Instructions to fix red screen error on Windows 7. Unable to start Windows, the screen shown in red are the two hallmarks of this error. However, according to statistics, the majority of computer users who make this mistake are ASUS customers – especially those who use the Mainboard from 2014 to the present.
Why is the computer screen red?
According to technical analysis, the red screen error on Windows appears because the ASUS has enabled Secure Boot mode – a feature that helps users protect themselves from hacker attacks. However, because Microsoft released a new update for Windows 7 that did not come with support for Secure Boot, resulting in a system crash, the computer appeared red on the screen and could not be restarted.
