My custom pc is not starting!

AlleLalle · Aug 15, 2014

Im done with building my first pc, but it wont start. The motherboard led's light up, but when I press the power button nothing happens. I dont know if the power supply fan even starts. Please help ;c

Ok, check all these things first and after that come back and let me know what you found. I'm guessing right off the bat that you might have forgotten to connect the processor 4 or 8 pin power connector that plugs in next to the processor but check this list first and then let me know. There are two power plugs that connect to the motherboard, in case you missed that.

Did all that. When i hold the power button on the motherboard/or the chassi for like 5 secs, a blue led starts blinking just above the motherboard battery. So I know the chassi also gets power but nothing will start up. ;c

And you have the cpu 8 pin connector plugged into the board next to the processor as well as the 24 pin by the edge? And are you sure you've got the system connectors on right that come from the front panel power button and reset? For sure? Heh. It's very easy to make a mistake with the tiny system pins.

AlleLalle · Aug 17, 2014

the 8 and 24 pins are in, the im sure the small connectosr are done right since I did it twice. The chassi GETS power but doesnt power on ;c Really dont know what the blue blinking led is for :/

thanks for your help! really hope it will work ;c

what's the model number of your Vengeance pro RAM so I know the speed, timing, etc.?

Darkbreeze · Aug 17, 2014

Blue blinking light is supposed to be BIOS in operation, BIOS A.

What do you mean you don't know if the power supply fan starts? Can't you see it or hear it? Take a look and let me know. Also, if the case fans and cpu fan are running. This thing might be running and you just have a display problem.

Darkbreeze · Aug 17, 2014

Also, make sure the RAM modules are not installed in side by side slots. They need to be in slot 1 and 3, slot 1 being closest to the CPU. Or if only using 1 module, for testing, in slot 1. I would recommend you try that and if it doesn't work with one module, swap it out for the other one.

2 ddr3 vengenance pro 2X4 gb 1660 mhz, slots are right, power supply fan is on. Will try the ram one by one thanks. No other fan is running. Not the cpu fan either ;c

Darkbreeze · Aug 18, 2014

You do have the case fans and cpu fan connected to the motherboard right? I know, a stupid question but I have to make sure.

Darkbreeze · Aug 18, 2014

It's sounding a lot like a motherboard issue but let's see what happens with the RAM.

grimmjow660 · Aug 18, 2014

Try pressing the Motherboard power button on the top right.

Darkbreeze · Aug 18, 2014

grimmjow660 :

Yeah, that's helpful.

grimmjow660 · Aug 18, 2014

Darkbreeze :

Can't tell if that's sarcasm or not. But with my Asus board I has the same problem as he described, I hit the motherboard power button and everything has been fine

Darkbreeze · Aug 18, 2014

It wasn't sarcasm. Literally, it would be helpful to hit the motherboard power or reset buttons located on the motherboard itself.

Darkbreeze · Aug 18, 2014

Should have thought of that to start with but it's not the first thing you think of on a motherboard is there being any functional buttons on it.

Vic 40 · Aug 18, 2014

He already tried the button on the motherboard,

AlleLalle :

It's not what you want to hear,but rebuild the whole pc and recheck every detail.Maybe even do a clear cmos.
You could even try the components outside the case first to see if they work there to rule a short circuit out.

Darkbreeze · Aug 18, 2014

Hmm. Kinda goes with what Vic 40 is saying, but make absolutely certain the 24 pin ATX and 8 pin cpu connectors are all the way down on the board. I've had these connectors look for all the world like they were in all the way before and then pulled them off and clipped them back in and BAM, good to go. It's worth trying at least after you try the RAM. Also, try the RAM individually in each slot. Could be a bad slot too.

AlleLalle · Aug 18, 2014

Thanks everybody, really concidering to rebuild everything again :/. I did putting the 24 and 8 pin connector again, nothing. Tried both rams seperatly, nothing ;C

Vic 40 · Aug 18, 2014

AlleLalle :

You mih\ght have missed something so imo a good idea.Let us know if it works.If not an rma is probably necessary.

AlleLalle · Aug 18, 2014

is it possibe that 600w wasnt enough btw`?

Vic 40 · Aug 18, 2014

No,600watts are more than enough.The cx series is not their best but should be good enough.
What you could try is ruling it out by trying with a psu from another system,maybe from a friend or ...

AlleLalle · Aug 18, 2014

Really wonder what the blue blinking led is for, because as said it always starts up when I hold the power button for like 5 secs ;C

My custom pc is not starting!
