I made a huge mistake when putting in my new CPU, I put it in the right way but I had to reposition it because it didn't go down and I was under pressure since it was a 4790K because I didn't want to do anything wrong. After that I applied thermal paste and spread it and it had managed to get stuck on the card I was spreading it with putting it out of place again and then realising I had forgotten to clamp it down with the CPU housing. Everything booted up fine and I had no crashes or anything.
