PC Stopped Posting

[Quetz]

So I built my PC on Christmas Day and it's been running great for the past 4 days and when I was on it today I decided to plug my headphones into the front panel of my computer, right when I did this it crashed and now my PC won't post.

If you need the specs they are on my profile page (on my phone at the moment).

I've unplugged everything from the back and taken off all of the front pane plugs because I was worried it could do damage since it already crashed my PC.

Any ideas?

Thanks.

When you say it can't post, do you mean that it wont boot into Windows or the whole computer itself wont turn on?

Everything in the PC turns on, CPU cooler, GPU, network card, and PSU fan turns on but nothing on the screens. Already tried two different display cords on two different monitors.

Could be a dead gpu, although you would need to borrow somebodies to test it.

I took my dad's GPU and put it in both of my PCI Express slots and it still wouldn't show anything on the screen. So do you think this is the mobo?
