My pc is lagging (please help)

[byokayt]

Hi!

two months ago, i builded my own gaming pc, it was working perfectly fine until 4 days ago, when i did a cleanup. I used it right after cleaning it and it was perfectly fine, it was only the next day that i had some really weird lags and freezes. While my pc was running Call of Duty Warzone and Apex legends at 120 fps easily, now it goes between 55 and 70 and it has A LOT of freezes while playing. First, i checked if i didn't broke any component, everything looked fine, i replaced my RAM to be sure it wasn't badly plugged, it was fine, i checked if my cpu cooler was badly putted on my CPU, it was alright, i even changed my thermal paste just ot be sure and it didn't changed anything. After checking in my pc, i tried to check if there was any thermal issue so i opened speedfan and runned apex legend, the cpu was totally fine, the graphics card was at a normal temperature (between 50 and 60 degrees) and none of my fans were running faster than before. After this, i opened my antivirus (Malwarebyte) and i did a full scan, no virus at all, my pc was clean. Then, i decided to double-check if it was my ram so i did a full scan of my RAM  the diagnostic was: no problem were detected. After this, i changed my GPU driver to the last update, right before the one i was using before. Finally, in a burst of despair, i decided to reboot my whole Windows 10, as i expected, it chnaged nothing except the fact i had to re-install all my games and programs. 

 

If you have any clue of what is happening to my pc, i would be really gratefull if anyone could help me.

Thank you...

Just going to throw a few suggestion at you.

First, try to  remember everything you did during your cleanup. You don't really say if you only cleaned your PC physically, or if you cleaned up your Windows as well.

For example, if you used DDU, it could happen that some driver(s) get partially removed, that shouldn't be removed. Pretty sure that happened to me once. 

 

Also, disable or unistall Malwarebytes, Windows Defender is pretty good by itself already, and you  risk complications when having multiple antiviruses active. 

When you have removed Malwarebytes, make sure that Windows Defender makes an exception for your games, for example in the firewall options.

Also check task manager for any suspiciously high usage during gaming.

Also, have only your necessary programs running in the background and on autostart (disable unnecessary programs in Task Manager) and restart your PC before gaming. 

If you have a Gsync-Monitor, disable Gsync.

Also, make sure in the Nvidia control panel that your PC is using the Nvidia Graphics card, not your integrated CPU-Card, and check for any weird V-Sync settings in games and Nvidia control panel.

If it was only a physical issue, check if everything is plugged in correctly, not just your RAM. If nothing helps, disassemble and reassemble your PC again. 

 

 

Maybe collect some more details about the whole thing, and try to remember everything that you changed or added.

I was checking my task manager and i saw this... is it normal that the memory is used between 35% and 40% while there's only windows defender and the task manager running ?

On your point about graphics card it would use the CPU's as he states he has a 9400f which don't come with graphics. I'm not being a smartass or anything
