Hi guys,

I've been having a lot of issues with my PC and eventually came to the conclusion that the CPU was overheating. I was advised to replace the fan/heatsink as it was old/noisey/not working properly. The one in before was just the stock one it came with and was several years old.

I've just done this and the PC powers up fine, all fans work etc. but there is no display on the monitor. I googled this and found similar questions in the forum but didn't quite understand many of the answers given. I'm not particularly savvy at this, definitely feel out of my depth and am scared of breaking everything, but have been following online tutorials for everything so far.

Out of the other answers people gave:
1. I probably did use too much thermal paste, but would rather not touch it again if there are other things to try.
2. Not sure how to go about resetting CMOS/BIOS and couldn't find the bits people seemed to indicate on my motherboard. I'm also not sure if this is necessary since I haven't actually changed the CPU - I just unplugged it in the process of removing my old heatsink.
3. In terms of the CPU being plugged in properly, I think it is. I made sure to replace it in the same orientation it came out and in doing so there was zero resistance. Again, I would rather not pull the whole thing out again if I don't have to.

Any suggestions on where to go from here would be great.

CPU: AMD FX8320
Fan/Heatsink: CoolerMaster Hyper 212x
Motherboard: Gigabyte 970A DS3P - it has a AM3+ CPU port.
GPU: Nvidia GTX 970

Let me know if you need any other specs.

Thanks in advance!

Just an update for anyone else having this issue - After giving up on internet wisdom, I ended up taking the PC to a local repair shop. They found that the issue was in fact not that I had busted my CPU (as I feared) but I had actually just damaged the port on the motherboard that it plugs into. They repaired this for me on the spot and now PC is working with seemingly no issues.

Worth getting it checked out by professionals if you're stumped/out of your depth!

Should probably just take out the cpu and check to make sure you seated it correctly again I know it feels like a pain to do since you hear the metal clanks and stressing it with your fingers but its usually the first thing you should check again if the pc was working and then "poof"! nothing.
