Computer Not Working

[icebuilder]

I have built my own computer that has been working fine for a year now.
But today after starting the game tomb raider from steam it loaded the game up and then crashed turning off my computer.

Now when i turn on the pc nothing comes up on the monitor.

Following things that are Working:
-Led on motherboard and gpu are both green on.
-fans on gpu and psu.
-back fan that is connected to psu.
-cd drive also working.

Not Working:
- cpu fan not working when booted.
-two fans that are connected to motherboard.
-keyboard and mouse that is connected to back ports of motherboard.
-internet card that is connected to motherboard, light is not on.

Sometimes the hdd light is constantly red.

Specs:
Motherboard: Asus B85M-E
CPU: Intel I5-4590
GPU: Asus R9 270
PSU: Corsair CX500M
RAM: 2x 4GB Corsair
Hdd: 1TB
OS: Windows 7 (64- bit)

Please could someone help.

''cpu fan not working when booted'' does not look good for your cpu ...i hope its not toasted

It might be the motherboard. All the stuff that's not working is connected to the motherboard. It's the only thing I can think of, but it might not be as the leds are shining on the motherboard.

try to reseat the cpu and put new thermal paste ......i do not know if you got the stock or aftermarket cpu cooler?
if after that your pc not run ...i suspect the motherboard like '' aspiring techie '' told you above or the psu

If you take the r9 270 out and start of the integrated gpu does it work?

I got the normal stock cooler that came with the cpu. So i didn't have to put any thermal paste.
how do you reset the cpu?

Yeh i also think its the motherboard but why is the power led on it still working.
No signal is going to the monitor could it be ram or hdd causing problem.

Don't know which component has failed 🙁
