How to fix faulty intel graphics 5500?

A “faulty” Intel HD Graphics 5500 error usually points to a driver conflict or hardware issue. First, boot into Safe Mode, use DDU (Display Driver Uninstaller) to completely remove Intel graphics drivers, then reboot and install the official OEM driver (from Dell/HP/Lenovo support—not Intel’s generic one). Update BIOS and chipset drivers. Disable Windows Update auto-driver install temporarily. If Windows freezes during install, test with a Linux live USB—if it also glitches, the GPU (CPU iGPU) or RAM may be failing. Run MemTest86 and check system temperatures. Hardware failure requires motherboard/CPU replacement.
