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.

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.
 
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.

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

He already tried the button on the motherboard,




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.
 
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.
