[STUTTERING] Computer slows down after a few hours even when idling. Temperatures and hardware seem fine and virus scans show

Basically whenever my computer is on for 2-4 hours it starts to stutter. What I mean by that is my mouse starts moving REALLY slowly and if any audio is playing, it becomes slow and static sounding.

I've run a CHKDSK with no issues. I've run Advanced SystemCare, BitDefender, and MalwareBytes with no issues.

The problem persists whether I'm browsing/gaming or letting the computer sit idling while I'm away. I would like to figure out if this is an actual problem that can be fixed or I may need to reformat my system, assuming it actually is software and not hardware.

Any insight into this issue is welcome!

Here is my HWiNFO while my computer is freshly restarted, does it seem abnormal?: http://i.imgur.com/R9Zleqv.png

I looked it over and I THINK it's fine? I'll post another picture in a few hours once my computer has been turned on for a while to compare.

Hey there, Bob!

I'd recommend you check the connections to the SSD & HDDs inside your rig, you might also want to reseat them. Unfortunately, CHKDSK is not working for solid-state drives. As for the HDDs, you should consider using the brand-specific utilities to check their health and SMART status. Using the manufacturer's diagnostic tool is a good way to accurately monitor your drives' performance. You should be able to find the software on their official website.
I'd also check if you have the latest firmware update for the SSD and use one of these testing tools to check its SMART data and health as well.

If you proceed with the reformatting of the system and clean installing Windows, make sure you unplug the secondary drives from the SATA Ports, otherwise, you might encounter an OS confusion.
You should also backup all your essential data elsewhere beforehand, in order to avoid any potential data loss.

Hope this helps. Keep me posted. :)

Have you updated your gpu drivers lately? if so try installing older drivers. otherwise clean windows install is the best way to see if it's a hardware or software problem. if it's hardware, id say it's either your ram or mobo. you can test ram with memtest86 and by running your pc with 1 ram stick at a time.

Thanks for the reply! I have checked the health of my SSD and HDDs and they are running perfectly fine. I have also checked my drivers and tested my ram with memtest86 and it's all good. I'm thinking maybe a BIOS setting got screwed up somewhere? Here is the new HWiNFO after my computer being online for 9 hours: http://i.imgur.com/PULcQkf.png

Also here is this really odd thing that is happening to my CPU... https://www.dropbox.com/s/gnxwfsm03u1t61s/2016-04-06_15-37-11.mp4?dl=0

Pay in mind that my CPU is supposed to max out at 3600 Mhz so I have no idea why it's halving itself while also randomly shooting up to 3700 or 3800 Mhz.

The stuttering only happens whenever I open a program, do something with a program, load/reload a webpage, etc. Once the task is finished, the stuttering stops but resumes again once I start another task.
 


Try running it with just the essentials needed to work (no gpu, unplug all unnecessary drives and usb devices, boot windows in safe mode) and see if it still happens,
if it does it's most likely your mobo that's broken.
 
Hello again, Bob!

I'd suggest you troubleshoot your whole system, indeed. Unfortunately, these stutters could be caused by a lot of things. Here's a tutorial from the community you might find useful.
If you feel uncertain about doing this yourself, I'd suggest you save yourself the headaches and go to the nearest PC repair service store. The guys there should perform full diagnostics on your PC and, hopefully, find the source of the issue.

Good luck! Hope this helps. :)

The difficulty of troubleshooting my system by doing what you guys are suggesting is that the stuttering doesn't happen until after my computer has been online for several hours, so troubleshooting would literally take days. I'll keep you guys updated on what I try. Thanks!

I've resorted to reformatting my computer and it seems the stuttering has been fixed. I have no idea if it was a program or virus or incorrect settings that was causing it but for now, it seems to have subsided. Thanks everyone for the answers!
