Issue: How to fix Randgrid.sys BSOD in Windows?
Hello, I have constant BSOD crashes when I'm trying to launch CoD: Modern Warfare II. The referenced file is Randgrid.sys. What can I do to fix this?
Solved Answer
Blue Screen of Death (BSOD) errors, such as the one associated with Randgrid.sys, are critical system errors in Windows that halt the operating system to prevent damage.
These blue screens typically display a stop code that helps in diagnosing the underlying issue causing the system instability. They serve as a protective mechanism, forcing the system to stop all operations and alerting the user to significant problems that require immediate attention.
Randgrid.sys BSOD error typically manifests when launching the Call of Duty game via the Steam or Battle.net platforms. This particular driver file, essential for the game's operation, has been noted for causing stability issues such as system freezes, slowdowns, and crashes that may prevent the game from running properly.
Such disruptions often escalate to a Blue Screen of Death, characterized by specific bug check values, and can frequently initiate a cycle of continuous system restarts.
Several underlying issues might trigger the Randgrid.sys BSOD. These include the driver lacking a proper digital signature, interference from VPN services, corrupt driver files, and updates that introduce system instabilities. Additionally, compromised system integrity due to malware, faulty system files or installation components, and conflicts with third-party software are common culprits.
Below you will find several methods that should help you fix Randgrid.sys Blue Screen crashes so you can continue playing your favorite games. If you would rather take a more hands-off approach, you can always rely on a powerful PC repair application such as FortectMac Washing Machine X9.

Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data.
