also the psu that comes with acer aspire is weirdly wired onto the case.
This is a non issue if the cables are long enough. You just need to connect the 24pin and 4pin for the CPU.

Of course make sure that everything from the new power supply is disconnected.

Not working

Changing power supply doesn't work. I plugged in the 24 pin and cpu pin but not working

You very likely fried the motherboard, I don't how. The pins of the power connectors have different shapes, which means you can't connect it the wrong way. The front panel was connected as should as well.

At least you can check if the PSU is working, as you didn't have the chance to test(I assume you bought the EVGA one:

Anything specific you think you could have done that may have damaged the motherboard?

Also re-check your connections. Plug everything out and back in again.

What are the signs of a fried mobo. In some cases I pushed hard enough to hear creaks. Now it's nit cracked but when I was scrwwing in screws I would hear it slightly creak. In some rare cases my hands may of accidently touched the capacitors as I was plugging wires

I haven't taken out the cmos battery. I'll try that with my professor just in case I mess up. Thx for help anyways

In many cases there are no signs that can be easily spotted, suggesting a fried mobo. I doubt the issue is because of tightening the screws too hard, but always tight the screws with wrist strength, not using the whole arm. This way you will be sure that you didn't over tighten.

I left my mobo out for 24h

Inside an open case

That shouldn't be a problem. There are people(extreme overclockers) that put their motherboards in dish washers to clean the vaseline off from it and after that the motherboard works just fine

. Don't ask why you would put a vaseline on a motherboard, because it is long to explain

.

Whether the motherboard is in a case or outside it is pretty much exposed at the same environment either way.

Do I need a thermal paste? Or does that not make a difference

ven98 · February 15

You definitely need a thermal paste, but that is not the reason why the motherboard isn't working.

Saliwarrior · February 15

I mean there's already thermal paste inside of it from two years ago and I didn't open the heat sink. Shouldn't it at least operate and turn off a few secs kater

Saliwarrior · February 15

Oh okay. Makes sense

Saliwarrior · February 15

How could you tell that I need thermal paste. I've no clue?

ven98 · February 15

In your previous post somewhere you asked whether you have to remove the fan and said you had no thermal paste. I thought you didn't have thermal paste on the fan, as you have removed it previously. It seems you have thermal paste, so you don't need to repaste, but if you have removed the fan without changing the thermal paste, then you definitely have to change it.

Just curious. I did push test and it worked. I plugged everything into motgerboard but not a single component responded. Not even the power supply? What could be the cause of this

Saliwarrior · February 16

I meant psu

The motherboard is likely to be the problem. When you press the power button it triggers a change of state of other circuits in the motherboard, which can be where the problem lies.

I never thought about that, but it is possible, very rare probably, but still possible that the power button itself could be the problem. It is very little possibility, but still worth troubleshooting. You can use the multimeter to check the resistance(in ohms) between the 2 cables of the power button(PSW or PW), in 'pressed condition'. If it shows a value close to 0(e.g 0.1ohms), then the power button isn't the problem. Your other option is to use the power button of the GX-781 case. To do so find this connector in the case(see picture) and connect to the motherboard and then press the power button of the GX-781 case.
