Borked motherboard by changing CPU!
Discussion
Afternoon all.
Bit of a weird one this as I've built at least 40 computers over the years and never had an issue like this!
I've got (well had!) and MSI B450 mini itx board with Ryzen 2600 installed. I decided last week to treat it to a 5800x. Installed it and posted but didn't load. Realised it was in need of a bios update. put 2600 back in, flashed bios, rebooted into windows all good.
Yesterday morning I decide to swap back over to the 5800x. Simple enough, unplug everything, remove cooler, lift out old cpu, install new cpu, put cooler back on. easy peasy.
Go to plug everything back in and upon plugging in my port replicator (powered but only used for easy usb access) which was running fine before, the speakers let out a buzzing moo noise which fades away. Try turning it on. nothing. No motherboard l ight or post or any sign of life.
Fast forward to today and I've fully stripped down the pc, held in power button to let any current discharge, remove cmos battery (well unplug it as it's glued onto the back of the IO ports!) wait 10 minutes. rebuild. Nothing. Tried both new and old cpu too.
I've tried bridging my PSU and that's working fine.
Could I really have borked my motherboard by doing really not a lot? Literally the only thing I can think of is plugging the port replicator into a USB 3.2 port in the back rather than the USB 2.0 it was plugged into before?
I've ordered a new mobo for delivery tomorrow but I'm still hopeful I can revive this one as I don't wnat the faff of having to try and reactivate my windows and office!

Did you remember to earth yourself against the case (or anything else) before messing around the any of the components? Could easily be a knackered board.
Never worn a grounding strip or purposely tried to ground before, perhaps I've just been incredibly lucky until now?jimothyc said:
Does your motherboard support that new CPU? Perhaps its power requirements have exceeded what the mobo can provide and it’s blown something? Or maybe you shorted something when you put it back in the case? A stray screw or standoff can do it.
Thanks for your comments. BIOS update gave support to new CPU and power requirements were okay too. Literally unscrewed nothing other than cooler as I've a small itx case that's easy to get access to everything! Only other thought is the mounting bracket for the cooler was lose under the motherboard and may have scratched/damaged part of the underside of the motherboard but again quite unlikely. Nothing looks scratched, bent or out of place and no "whoops I've burnt something" smells!jimothyc said:
Yep sounds very much like it's an ex-motherboard. Hopefully the new one works out for you.
Almost certainly! If I'd known that was going to happen I'd have bought AM5 cpu and board and been done with it! Ho hum.Just hope I'm lucky in getting away without having to reinstall OS and office and activating them.
Still can't think what I did to bork it. Perhaps after 5 years it just decided it was enough!
I would check you haven't accidentally bent any of the CPU socket pins on the motherboard if you haven't already.
Ryzen CPUs are pretty easy to accidentally move when they are "secured" in the socket. Last time I changed my CPU cooler I accidentally pulled my 5950X clean out of the motherboard socket when I removed the old cooler (I made a mental note to twist the cooler before pulling it out next time!).

Good to know, but thankfully the cooler popped off the cpu quite easily. I've looked at both CPU's and netiher have any bent pins (thankfully!)Ryzen CPUs are pretty easy to accidentally move when they are "secured" in the socket.

I guess it'll be a mystery as to why the motherboard went bye bye!
So just to bring this to a close. New motherboard arrived this morning, built it up and it came to life. Small fTPM error which I simply clicked Y to and in about 2 minutes it booted into windows. Had to reauthenticate office and windows which it did automatically online and I'm now back up and running, no new OS install or anything #lucky!
So, it was a fried motherboard, whatever the reason was. I'm going with old age (6 years old) rather than anything I did wrong!
Thanks to everyone for the pointers.

Happy days, did you have to perform the same bios update? Bet you won't be in a hurry to CPU swap again! 
Completely different brand (ASRock - previous was MSI) and much newer motherboard with native support for the CPU so no need to do bios update.First (and most definitely last!) time I upgrade a CPU and not upgrade motherboard at the same time as they learly don't like it!
