asked

I have a Dell Inspiron 580 PC and a Dell ST2420L monitor from 2011. After not using them for a year, I recently tried to set them up but encountered issues: the PC continuously beeps (a series of four beeps in each sequence) and the monitor displays 'DELL.COM' then 'MESSAGE Entering Power Save Mode.' I have a Microsoft wireless keyboard and mouse with fresh batteries and the 2.4 GHz receiver inserted in a USB port. What could be causing these issues and how can I troubleshoot them?
