I am having a problem and I am not sure sure how to solve it. As stated in the title, the computer turns on automatically, beeps then shuts down. I have tried clearing the CMOS through the jumper way, but that does not seem to work. I am going to get a new lithium battery to replace the CMOS the battery way, but I am not confident that will work.
I am not sure if it's an overheating problem as the computer has been turned off for hours and still shuts down automatically after the beep. I have tried unplugging everything like keyboard, mouse, etc. except the power cable but I am still having the same problem.
I have tried using an old PSU but I am not sure if I am connecting everything correctly with that one as it has different cables to my current one.
The computer boots up automatically after I switch on the power switch at the back of the computer, beeps then instantly shuts down. If I leave the power switch on, it repeats the boot up, then beep, then shut down problem every few minutes.
PSU is an Antec Neo ECO 520C.
I think the motherboard is Intel D60188-001. I think the Graphics Card is a Gigabyte N14180. I think the RAM is a Kingston KVR667D2N5/1G.
All Hardware except the PSU I think is at least 8 years old. PSU is 4 years old. I had to start using my old graphics card recently as my newer graphics card stopped working properly.
I have tried reseating the RAM, removing the hard drive and inserting a Windows installation CD but the problem still occurs.
