Hey Guys! I'm trying to get this computer working, but it's not turning on right now. It was working before, but it doesn't work anymore. This video below will explain further detail. Thanks in advance!
could be a blown or damaged capacitor on the motherboard, or it could be a defective power connector. If your mobo has a power button on it try using that to turn it on, if the same results are shown try replacing the power supply, if that isn't it then its more then likely the motherboard.
Remove the motherboard battery for a minute and short the cmos pin on the motheboard (read mobo manual). See if it starts after doing that.
I did removed the motherboard battery before, but it didn't do a thing. I'll probably remove the entire motherboard and check to see if there's something wrong.
check to see if any of the capacitors on the motherboard are bloated, or not flat on the top, also look for any sort of residue on them. try disconnecting the power supply and shorting it with a paper clip to see if it turns on, put one end in the green plug of the 20/4 pin connect and another in any of the black pins, if the psu turns on you know that at least turns on. also make sure the power button is conencted correctly and hasnt been dislodged due to any changes you made in the case, you can also short the area where the power button connects with a screw driver or something to see if that turns it on, as it could be a faulty button.
Ah! That's weird, this computer finally turns on when I flip that computer sideway (I'm not sure if that's a case). I didn't do anything to it to fix it, it just magically turns on.
Edit: After few hours later, this computer won't turn on again :(. I have no idea what's going on.
Edit2: Now it's back on again. this computer has been going up and down for some reason.
Sounds like you have a short if you can move it around and it turns on. You can try holding pressing the power and wiggle the parts. The PSU could be bad, but we see a light on the motherboard. The case power switch could be bad, short the pins and test this one. Maybe the CPU or the fan needs to be removed and tighten down. You might need to get your hands dirty and pull it all out and maybe swap a few parts.
im betting one of your wires has shorted in the case, i would take it apart and look for a wire where the plastic has worn off and wire is showing, usually the power switch cable, the speaker wire or one coming from the psu, remove all unnecessary components such as cd drives, extra hard drives and all that. if you have done wire management where you have hid them behind the motherboard that is the place to start looking.
Best thing is to start from scratch, disconnect everything and put the motherboard on a cardboard box, only connect the bare minimum and see if it posts. Then go from there. Also, it sounds like something it shorting out, as if there are no standoffs behind the motherboard.
I found out that if I use the hard power switch off for long time, it "temporary" fixed the problem, and then stop working again after some period of time. I believe that there's something wrong with the psu. I'll try with different psu and I'll let you know the result. Thanks for some tips guys!
Hey guys! Here's a quick update about the problem I have with this computer. This computer only turns on when the hard power switch was off for long time, as I have already said that before. Here's an update video below.
My brother had something like that happen to him with a gigabyte board. So i had him trade his psu for mine and turned the comp on and "boom" the voltage regulator blew up and caught fire. The original psu he had works just fine. The mobo looked fine no signs of any dmg or burn out stuff before i swap psu with him and both psu were in working order and corsair brand.
So i would check the voltage regulators next to the 4 or 8pin cpu power plug with temp sensor. It maybe that those overheated and need time to cool off. Sound like u got the same problem my brother had. If u swap out the psu i recommend a fire extinguisher near by when u turn it on.
