Hi, i’ll start off by saying this is the second PC i’ve built. I built everything inside the case and tested it out with a monitor and keyboard, all connectors were in the right place and everything was running like it was supposed to. The keyboard and mouse would turn on and all the fans would run… but nothing came up on the screen. I then rebuilt it outside the case and, received the same results. I decided to go back and re apply thermal paste and re attach the cooling unit because I felt I had previously done a poor job and thought that might be the problem. I discovered that I had put way too much thermal paste (Arctic Silver 5) on and that some of it had seeped off of the sides and onto the pins. I initially tried to dab a microfiber towel onto the pins to get the paste off but that just ended up bending the pins. I then cleaned out the pins with a toothbrush, magnifying glass, and alcohol as well as bent the pens back using some tweezers. I looked up to see if my paste was electrically conductive and it is not so I went ahead and reassembled the cooling unit and the rest of the pc (outside the case) using less paste this time. I have tried the graphics cards in both slots as well as testing a second graphics card. The graphics card’s fans, in both cases, started upon boot and then stopped. It is my understanding, though, that most graphics cards these days don't start to use their fans until they need to, am I correct in this assumption? I’ve tried all different combinations of ram slots, i.e no ram, 1 in the A1 slot one in A1 and B1, one in A1 and A2 etc. as well as different brands of ram. The motherboard makes the sound upon boot that lets you know it is running. The HDMI cord is plugged into the Graphics card. I have not tried using a VGA cable because I do not have the correct adapter for the slot on my card. I have gone through the check list on Toms hardware and it didn't seem like i was doing anything wrong. I tried resetting the CMOS and didn't see anything.
 
Solution
Most likely your motherboard is toast because you had bent pins before and some were damaged.

PCIe power connector plugged into the graphics card?
ATX12V connector plugged in with 8 pins and not just 4 pins?

reset the BIOS by clrCMOS jumper

just use CPU, cooler, PSU, motherboard and one RAM, use only the power button and disconnect all other frontpanel connections like audio, USB, LED,...

Just tried taking out the GPU and plugging the HDMI into the motherboard and got nothing.
