This issue is resolved now. I received the 5 Beeps error later - CMOS Battery Replacement.
I have Dell Inspiron 2020 All in One Desktop.  Today it suddenly turned off (probable cause is overheating) and since then it's turning on. When I press the power button, it suddenly stops after the amber light. I have recorded the video:  Video 1 [URL]  I tried following troubleshoots: 1. Removed both RAMs, one by one to check if they are causing issue 2. Removed BIOS battery for 10 min and tried restarting again. 3. Did Power Drain by pressing Power Button for 10 seconds Now, it is trying to restart on its own  right after I plugin the power chord (Please see the below video) Video 2: [URL]   Please let me know what could be the probable cause and the solution for this
