Lenovo G500 didn't respond when it started, and there was no code on the blue screen.

Dear Lenovo users, hello!

(1) If your computer uses the blue screen of XP system, it is likely that the BIOS settings are incorrect, and XP system does not support SATA hard disk, so just enter the BIOS at startup and change the hard disk to be compatible. If not, please check the blue screen information. Maybe the memory is not checked well, the hard disk is broken, and the motherboard is burned.

(2) If your computer uses the blue screen of Win7 system, you can set the system to clean startup mode for troubleshooting.

The specific setting method is to press win+R key, enter msconfig, select Disable All under the Startup tab, and select Disable All after hiding all Microsoft services under the Services tab (it is recommended to save the original startup items and service settings in the screenshot for easy restoration), and then restart viewing.

If the clean startup mode is normal, you can select the loaded projects and services one by one, confirm the projects that cause slow startup, and uninstall or disable the corresponding software. Specific methods can refer to:

I hope the above answers can solve your problem.

Thank you for your support to Lenovo and wish you a happy life!
