Tired of Windows freezing? Try these fixes to stop it for good

Is your PC working fine at one moment and suddenly becoming unresponsive the next? It’s incredibly frustrating and, worse, there’s rarely a single clear cause. The slowdown could be caused by software issues, faulty drivers, overheating, or a combination of several factors. Here are the fixes you can try.

Stop apps from consuming your resources

The most common cause of system crash is that the computer is running low on resources, especially RAM or CPU. This often happens when a browser has too many tabs open, game launchers are running in the background, cloud saving is synced, or other heavy tasks are taxing your computer’s hardware.

So, your first step should be to confirm if resource usage is at issue and, if so, release those resources. Right-click the Start button and open “Task Manager”. Go to the “Processes” tab, sort the list by CPU, memory or disk usage to see which processes are using the most resources. Spot applications or processes using excessive resources and disable them.

To stop a task, right-click it and select “End Task”. Reduce this load to give Windows enough breathing room to avoid random crashes.

Stop your computer from overheating

Overheating is another hidden culprit of Windows randomly freezing. When your PC gets too hot and temperatures exceed a certain limit, the system automatically limits performance to prevent hardware damage. This slowdown often manifests itself in blockages. So you need to check if heat is the problem, either by feeling the temperature of the machine or using an app.

I use HWMonitor to track temperatures in real time. If you notice components consistently operating above 85°C, it’s time to take action. Clean air vents to remove dust and improve air circulation, and avoid placing your device on soft surfaces like beds or blankets. You can also use a cooling pad and reduce heavy workloads to help keep temperatures under control.

Update or rollback your graphics drivers

A corrupted or outdated graphics driver can also cause your PC to crash. Therefore, you need to update it to the latest version to fix the issue. Conversely, if a freeze, stutter, or hang starts right after installing a new driver update, the update itself may be faulty. Canceling it can therefore solve the problem. So make sure to rule out any driver-related issues.

First, download the appropriate driver from your GPU or laptop manufacturer’s website. To install it, right-click the Start button and open “Device Manager”. Expand “Graphics Cards,” right-click your GPU and select “Update Driver.” Select “Browse my computer for drivers” to select and install the downloaded file, or choose the automatic option to have Windows search for one.

If you suspect that a recent driver update is causing the problem, right-click the same driver, open “Properties”, go to the “Driver” tab and click “Roll back driver” to revert to the previous version.

Find and Fix RAM Problems

If your computer freezes even during light tasks (and Task Manager shows that your RAM usage is approaching 100%), a memory problem could be the cause. This is a rare cause and easy to overlook, so it’s worth checking out. Press Win+R, type mdsched.exeand press Enter. Then select “Restart now and check for problems”.

Your system will reboot and run the Windows Memory Diagnostic tool to check for RAM errors. If it finds something, you may be dealing with a faulty RAM stick, improper placement, or another problem. Shut down your PC, firmly reseat each RAM module, or test the system one key at a time to identify which one is faulty. You can also use Event Viewer to check for any problems with registered software.

Keep Windows fully up to date

If you usually keep Windows updates paused, an outdated operating system may be the cause of sudden crashes. Microsoft frequently deploys patches that fix bugs, improve stability, and improve hardware compatibility. So, if you have fallen behind on updates, installing them may resolve the unexplained crash.

Right-click the Start button and open “Settings”. Go to “Windows Update” and resume any suspended updates. Even if nothing is paused, click “Check for Updates” to check for new patches, then select “Download and Install.” Also make sure to install optional updates. Once fully updated, many freezing issues resolve themselves.

Disable hardware-accelerated GPU scheduling

Hardware-accelerated GPU scheduling can increase performance and improve FPS by allowing your GPU to manage its own memory. However, on low-end systems or in case of compatibility issues, enabling it may cause stuttering or freezing in some applications. If you recently enabled it and started noticing crashes, it’s best to disable it.

To do this, right-click the Start button and open “Settings”. Next, go to System > Display > Graphics. Here, expand the “Advanced graphics settings” menu and turn off the “Hardware-accelerated GPU scheduling” toggle.

After that, restart your computer for the change to take effect and check if the problem is resolved.

The fixes above should help identify the cause of the freeze and resolve this issue. If the problem persists, run SFC and DISM scans to detect and repair corrupted system files. If the problem persists, check your storage drive for crashes, update your BIOS to the latest version, disable Fast Startup, and try creating a new user profile to see if these steps resolve the issue.
