Computer not turning on, need help

post #1 of 17
Thread Starter 
My computer isn't turning on. There's a blue LED on my motherboard that lights up. It continuously lights up. When I press the power button, my computer turns on for a second, then turns back off. I know it's not the PSU because I replaced my old PSU with an XFX 850w Core Edition. I did a rebuild in a new case (HAF 912), so I can't imagine what the problem would be. Does anyone know what's going on or any advice?

+Rep for anyone who fixes this

Could you make a Tried list please? so people don't suggest things you've already tried ^^,

Have you checked all connections internally on the board? and reset your CMOS?
Are you using an extension socket? adapter etc? check those aswell.

Hopefully it wasn't an electrical short/surge that damaged the board. And just between you and me, its not good form to pre-offer rep for answers, theres no need, we'll help anyway
Edit: does it give you a beep code?

Check power cable is in properly, check the power connectors to the mobo are in properly. What exactly happened to make this happen?

Assuming you didn't do anything obvious like not use standoffs to mount the mobo or forget to connect something (protip- double check!), remove everything except the CPU/heatsink and 1 stick of ram. If you still can't get life out of it, something's broke.

Edit: also, in my experience clear CMOS doesn't always take. Read the mobo's instructions and follow them, and leave the jumper connected for a minute or two.

Actually that reminds me; I had this happen once because I'd left the jumper in the clear cmos position. Check that.

I tried resetting the CMOS through the battery and by the button on the I/O shield side of the mobo. I also am pretty sure nothing is plugged in wrong.

This is a long shot, but pick up your case and gently tilt it to test for any lost screws inside that could be shorting the board, sounds ridiculous, i know, but i've seen it happen, might as well get it out of the way.

Then disconnect everything external from the machine, and reseat all componenets (you can leave the cpu) eg: GPU, RAM, check HDD connections, and check for any black marks on the board (assuming the board is not a black colour lol)

I don't have the old PSU anymore. I don't think the new PSU is faulty.
