Sometimes when using my computer, especially when I'm just watching videos in a browser or just browsing in general, my computer will soft lock. I'm not able to close the browser, open any other programs, use the start menu or the taskbar. Attempting to shut off the computer through software either does nothing, or attempts to shut down infinitely. I am forced to hold down the power button for the PC to shut down.. I have reimaged the computer 3 times, ran memtest86 with no errors, ran chkdsk with no errors, ran sfc with no errors, and at this point I'm at a loss. My specs are an AMD 5600x sitting in a B550 Tomahawk from MSI, MSI 1660 Super, and 32GB of Trident Z 3200 ram. I would appreciate any help I can receive in fixing this issue and I thank everyone in advance.
