So I had been using my pc perfectly fine for at lest 4-5 months and all of a sudden one day I went to power on my pc and it started up as usual but my monitor didn't display anything. The fans and Lights were running but nothing displayed. If anyone can help I'd really appreciate it because I'm running out of ideas. Here's all of the methods I've tried:
1) Reset CMOS on motherboard
2) Completely replaced my motherboard with a brand new one of the same type.
3) went to a friends house plugged in my gpu into their pc and it worked fine.
4) Bought a completely new power supply and case, prompting me to rebuild my pc and still had the same problem.
5) Bought new dvi and hdmi cables and plugged them into gpu and motherboard but no luck.

My PC specs:
B150 Gaming M3 mother board socket lga1151
Intel i7 6700k processor
MSI GTX 970 Graphics Card
2x8 16GB Hyper X ram
3 tb hard drive

If anyone can help me it would be a lifesaver!
