Fortunately, there are multiple solutions available that address both hardware and software-based causes. Understanding when the issue started and what changes were made to the system can help narrow down the right fix. In this guide, we’ll explore all the proven methods to correct the INVALID_AFFINITY_SET BSoD error in Windows 11/10.

REFERENCE_BY_POINTER is a Blue Screen of Death (BSoD) error that occurs in Windows 11 and 10 when critical system processes or drivers encounter severe issues. This error is typically identified by the stop code 0x00000018 and signifies that a reference count for an object is invalid or corrupted. In simpler terms, it means Windows attempted to remove a memory object still in use or referenced improperly. Common causes include outdated or corrupt drivers, faulty hardware components, or software conflicts, especially after recent updates or installations. Sometimes, malware infections or corrupted system files can also trigger this error. Users might experience sudden system crashes, reboots, or freezing screens when this BSoD occurs. It is crucial not to ignore such errors, as they may indicate deeper system integrity issues. If left unresolved, the error can lead to data loss or system instability. Thankfully, there are several proven troubleshooting methods to fix it. These range from basic scans to advanced driver and system file repairs. Understanding the root cause is key to applying the right solution and restoring system health.

CRITICAL_STRUCTURE_CORRUPTION is a Blue Screen of Death (BSoD) error in Windows 11/10 that indicates a serious problem with your system’s kernel or hardware. This error usually points to critical system files being modified unexpectedly or hardware components failing. It can be caused by faulty drivers, memory corruption, or even malware interference. Often, the error message appears when the system detects that a kernel mode driver has attempted to modify critical structures. This type of error can crash your system and force it to reboot repeatedly. Users may experience freezes, random restarts, or sudden shutdowns without any warning. One common cause is outdated or incompatible drivers, especially after a major Windows update. Additionally, overclocking software, virtual drive tools, and old antivirus programs can trigger the issue. In some cases, corrupt system files or disk errors may be responsible. The error may also be linked to failing hardware, such as RAM, hard drives, or power supply units. Because the root cause can vary widely, it’s essential to follow a step-by-step troubleshooting approach to resolve the issue effectively.

ERROR_ACCESS_DISABLED_NO_SAFER_UI_BY_POLICY is a Blue Screen of Death (BSoD) error that typically occurs in Windows 10 and 11 systems when administrative policies restrict access to certain apps or system features. This error is associated with the error code 786 (0x312) and often appears with the message: "Access to %1 has been restricted by your Administrator by policy rule %2". It generally indicates that Windows Defender, Group Policy settings, or other local policies are preventing a user or application from executing specific actions. In most cases, this problem is triggered when an app tries to launch, but system policies block it due to security concerns. It can also occur after a Windows Update or a change in system security settings.
