Update Graphics and Monitor Drivers
Outdated or unsupported graphics configurations can cause rendering crashes during intensive search operations across multiple monitors.
A system configuration with multiple monitors of varying resolutions can strain unsupported graphics cards. Updating the display drivers ensures proper rendering compatibility when the PDF reader highlights search terms.
Right-click the Start button in Windows 10 and select 'Device Manager' from the context menu.
Expand the 'Display adapters' and 'Monitors' sections to find your specific graphics card and connected monitors.
Right-click your graphics card and select 'Update driver'. Choose 'Search automatically for updated driver software' and follow the on-screen instructions.

Verify System Memory and Page File Settings
Low physical memory (RAM) or an improper virtual memory configuration can trigger application closures during heavy searches.
Uninstall and Reinstall Adobe Acrobat Reader DC

Frequently Asked Questions
What is Fast Find in Adobe Acrobat?
Fast Find is a search optimization feature that creates an index of the PDF document to speed up text queries. However, it can consume significant system resources and cause crashes on systems with limited memory or unsupported graphics cards.
Why does a multiple monitor setup affect PDF text searches?
Using multiple monitors, especially with different display resolutions, can strain the graphics driver when rendering search highlights. If the graphics configuration is unsupported or outdated, the rendering process may fail, leading to an immediate application crash.
Is it safe to delete the Windows page file to free up memory?
No, deleting the Windows page file is highly discouraged. The operating system actively uses the page file as virtual memory to manage background tasks efficiently. Removing it can cause severe system instability and trigger more frequent software crashes.
How do I temporarily disable Fast Find in Acrobat?
You can modify your search preferences by opening Adobe Acrobat, navigating to Edit > Preferences, and selecting the 'Search' category. From there, you can purge the cache contents or disable fast find indexing options to prevent crashes.
