ASUS Motherboard installation guide 3-5
3.2.2 Failure to boot-up; No screen display
Most boot-up failure and no screen display result from device defection or incorrect
installation. Follow the instructions below to fix the problem.
1. Ensure that all the power cables are attached, including the system and the
monitor.
2. Ensure if the problem comes from expansion devices.
• Remove all the expansion card and devices. Use only motherboard,
monitor, VGA card, memory modules, power supply unit, heatsink and
fan, keyboard, and mouse to reboot the system.
• If the system is working normally, it is one of the expansion devices that
causes the problem. Reinstall the expansion devices you removed back
to the system one by one and find out the defective device.
3. Ensure if the problem comes from the basic system devices.
• If you have some spare devices, you can replace the devices in turn
to find out the defective device in the order of “memory module, CPU,
motherboard, hard/optical disk drive, keyboard/mouse.”
When you find out the defective device, contact your device retailer for service.
3.2.3 Failure to enter the operating system
1. If the problem emerges after you add a hardware, remove the newly added
hardware and reboot the system. If the system is working normally without
the hardware, the device may be defective or incompatible with the system.
Contact the device retailer for help.
2. If the problem emerges after you install a software or driver, follow the
instructions below to fix the problem.
a. Enter the operating system in safe mode and remove the software or
driver.
b. Contact the operating system company for further support.
c. If the previous instructions fail to fix the problem, you may need to
reformat your hard disk drive and reinstall a new operating system.
3. If the problem emerges after you change the BIOS settings, reboot and enter
the BIOS to load the setup defaults. Refer the motherboard user guide for
details.
