The following explains how to troubleshoot the BSOD error “Attempted Write to Read-Only Memory” caused by a failure in win32kfull.sys.

  1. If you get a Stop code: Attempted Write to Read-Only Memory (Figure 1)

Figure 1

lower the RAM frequency

  1. Boot into the BIOS/UEFI settings. This is done by pressing a key (like Del, F2, F10, or Esc) immediately after powering on.
  2. Navigate to memory or overclocking settings (often called "XMP," "DOCP," "EXPO," or "Memory Frequency").
  3. Disable any XMP/DOCP/EXPO profile. This will make the RAM run at its base JEDEC standard speed (e.g., 2133 or 2400 MHz), which is lower and more stable.
  4. Alternatively, manually select a lower frequency (MHz) than the current setting.
  5. Save changes and exit (usually F10).

Remove one Ram stick

  1. Power down your computer completely. Unplug it from the electrical outlet.
  2. Note the current configuration. If you have two sticks, remember which slots they are in.
  3. Release the retaining clips on both ends of the stick you wish to remove. They will pop outward.
  4. Gently but firmly pull the RAM stick straight out.
  5. Try one RAM stick alone in the recommended primary slot
