Why is my Windows 11 PC stuttering?

What happens if you purchase a new SSD, and install Windows on it?

Does the replacement SSD work much faster than the replaced SSD?

Software like "Crystal Disk Info" and "SPECCY" can report on the "health" of the SSD.

Hi, thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today, my timezone is UTC +8.

I understand the issue you have, there is nothing to worry I am here to help, have you noticed any changes before the issue started? For example, have you installed any new hardware or software that might have triggered the issue? while waiting for your response, can you please check the System logs on the PC so that I can further examine the root cause of the issue?

To do this kindly follow the steps from this link:

Hi Benjamin, I’m Eric, and I’d be happy to help!

Since you’ve already narrowed the stuttering down to SSD usage, it’s possible that your SSD is experiencing high read/write latency, degraded performance, or failing sectors. First, check its health status using a tool like CrystalDiskInfo (free download) to see if there are any warning signs like high reallocated sectors, pending sectors, or bad blocks. If your SSD is struggling, enabling TRIM can help—open Command Prompt (Admin) and run:

fsutil behavior query DisableDeleteNotify

If it returns 0, TRIM is enabled; if it returns 1, enable it with:

fsutil behavior set DisableDeleteNotify 0

Another possibility is that your SSD firmware is outdated or the SATA controller is running in the wrong mode (like IDE instead of AHCI). Check your motherboard’s BIOS settings and ensure AHCI mode is enabled for the SSD. If you haven’t already, try swapping the SATA cable or port, as a faulty connection can cause intermittent stutters.

If the stuttering persists, I’d also recommend checking Event Viewer logs (as Bernard suggested) to see if there are recurring disk I/O errors. Let me know if you need help running those checks! If this helps, please mark this reply as helpful or as the answer.

Best,

Eric
