My pci express network card can't be read?!?

[josephtito19942]

I have a motherboard intel DG41RQ and it has a built in lan card but i wanted to put another lan card via the PCI express slot and i put it and the flash lights on the network card are flashing but still the hardware manager and everything on the computer haven't even noticed that i put a new hardware, and that is really driving me mad. any help plz

Don't worry, I've built hundreds of machines and never had a motherboard go out if I received it in working condition from UPS, so it is very likely something minor.

The HDD light requires that the two wire connection to the motherboard is attached -- check to see that it is not loose.

Now when you say nothing happens -- do you mean absolutely nothing, no indication of power at all? If so, you need to check the breaker to the receptacle (like plug a lamp in to the other half of the receptacle), then check the PSU 20/24 pin and ATX 12V 4/8 pin connection to the motherboard.

By nothing happens i mean no voices and nor the beep of the startup only the fans are working and the lamp on the motherboard, and i don't understand wt i should do to make sure that the motherboard is ok

Really the only way to test the motherboard is to step by step try different parts, but that would be the last thing that I would try.

With all the work you have done there may also be a short under the board from it touching a part of the case somewhere -- I remove everything and do a bench build on a sheet of cardboard to check that and also it is a chance to remove and replace all the parts and cables carefully to insure good connections. In fact I assemble almost all my machines that way first to test them and then put the build into the case.

 

[josephtito19942]

Ok i will try that and give u the news as soon as possible.

 

[josephtito19942]

I tried everything, i removed every peace and i de-attached each single wire and cleaned everything and i also i tired to start the pc outside the case on a carton and still nothing changed :S

Sounds like you need someone to actually look at the build with you -- preferably someone with significant troubleshooting experience.

Here are a few other ideas -- but do them carefully ONE at a time to isolate the issue.

If everything is properly attached and connected, and you have removed any unneeded parts (like the extra LAN card) I would start by using a single stick of RAM in the first slot and go through all your sticks to see if one has a short.

I would also remove the graphic card and try using the onboard graphics.

Then I would take my multimeter to the PSU to insure that the power and ATX12V 4/8 pin are working. If you haven't done this before have someone help you that knows about this.

OK i did everything about the ram and the VGA and still the same but i dont know how i should do that thing about the power supply.

 

[RealBeast]

Since you had the three beeps from the memory before you removed it but not after, I suspect that something is wrong there. Can you test it in another machine?

Couldn't hurt to clear the CMOS with the jumper again, and then return it to the default (usually 1-2) position.

 

[josephtito19942]

I cleared the CMOS and still nothing and i have 2 rams so i tried each of them without the other one but on the same machine because i dont have any other to try on and still nothing so i dont think the 2 rams broke down together!

 

[RealBeast]

You can also try another ram slot if your board does not require one in the first slot. No, unlikely that both sticks went bad.

 

[josephtito19942]

I tried each ram in a diff slot and still the same.

I just want to point out that I had a very similar issue with a GTX 660 on a desktop these past two days, losing the whole days researching on what could be the issue.

The issue as often happens with issues was closer to home than I thought it would be. All I had to do was make sure the graphics card was clicked into place, that I heard that damn click of the graphics card getting inside the latch and the latch closing in on the gpu.

A few weeks earlier, I had the very same issue with the RAM, and it just didn't occur to me that this was what was happening with the GPU. It was only when I saw the latch close in on a much smaller GPU I was putting in there to split test to see if it was the 660s fault, and then I thought oh shit, this could be it, and sure enough it was. But that doesn't take back the two days of my life down the drain, nor does it take away the two days a couple of weeks ago I spent researching about the RAM, so be warned people, make sure these damn things latch in to save lost time.
