My newly built PC boots up fine but there is no display(No DVI or HDMI signal). The motherboard turns on(lights are on) but when I left the GPU in and took the RAM out, there was no beeps. Just to test it out more, I took out the GPU, RAM stick, and unplugged my hard drive and there was still no beeps(speaker is plugged in). In addition, I think I may have damaged the motherboard screwing in the stock AMD cooler, creating holes outside of the suggested two openings. I checked my GPU on the bottom and some "circuit pins"(idk what it's called) are bent I know my motherboard is working to an extent(GPU fans still spin + the lights still turn on). Also, I left my RAM stick in but unplugged the PCI-E cables on my GPU and I got the beep code for GPU not working. I have tried reseating the RAM on all four slots, turned on PSU, made sure all cables+cards sat flush, made sure I connected the right cables to the proper places, set it to correct input, tried both HDMI and DVI, and still nothing. Also, should there be standoffs attached to my case/motherboard like so (

make screwing in the AMD wraith stealth cooler easier because my motherboard did not come with any. Any advice will be greatly appreciated and I will clarify anything that needs to be clarified!
