Computer recently became slower

January 26, 2019 at 02:32:07
Specs: Windows 10, i5 6600k 4.2GHz / 8 gigs
Recently my computer has slowed down. I can no longer run games at 60 fps that i previously could and most programs such as my browser (firefox) have lag too as well as occasional temporary freezes.

Additionally when launching battleye my PC crashes usually without a bsod , i have had 2 Blue screens however only one stuck around long enough to read. This specific issue started after a windows update where the symptoms appeared for most programs a few minutes after launch.

I have re-installed windows/drivers, as far as i can tell no hardware is at fault. After re-installing the chipset drivers the symptoms were alleviated however they came back when windows defender hogging my CPU but that issue is fixed.

All in all, no clue whats going on.

While Microsoft seems to like to occasionally use us as beta testers for their faulty updates, it doesn't happen that often.

I've had this problem in the past and it was caused by other background programs. When I had McAfee
it was often a problem. I now run the Windows Defender AV (greatly improved over earlier versions, and free). No AV problems and it plays nice with MalwareBytes (McAfee didn't).

See what else is using high CPU with Task Manager and if it doesn't look important, disable it (don't delete just yet) with CCleaner. Then run the usual malware programs. Make sure you only have one AV running (Defender, Norton, McAfee, etc. can and will fight each other and cause slow-downs and lock-ups).

I don't have multiple AVs installed and there are only 2-3 processes that use a noticeable amount of resources aside from programs I'm actively using. They're taking up at most 15% of my CPU and aren't things i can just disable.Ive scanned my system before but just did it again and no problems have popped up.

I would have spent more time troubleshooting rather than going to the extreme of replacing the OS. Assuming you did it correctly (deleted existing partitions & then repartitioned the drive), the reinstall should have removed any infections that may have been affecting performance. However, we have no idea what else you installed. Hopefully when you installed the drivers, you installed them manually rather than using one of those "driver finder" programs. Most of them are snake-oil & do more harm than good. The 1st driver to be installed should have been the chipset driver, after that, the order doesn't really matter.

Other programs you installed could be causing performance issues. How are you monitoring your startup apps? Many of them are completely unnecessary & have a negative effect. Do you have CCleaner-Slim installed? If not, get it here: https://www.ccleaner.com/ccleaner/b...
You can then click on Tools > Startup to see the list of programs that load at startup. You can either disable or delete entries.

High CPU temp can negatively affect performance too. If the CPU gets too hot, it will begin to throttle (underclock) to try to lower the temp.

Yeah, i shouldn't have re-installed the os when i did.

Does the order of driver installation matter? i installed the gpu and cpu drivers before the chipset drivers.

Ive been using task manager to check my startup programs. Should i look in the "scheduled tasks" and "context menu" sections for troublesome programs?

My temps are all fine.

If you did not delete all partitions and create new ones before installing your operating system then Root Kits (root infections) could have survived and still need to be removed. You can run Malwarebytes to do this as long as you make sure that the 'scan for root kits' is checked in settings, then second tab on the top.
I prefer to then go to the My Account tab and click the End Free Trial to make it 100% free version.

You have to be a little bit crazy to keep you from going insane.

slow computer are programs running in the background. Remove or disable any TSRs and startup programs that automatically start each time the computer boots. Additionally, please try these steps and see if they help: https://dailytechposts.com/computer...

crashes and slowdown under heavy load?? random shutdown without warning??

what about thermal shutdown, get something like RealTemp.exe and check the temps during load, see if they hit 90+ C

P.S. why aint you running your i5 6600k@4.5 GHz@1.25vcore + 4.2GHz cache? :D

The only crashes have been when launching battleye.

My temps are all under control and the freezing doesn't seem to correspond to stress.

It looks to me like it lags whenever its loading anything.

it could be windows anti-malware executable, had some issues with that on my laptop before.
hogging up 50% cpu when loading apps.

you could try disabling windows defender and go on from there
