PC doesnt boot.

[thepsycho24]

Specs:
Msi z370 Tomahawk.
i5 8600k
Corsair VS 550
8gb ram ddr4 ballistix sport
Asus dual Gtx 1070 

Built PC. At first, it powered on, but ut did not display any image, but all the fans were spinning. The CPU Debug light on the MB lighted up. We powered it on about 3 times, then it suddenly shut down, and we coudln't manage to power it Up since then.
Things we tried since than.
-) removed the GPU
-) unplug all cables except CPU power and Mainboard power.
-) removed Mainboard from case, tried to boot it on cardboard, no luck.
-) tried ram on different slots.

Maybe it's a bad CPU?

 

 

 

hence the fucking cpu light

if you build a pc always try to boot with less attached stuff as posible so you know more quick were things go wrong.
Videocards wint need often, you can use internal video this ensure the most stable setup to see if ram/harddisk /cpu/ psu
is working as it should.
It sucks to unbuild a complete case if something fails, just to try finding the fail.

Try reseating the CPU, also make sure when putting it back together that the CPU cooler has a good connection to the CPU (watch the thermal paste application and such)

If you're going to be rude to someone, how about not responding at all?

I didn't mean to be rude, it was a "no duh" statement.

Maybe, but we don't even get to the point where the cpu light lights up anymore.

I don't know, if i remove the cpu and the cpu fan, can i "power up" the Mainboard itself?

I mean generally, do mainboards support that?

I'm not sure. Just try.

So big update. Mainboard without cpu powers on and Blinks red. Reassembled with CPU, doesn't power on. Sooo... My cpu is defective... Right?

Is the CPU heat sink fan plugged in?

No, it wasnt at the last try, but all before. Should that affect if the pc starts "at all"? Right now, it is doing literlary nothing when cpu is inserted and power is pressed.

In theory it should in order to keep the CPU from overheating, which is why it is likely not meant to turn on without a fan plugged into the CPU's header...
