Disk usage on Windows 10 reaches 100% causing the computer to freeze
I've been using this 1TB solid-state drive for about a year, and recently, whenever I boot up my computer, download a game, or try to take a screenshot, the disk usage spikes to 100%.
Sometimes, while playing games or watching videos, it even causes the entire screen to freeze. I've tried all the common solutions and checked the drive's health, and everything appears to be normal.

Try disabling MSI mode for your Advanced Host Controller Interface (AHCI) used by StorACHI.sys driver.
Let me know if you need further help with this!
The important clue is that an SSD-health check can be normal while Windows still reports 100% active time and freezes. That percentage describes how busy the storage path is, not only whether the drive has failed. Press Ctrl+Shift+Esc, select the Processes tab, and sort by Disk while the problem occurs; then use the Performance tab to see whether the busy disk is the system drive. Note the process name, transfer rate, and available free space. Windows Update, antivirus scanning, indexing, a game launcher, or a storage-driver issue can create bursts, but repeated freezes need evidence. Install pending Windows updates and current chipset, storage-controller, and SSD firmware from the PC or drive maker. Disconnect optional external storage and retry. If a single process consistently drives the activity, troubleshoot that application; if System dominates, save the event details and test with a clean boot before disabling services randomly.
