Desktop getting power, but not connecting to devices

Hi @loui1024 ,

Some things to try as you haven’t mentioned what you have tried to do

Try removing the graphics card and connecting the monitor to the onboard video output and check if there is a display or not.

Try connecting a pc speaker to the speaker header pins on the motherboard and listen for any beep error codes when starting the desktop.

Here’s an image showing what I mean.

Here’s a link that details the beep error codes for a no display problem. Depending on the beep code, if any, and they are not shown in the link, you may have to search the internet to find out what they mean. Just search for Asus desktop (insert beep code) to hopefully get results for what it means.

If you haven’t already done so, try clearing the BIOS back to default in case it has become corrupted somehow.

Here’s an image that shows how to do this. Do it by removing the RTC battery (remember which way is it installed so that you reinstall it the correct way, usually it is +ve on top) from the motherboard as this will ensure that there is no power to maintain any settings that may be corrupted and so restore all settings to their default values.
