I build my first PC and am having a problem with my boot power up right after I turn on the power supply (either from the back switch or directly plugin it in).The system will power on for 2 seconds, will shut down immediately for 3 seconds, and then power up and boot up normally. After, the computer will stay on with no problem. Also, if the system is restarted or shut down and booted immediately, it starts up without power interruption. I am let to believe the power supply is faulty, specifically the capacitors are not holding up.
Any additional information or experiences in resolving this will be appreciated.
