Windows 7 Cannot login to Windows, User Profile cannot load and Screen Hang

[wman]

My screen hanged and turned black, some desktop icons reappear when I move the mouse around. http://i.imgur.com/tZWSakr.jpg

I pressed the restart button to restart, loading slow and waited at the 'welcome' and 'preparing your desktop' for a few mins and finally reached inside windows desktop black screen and showed error popup http://i.imgur.com/vtS6BoE.jpg http://i.imgur.com/ItQuHNc.jpg http://i.imgur.com/o1TTU1R.jpg

I pressed the restart button to restart again, and this time it cannot login, it showed me a "The User Profile Service failed the logon, user profile cannot be loaded" error message http://i.imgur.com/qzQwOpc.jpg , pressed restart button few more times and same thing happened. Unplugged harddisk wire/connector and replugin to ensure firm connection, restart and still have the same problem.

Restart PC and pressed F8 when PC starting up to go to advanced boot options, tried "repair your computer" and tried again "last known good configuration (advanced)" http://i.imgur.com/K14mggc.jpg , tried all the options in "repair your computer" http://i.imgur.com/9cfyFuI.jpg but did not solve the "The User Profile Service failed the logon, user profile cannot be loaded" problem

Tried Method 1 in this article Link Removed but it did not fix the problem, so now I am unable to login and stuck with the error "The User Profile Service failed the logon, user profile cannot be loaded"
I can only login to safe mode. Sometimes it is slow and hangs in safe mode too.

Please help. Thanks.

It appears that your Windows system is encountering multiple issues, including the "The User Profile Service failed the logon, user profile cannot be loaded" error along with instances of BSOD and distorted colors on the screen. Here are some steps you can take to address these issues and attempt to resolve the login problem:

Fixing "The User Profile Service failed the logon" Error:​

1. Boot Into Safe Mode:
   • Since you can access Safe Mode, try to create a new user account in Safe Mode. This new account may allow you to log in successfully.
   []User Profile Fix:
   • In Safe Mode, use the Registry Editor to fix the user profile. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList, find the profile with .bak at the end and remove the .bak part.
   []System Restore:
   • Perform a System Restore in Safe Mode to revert the system to a point where it was functional before the login issues started.
   []SFC Scan:
   • Run a System File Checker (SFC) scan in Safe Mode to repair any corrupted system files. Open an elevated Command Prompt and run sfc /scannow.
   []Check Disk:
   • Run a Check Disk (CHKDSK) scan to check and repair disk errors. Open Command Prompt as administrator and run chkdsk /f /r.

     Addressing BSOD and Screen Issues:​

   []Analyze BSOD Errors:
   • Analyze the error codes displayed on the BSOD screen to identify the root cause. This information can help pinpoint the specific issue causing the crashes.
   []Update Drivers:
   • Ensure all drivers, especially graphics drivers, are up to date. Visit the manufacturer's website to download and install the latest drivers.
   []Hardware Check:
   • Verify that hardware components such as RAM, hard drive, and graphics card are all functioning properly. Consider running hardware diagnostics to check for any faulty components.
   []Checking for Malware:
   • Perform a thorough malware scan using trusted antivirus software to rule out any malicious software causing system instability.

     Additional Tips:​

   • Backup Data:
   • Before attempting any major changes, ensure important data is backed up to prevent data loss during troubleshooting.
   • Professional Assistance:
   • If the issues persist or if you feel unsure about troubleshooting steps, consider seeking help from a professional technician or reaching out to Microsoft support. By following these steps, you can work towards resolving the login issue, BSOD errors, and screen problems on your Windows system. If you encounter challenges during the process or need further assistance, feel free to seek additional guidance.
