My Lenovo Ideapad running Windows 10 randomly freezes for 5-10min, then after the freeze, most of my installed fonts are gone (clicking a font in font folder throws an error), and my Explorer (as well as most other programs or context menus) end up with no text. Also, hovering over text in desktop would turn the text blurry.
During the freeze, task manager would register 100% disk usage but 0kbps r/w speed.
Sometimes, after a while (like half an hour), the problem would fix itself and I would see text in Explorer and context menus/windows again. However, the fonts themselves are still missing both in the fonts folder, as well as in apps like Word (I'd only get like 3-4 fonts in the font dropdown).
Missing fonts in font folder:
Blurry text on desktop:
Missing text in Explorer:
Missing fonts in Word:
- Restart laptop. This fixes the issue but if the computer freezes again, issue is guaranteed to be back
- SFC /scannow - no errors
- Updating drivers - graphics drivers are all up to date including Intel HD/Nvidia according to Intel diagnostics tool and Nvidia website. Not sure if there are other drivers I should check
- No viruses according to Windows Defender. Don't have any other antivirus installed, such as the "Comodo antivirus" mentioned by some other users
- CPU/HD temperatures appear to be normal according to SpeedFan app before/during/after the freezes
This only started happening after Creators Update, though I'm not sure if there's any direct correlation.
Does anyone have an idea what might be causing this?
