So I recently bought an intel i7 9700k to upgrade from my intel i5 4460. I also purchased a cooler master hyper 212 evo since I was using a stock cooler before. After upgrading (kind of sloppily since it was my first time upgrading a cpu) the computer turned on for a split second then turned back off. I showered the internet the tried some solutions but eventually just reseated the cpu and tried again. This time, the computer turned on but my monitor received no signal. After trying nearly everything (using motherboard hdmi socket, resetting cmos although I didn’t take the battery out because it didn’t seem like it wanted to come out) I had no luck. I tried numerous solutions while swapping between the new processor and the old processor to try to figure it out. Eventually, I came across a new issue where the power button did nothing at all when I had the i7 in. I swapped back to the i5 and even to the stock cooler, and I came across the same issue where the computer turned on with no signal. I am using a Fatal1ty killer Z97 motherboard. My question is 1. How can I fix the turn on but no signal issue and 2. Although I fear the i7 might have been killed in my struggles, is this actually the case and can I fix it somehow? Also I did check the motherboard socket pins and they all seemed unbent
