3 years ago#1
Hello guys. I'm building my first computer from a few parts I bought and a few I scavenged from an older computer (maybe 2 years old). I managed to place everything into the case and to my best understanding everything is hooked up correctly to the motherboard. The only cables I'm unsure of are the LED ones that the case brought and the ones that connect the POWER and RESET button to the motherboard (all these are 2 pin connectors and maybe one 3 pin and nothing really looks like them in the motherboard). Anyway, I plug the PC in and before even doing anything, the motherboard turns on a small orange light. I press the power button and absolutely nothing happens. And that's what's killing me. I have no idea why that's happening or what to do about it. I have tried to reconnect all the cables but nothing changes. So I turn to you guys who are most likely a LOT better at this than me. Any help would be greatly appreciated. Thanks in advance.

I'm a little confused by your post. Did you actually plug in the cables from your case into the motherboard? If not that's why the button isn't doing anything.

You should see on the motherboard where to plug each cable in. As to which is positive or negative you might have to just try both to see if either works.

I did plug everything (no unplugged cables).

Read the motherboard manual, and it will tell you where the power, reset, hdd indicator, etc should go. Although, most motherboards kinda have that section all labeled out on the pcb.

That little light probably means the mobo is in standby mode so at least you know you didn't forget to turn on the power switch on the back of the power supply.

Those little cable connectors sometimes aren't clearly marked in which way they need to be inserted into the pins. So pull the power one out, remember which was it was oriented, turn it 180 degrees so the holes are switched around and plug it back in..

Thing is that the motherboard is one of the parts I took from another computer (that other computer was still working and in use up until I took it apart) and I have no idea where to find that manual. I have looked online for it (it's a DELL) but all I get are links to buy it.

Next to the front panel connector area there should be a part that says what each pin is. If your power button is 2 separate plugs you might have put them in the wrong way and need to switch them.

Okay well question, what are the parts you are putting into the new build?

All I can see near the front panel are the labels for 2 USB ports, MIC and Headset. Near the power button there's only the buttons and cable with a P next to power and R next to reset.

EDIT: I found the diagram for the motherboard. I plugged all the little cables to where the "front panel" things go but still no luck. Is there a particular way to plug those in or just plug them as long as they fit?

I am putting a new PSU, a new Graphics card and more RAM

They should just fit, there is no right way to plug it in, just as long as it plugs in. Stupid question, but are you using compatible parts?
