PC Laggy after upgrade

check your minimum processor speed in classic control panel\ power. I had this and nearly wiped my pc then noticed min cpu was set to 5%, set it to 50% and everything's fine again.
 
Some sites give a lot of lag with me with chrome but the same sites on firefox do not, ive had the same page in Chrome use up 80% of my CPU but on firefox under 5%, if you get slow downs again check CPU usage whilst you are on the tab for the game you are playing.
Yea i have recently started using Firefox over chrome for this reason, chrome has like 15 instances open for 1 tab, its crazy
 
I found my PC (same processor as you) is laggy and not that snappy any more, since I upgraded from Windows 10 Pro to Windows 11 Pro.
ive been thinknig abou going back to windows 10, I was on windows 11 before the upgrade tho and it worked fine :( ive noticed now i get a crackling sound in my speaker followed by 1/2 secs of lag and then the computer starts to run sluggish.

i run latenacymon and it shows a sound card driver or files as the issue but i can not for the life of me get rid of that error :(

It's stupid things with Windows 11, like my label machine. If I don't remember to turn it on BEFORE I boot up my PC, printer software doesn't see the printer and I have to reboot the PC with the label printer already on, before I can print labels. Never had that probelm with windows 10.

Bluetooth speakers, windows 10 no problem moving from the speak to headphones, when I turned the speaker off. With Windows 11, I have to manually go into the sound settings and pick the right source.....windows is just a ballache :/
 
I'm a little unclear weather this has actually been solved or not, so I'm going to go on the basis of not. I did not see you mention removing the additional memory modules that you installed, I would do this if I were you and run without for a while and test, make sure you get the ones you put in last not the original ones if you can tell the difference aswell, because large numbers of page fault errors do suggest either a memory or a disk issue, given that you have not changed the disks but you have added memory I would work from there to start with. If it seems ok I would then run Memtest86 both with and without the new memory modules in and see what that shows.

While it might be a fun pile-on to point fingers at Windows 11, I doubt that is the issue here, having said that, do check the updates and see if any were applied at the time you did the upgrade, albeit a rather outside chance, it's possible the last time you shut it down before the upgrade it had one pending and then it finished installing it as you booted it up with the hardware changes, as I say, unlikely as you would have most likely noticed, but possible. Even if it did, I still think the issue is more likely to be the memory or a disk given the page faults you mentioned.
