Windows 8 computer suddenly became slow, 100% disk usage

My Task Manager:
taskmgr.png

HP Pavilion with Intel Core i3 running on Windows 8 and NVIDIA GEFORE GT 630M 1GB

---

My relatively new (about 2 months old) laptop running on Windows 8 suddenly became slow. I noticed it starting yesterday when it became really laggy. Just a few days ago it was working just fine.


I tried to look for solutions online and was worried that it might be caused by malware. I did a quick scan with Malwarebytes and it found no infections.


When I boot in safe mode, it seems pretty fine. I tried doing a system restore but I was also informed that it wasn't completely done probably because of an antivirus.


My antivirus is Norton Internet Security and I've read that Norton can be such a hog so I've tried disabling it though not entirely and it hasn't been uninstalled yet. What worries me is that I haven't experienced this problem even with Norton running until just recently.


I've also tried running a chkdsk /r because going to Tools > Check for Errors on my C:\ drive said that there were errors that needed repair.


It has become less laggy but apparently not totally (not to previous state). My task manager however still shows 100% disk usage. Previously Norton would be listed among the top but now it's usually "System" and I don't quite understand why.


Help very much appreciated! Thanks. :)

It might be Windows trying to index the contents of your hard drive which is worth shutting off to test.

Open your start menu and type "indexing options" and choose the first entry in the Settings category. Remove everything from the list and restart. Does it have any effect?

Anyways, I decided to do a refresh and it works fine now. I still don't fully understand what happened. Probably it was an installation but I can't be certain. Thanks for the help! :)

It will happen periodically. System background maintenance takes over the system for several minutes with a lot of memory, CPU and Disk activity, and normal work becomes difficult during these busy periods - annoying, but they pass, and everything goes back to normal.

Task manager shows

Service Host: Local System (7)

(or something similar) doing most of the usage, and applications are slow to start, or fail to respond for a while.

I remember XP doing something similar during its early days, then one of the updates fixed it.

Hi there
With Windows 8 you don't really need any external / 3rd party AV software - these often cause excessive disk usages and often can't be seen in Disk usage monitors.

I notice you have Symantec -- that usually is enough to raise at least a "Yellow card". -- Try uninstalling ALL A/V software and just rely on the standard built in Windows AV software (Windows defender). It's actually very good.

If you are a bit worried about doing this just keep disconnected from the Internet at the time you are doing your test.

Cheers

I agree. Windows Defender (formerly Windows Security Essentials if you're still a Windows 7 user) is great and I generally recommend it over any 3rd party A/V.

I had the same problem which occurred immediately after upgrading from 8 to 8.1. I spent a lot of time following suggestions but what rescued me was coming across a post, which at first I thought was a company promotion, saying that CCLEANER would solve the problem with their registry clean-up tool. And it's free. I downloaded the software and ran the registry cleaner three times (rebooting each time) and problem solved. My disk usage is running along at 5-10% and no more time wasted. I was just about to the point of buying a new computer but have to thank this company for saving me the time and money. QUICK, EASY & FREE

Please DO NOT use the built in windows Anti-Virus as it literally does not do anything but stop .EXE files from running. It is NOT a real antivirus

No I am not from Apple. Most of the total PC users on the planet would agree with me. It has been tested and proven to be terrible. I did a scan with it before. And then I scanned again just to be sure. It didn't pick up anything. I put a REAL antivirus onto it and the real antivirus picks up 6 straight away

Microsoft Security Essentials does exactly what it is made to do.. "Re-actively stops .exe and other files from doing things on your computer and registry"

it doesn't "Proactively" find viruses which is probably why you say its terrible.. other 3rd-party anti-virus programs do this.

I agree that you must use other apps to search for things but Microsoft Security Essentials atleast prevents registry and standard virus procedures.. It also removes viruses pretty well. I've been to far too many "untrusted" sites and have not been ever hijacked or had a virus. But I also know what I'm clicking.

I'll give you the other programs I like are ESET online scanner and Hitman Pro and Malewarebytes.

But whlie microsoft definitely has its shortcomings, i would hope that they know what processes and behind the scenes files to be checking/look at to see viruses etc..

To handle with this kind of problem, first go to Disk Clean up by right click and run as administrator. Now check your system properly and clean all junk from it using some good cleaning software. Then defrag your hard drive and run safe boot. Hope this helps.

I've been strangely getting this problem over the last week. My HDD is showing 100% usage and my PC runs at a painstakingly slow pace that I almost feel like throwing it out of the window!

I've tried disabling windows search, defrag, auto maintenance and even full scans but nothing.

The problem will go away for 5 minutes and then start again. It's driving me insane!

On Windows 8 or Windows 10. If Norton 360 or Norton Security suddenly goes to 100% disc usage every thirty days, it is because by default an automatic full system scan is taking place. After a year of talking to Norton support I finally figured this out myself. On Norton Security, go to Settings / Antivirus / Scans and Risks / Full System Scans / Configure /Edit Scan / and click do not run this scan.

Hi,

Glad you've fixed. Let us know if you need more help on Norton.
Thanks in advance!
