Reasons and solutions for the computer not being able to stand up

First, the device driver (such as the optical drive) is in use, and the optical disc in the optical drive should be taken out.
Second, a software is running, or a driver has compatibility issues. After installing the new operating system, do not install other software and drivers, and do not perform any "optimization", immediately check if you can enter the standby state. If it is a driver issue, please upgrade to the latest version.
Third, there is a problem with the IDE controller driver. Install the motherboard driver immediately after installing the operating system. This driver can be found on the CD that came with your motherboard. Also try installing the latest motherboard driver.
Fourth, there is a problem with the hard disk itself. First, run “Disk Scanner> Check the hard drive and run the antivirus software to check the system. Secondly, unplug the power cord to open the chassis and unplug all the hard drives, optical drives, and even floppy drive data transmission lines except the main one. If the problem still cannot be solved, let the hard disk and the optical drive use separate data lines respectively; check whether the hard disk and the optical drive jumper are correct; make sure the data line is not damaged and tightly connected, and so on.
Finally, if the model of the hard disk or CD-ROM drive is earlier, it may not be able to support the advanced standby mode well. In this case, you can first set the CMOS "Power Management Setup" within the "ACPI Function" setting to "Enable". ;,“ACPI Suspend Type” set to “S3(STR)”Try
