Why is my CPU, memory, and disk so high?
When we run programs, they consume some amount of RAM. High CPU, memory, and disk can be caused due to many reasons. Most commonly, heavy graphics games and software consume more CPU, RAM, and disk. Moreover, running multiple programs at the same time also consumes a lot of RAM and shows high CPU usage sometimes. If a lot of apps are running in the background, you may see high CPU, memory, and disk usage in the Task Manager.

In this guide, we have covered a step-by-step procedure to troubleshoot the mentioned issue after studying and implementing methods discussed by others as well as our own experimentation. Many forums mention methods like disabling the Superfetch, Prefetch and the BITS services as well, but we would not recommend the same. I mean what and how much can you really disable to fix an issue!
If you are facing such an issue, here are a few troubleshooting steps that may help you resolve the issue. Create a system restore point first and then go through the entire list and decide which one or more of the suggestions you want to try. Since the reasons can be many, the solutions can be many – so go through the entire list first and see which may apply in your case.
1] Uninstall 3rd-party browsers
Using the Control Panel, uninstall all browsers – except Edge and Internet Explorer of course. This is to isolate the issue with the plugins. The other suggestion is to remove the plugins one by one from each browser and test. Adobe Flash and Shockwave Player are the usual culprits. But knowing the fact that the browsers could be re-installed in seconds, this option seems to be easier. After uninstalling the browsers, please delete the ‘Temp’, ‘%Temp%’ and ‘Prefetch’ files. Restart the system and check if it solves the issue. If it does, wait for 10-15 minutes to verify that it doesn’t reoccur. Then re-install the browsers.

2] Run Chkdsk

5] Disable Print Spooler Service
If this doesn’t fix the issue, Run services.msc and disable the ‘Print Spooler’. Your printer will stop working after this. But at least it helps isolate the issue. Disabling the Print Spooler service has worked for many users. Once the Services Manager is opened, scroll down to ‘Print Spooler’ and click on the option to stop the service. If it works, you could decide if your work actually needs a printer. If you need the service, a technician level repair would be needed.
6] Adjust the Visual Effects
Adjust the Visual Effects in Windows. This post will show you how to tweak Visual Effects to optimize Windows performance.
7] Update Device Drivers
Sometimes Device Drivers can be the culprit. So update your Drivers and see if that helps. You could use Windows Update, download it from the manufacturer’s website or use a free Driver Update software.
8] Run SFC & DISM
Run System File Checker as well as DISM to repair the system image.
9] Run the Performance Troubleshooter
Open an elevated Command Prompt, type the following and hit Enter to run the Performance Troubleshooter. This troubleshooter helps the user adjust settings to improve operating system speed and performance. Here are more suggestions that can help you troubleshoot Performance issues.
10] Upgrade your firmware or upgrade your RAM

11] Use Refresh Windows Tool
Another option you have would be to use the Refresh Windows Tool to reset Windows 10 and see if that finally helps.
12] Examine System Health Report
The Performance Monitor is a good built-in tool that lets you monitor and study how applications you run affect your computer’s performance, both in real-time and by collecting log data for later analysis. It is quite useful in identifying and troubleshooting high resource utilization by processes and in generating a System Health Report of your Windows.
13] Troubleshoot using Process Tamer
Process Tamer is a tiny utility that runs in your system tray and constantly monitors the CPU usage of other processes. When it sees a process overloading your CPU, it reduces the priority of that process temporarily, until its CPU usage returns to a reasonable level. TIP: You can use Windows Boot Performance Diagnostics to detect Windows Boot Performance problems.
14] Is Message Signaled Interrupt enabled?
In a special scenario, if your Task Manager shows 100% disk utilization on Windows 10 devices with Message Signaled Interrupt (MSI) mode enabled, then to solve this install Intel’s Chipset and Management Engine Interface driver and see. This post will help you if you see Random Disk Usage Spikes.
15] Turn off Windows write-cache buffer flushing on the device
Pijal recommends in the comments below. Go to Device Manager > Disk drives. Right-click on your HDD/SSD to shown Properties > Policies. Select “Turn off Windows write-cache buffer flushing on the device” and click OK. See if this helps some of you.
16] Run Power Troubleshooter
