new PC won't start - wiring problems?

EMachines are already DOA at the retail shelves let alone when you get them home. :P Those have to be the "worst" cheapest built rippoff there. :rolleyes: Drop it in the nearest recycle bin and call it a night there. :D
 
Emacines...sure, but i didn't buy an emachine mobo. Sucks. I got my own pc and some other stuff so I'm good, but I love fixing up stuff that doesn't work too well, but this one....well as you put....I will probably trash it, or something really close to that effect and call it a night......see ya'!
 
During the late spring a friend asked why his new build wouldn't run and upon looking everything over the board become the focus. The vendor sent another of the same model and that saw the same problem. When you threw on the breaker switch on the supply the drive lights gave a quick flash and then nothing. When the idea of trying a different model or make and model was suggested another model was sent out. It has been running good ever since then. With no beep codes being heard the board is usually toast.

If you saw a flash when pressing... but did you try holding in the power buttom for a few seconds more? If you just quickly pressed the button a brief flash of one of the drive lights would indicate the switch is good. But you may have to hold it in a few seconds longer?

Yeah I tried that. If the PSU were defective, would it even make a flash like that? I hope its not my mobo. Is there anyway to specifically test my mobo, or just process of elimination?
 
Try another supply or try the supply in another case. Those would be the first two things to test that out. A flaky contact wouldn't account for a failed start after several attempts. If you jump the pins for the power switch and still don't see it do more then flash a drive light and no audiio alerts or onscreen messages like failed cpu come up the board would be suspect.
 
You first have to which two pins are for the power switch on the block. A simple papre clip or even a small flat head screwdriver is all that is needed to touch both pins at the same time to make the connection. That closes the circuit there. Just be careful what two pins you actually touch there to avoid a crosscircuit or short from occuring.
 
well.. if the mobo wasnt jacked up before, it is now.

I decided to use a PSU tester to see if the PSU was functional. So I plugged all the cables into the device (20-pin, 4-pin, etc). But guess what, I forgot one of the four pin sets was still plugged into the motherboard. Flipped the power switch on, heard a loud "POP" and started smelling smoke. One of the little cylinders on the mobo completely exploded. But the good news; my PSU works haha. I don't feel good.

Is it possible to replace one of the cylinder things on the mobo? And I still don't know why it didnt work before i nuked the mobo.
 
You whaaaa...t! :eek: I thought you were going to try jumping the two pins not cook your goose there! Capacitors can replaced by an experienced tech only. But you have to know the exact value of the cap you just launched into.... OOOO... blivvv... viviviv...iiiiii onnnnn along with being able to get the replacement. Besides wiping the cap you may have damaged something else. :(
 
You better hope that the cap there acted like a fuse and took the load direct. The only way you will know if those were hurt although not that likely would be when they were tried out on another working board.
 
You may want to run memtest or another memory diagnostic tool to see if errors come up. If that's a pair of 512mb dimms try each separately. If the memory or cpu was cooked you'll know right away with the beep codes.
 
Well hopefully you will have a good report on the memory and cpu there. Just make certain to unplug "everything" if and when you use a supply tester again.
 
ok this is driving me nuts. I hooked up all the stuff to the new ASUS P5B board. The LED light next to the front panel on the mobo lights up, so power is getting to the board. I tested the PSU again and it's giving power. What else can i test? No beeps or anything when i try to power on.
 
Swap it for another model if that was a replacement under dealer warranty. This is starting to sound like the same crap a friend went through when two identical boards in a row were doa. Upion the vendor there sending out a different model everything fired right up normally and has been running strong since. If you double checked all connections with a fine toothed comb then you are looking at another bad board by the sounds of it.
 
If you are not hearing any beep codes for anything like a failed video card, memory, or dead cpu you probably received a bad board. The one thing I could highlight again is going back over the wires from the front panel just in case.... ? It only takes one goof there with a mixup of two wires to stall everything. Have you tried jumping the pins for the power switch to see if that happened? Hopefully it will be something simple like that.
