Help please

[just_a_PC]

so I decided as a Christmas gift to build a PC for someone and I have had multiple problems.

When trying to boot it would not start up (the gpu was lit up) so when I went to re do the wiring I screwed up badly. I ended up cutting the hdd LED what should I do will it still Boot. If the led does'nt matter then what could the problem be

The LED is just an LED.  Doesn't matter at all.  Unless the person checks for HDD activity, which I don't even use.  Mine actually isn't plugged in, Only my power LED is

The HDD led shouldn't matter  

 

Do any fans spin up? Display output? No lights or anything? 

 

Try removing all of your ram excluding one stick and see if it boots

The Setup seems to be okay.  If you have another computer, I would try testing individual hardware.  Also, Could it be the monitor or TV? I would test the mobo with a different configuration and GPU and Memory.  Thats why it is always good to test your hardware outside of the case first.  "Your motherboard box makes a great, free, static-free test bench"
