Windows 7 Windows automatically shutting down at login screen

Potential Causes and Troubleshooting Steps:​

1. Compatibility Issues:
   • Ensure that all your hardware components are compatible with Windows 7 x84 and with each other. Check for any known compatibility issues with the specific components and Windows 7.
   []Driver Conflicts:
   • Update all your drivers to the latest versions, especially the graphics card driver. Sometimes driver conflicts can cause unexpected behavior like automatic shutdowns.
   []Windows Update Issues:
   • Try installing Windows updates one at a time to identify if a specific update is causing the issue. You can also try disabling automatic updates temporarily to see if that makes a difference.
   []BIOS Settings:
   • Since you mentioned that resetting BIOS settings to factory defaults is necessary for Windows installation, check if any specific BIOS settings are causing conflicts. Pay attention to settings related to power management and boot options.
   []Hard Drive Issues:
   • Run diagnostic tests on your hard drive to check for any errors or issues. You can use tools like CrystalDiskInfo or HDDScan to assess the health of your hard drive.
   []Faulty Hardware:
   • It's possible that one of your hardware components, such as the motherboard or hard drive, is faulty. If possible, try testing your components on another system to see if the issue persists.
   []Memory Issues:
   • Run a memory test using tools like MemTest86 to check if your RAM is functioning correctly. Faulty RAM can cause system instability and unexpected shutdowns.

     Next Steps:​

   []Verify Component Compatibility:
   • Check the compatibility of all your hardware components with each other and with Windows 7 x84.
   []Update Drivers:
   • Ensure all drivers, especially the graphics card driver, are up to date.
   []Test Hardware Components:
   • Perform individual tests on your hardware components to identify any faulty parts.
   []Check System Event Logs:
   • Look into the Windows Event Viewer to check for any specific error messages or events that might provide more insight into the shutdowns.
2. Consult Manufacturer Support:
   • Reach out to the manufacturers of your components for further assistance, especially if your issues persist. Given the repeated installation failures and the symptoms you described, it's crucial to methodically troubleshoot each component and software aspect to identify the root cause of the problem. If needed, seek assistance from technical support or a professional to help diagnose and resolve the issue.
