Visit websites of your hardware vendors. Download the latest drivers and related software for your exact PC model for current OS and install them. Pay attention to what you are downloading. Do not forget that the same PC or laptop model can have a variety of modifications with different hardware! If your currently installed OS is not mentioned in the list of supported OS, try to update drivers from Microsoft update server. But keep in mind that drivers installed by Windows 10 itself are not always suitable for your current hardware. That’s why you should install drivers from the official website if they are available.

Make sure there is enough diskspace on your system drive

Windows 10 can randomly freeze, glitch or just slow down because of a lack of a free disk space on the system drive. All those new versions of programs, all those Windows updates and browser caches take so much disk space. So you need to have at least 20 GB of free space to be sure your PC will boot successfully the next time:

So if you have run out of space:

  1. Clean your disk using CCleaner. This will delete browser caches and OS temporary, junk and obsolete files.
  2. Move large files from your disk C to another drive (if you have such).
  3. If you still have very little space on your system disk, resize your partition by taking space from another one or add another drive, etc.

Test your RAM modules

Though RAM errors often result in BSOD or spontaneous reboots, we nevertheless recommend to test RAM modules using Memtest+ utility. Wait until it makes 20-30 pass loops in the utility because not all errors can be diagnosed in 1 pass.
