how it goes in little while. HI, Not looking good here. When I turned on the tower, I see led lights coming on etc.. Hi, I took out those red washers and set the motherboard on anti-static bag and tried to see if it CPU fan spins and it didnt.
I am thinking of it could be bad power supply? Or Do I have to reset the jumpers on mobo? Check, recheck and double check the front panel connectors. Nothing else fitted or connected to the motherboard at all. That's a 'bare-bones' configuration. If the motherboard has onboard video, use that rather than an add-in card. Hook up the keyboard and monitor, power up, see if it POSTs. If not, check the front panel connectors again.
Yeah I am going to double check everything. Yeah It's a barebone kit. It has onboard video. I was thkining that it didnt matter if wires were reversed or not. It'd still work? I also am going to recheck the jumpers on mobo to make sure its right settings etc. Not much there to check actually lol but gonna do it anyway to make sure. The correct screws will not have a flange around the head.
Zorg Splendid. May 31, 6, 0 25, 1. Agreed, skip the washers. Thanks guys! Maybe those washers were for something else, but I'll be skipping them since you do too. My screws are indeed not flanged as you said whiznot. Very flat on the top. May 6, 0 18, 0. Some cases have an extra grounding wire that you can attach to one of those screws; I've seen this for the upper left screw.
Mar 8, 1, 0 19, Yup the washers aren't necessary, just make sure that you use the small button head screws rather than the ones with a flared base and that the screws are long enough to get a decent bite into the standoffs that are screwed into the case that the motherboard will rest on. I guess some motherboards have special grounding requirements. I just turned on my system for the 1st time and went into BIOS successfully.
No HD's yet, but that's next. So it looks like it's running good at this point with no washers. Thanks for the tips aziraphale, and boonality. Kari Splendid.

The moboPCB is likely a multilayer board and there's a separate ground plane inside the board.
Normally there shouldn't be any meaningful currents going through those screws, the ground plane is mainly meant to give stable groundlevel for the datalines and thus reduce crosstalk between the lines and to reduce other interferences as well. It'll work with the washers and outside the case aswell though, so it's not criticall as such, in those cases the ground plane is left floating in some not-so-well defined potential and it will likely decrease the boards resistance to outside interferences and lower signal-to-noise ratios for the datalines.
Might have some effect on the max overclock the board can handle as well. Or at least that's how I've understood it.. Bache Distinguished. Dec 3, 0 18, 0. Use the screws supplied with MB or other small head screws. The screw head should not exceed the size of the "metal surround" of MB hole - should be smaller. If it does, it could possibly shortout or make conductivity with other circuits near mounting hole. The MB manufacturer would not use conductive material around hole if elec connection to case avoidance was a issue.
If it was, insulated tubes plus washers would be supplied. Nov 12, 0 18, 0. I've got the as well and got some of those paper washers for my i I think you would need them if there wasnt any metal around the holes on the motherboard this seems like it's for grounding.
But yeah, just make sure you tighten up the standoffs before screwing everything down; last think you want is for the standoffs to be turning instead of the screws when your trying to take the mobo off May 16, 8, 0 31, The screws do ground the motherboard. But they make ground contact where ground contact was intended to be made. The holes where the screws go are isolated from the rest of the components on the board.
The washers supplied are intended to be used to mount the board. They are not for electrical insulation purposes, I don't know where everyone gets this idea from.
If supplied, I use them, if not, I don't. Either way, if you follow directions and place the proper number of standoffs in the correct places, use the correct screws, you seldom have any problems.

The washers allow you to cinch the board down snugly without pinching the board. Also, they allow for a small amount of vibration to be absorbed without loosening the screws - and decreasing the noise from the system. How much noise you ask? Risk Factor: Moderate to High. It's pretty easy to not install the motherboard properly, which can result in spurious operation or even hardware damage.
Phillips head screwdriver. These should come in a small bag with the system case. See this page for a full description of this hardware. Wire snips, knife or scissors. This corresponds to the size used by the metal spacers that go between the motherboard and system case. Otherwise, you'll need a pair of needle-nose pliers or similar. Software Required : None. Time to Perform: minutes, assuming that you don't have too much trouble getting the board to fit. There is a very high degree of variability in motherboards and cases.
It's not too likely that your hardware will match exactly what I describe in this procedure, and in particular, there seem to be no two system cases that are alike. So stay on your toes in following these directions. Be very careful when physically manipulating the board not to bang it or any of the components on it, into anything.
Handle the board by the edges. If the system case has a removable motherboard panel and most newer tower cases do then remove it before beginning this procedure; it will make your life a lot easier. The steps below are geared toward either a direct case installation or installation to a removable panel.
I would strongly recommend against installing the motherboard into the case if when you are finished, the board is not firmly supported in at least six places around the board, including at least one point in the center. If the board is not supported properly, the chance of damage later on is very real. When you are finished with the installation, check under the motherboard for loose screws or other hardware; you definitely do not want these left inside the case!
Orient Case or Mounting Panel: Arrange the case or removable motherboard mounting panel so that the the expansion card slots and keyboard and other connectors are farthest away from you. For the rest of this procedure, I refer to the the edge of the motherboard where the connectors go as the "back" of the motherboard.
Find Motherboard Mounting Holes: Examine the motherboard and locate its mounting holes. These are usually found as follows: One row of three or four holes along the back of the board, where the expansion slots are. A second row of either two or three holes somewhere in the middle of the board. These may not all be in a straight line. A third row of usually two holes, but maybe three, along the front edge of the board. You will generally see the following: Threaded screw holes: These are small screw holes that are intended to take screw-in metal standoffs.
All cases have at least a couple of these; some have more than others. Eyelet holes: These are large, oblong holes about an inch or so in length that take the sliding plastic standoffs. They are narrower at one end than the other. Some cases no longer use these at all.
