Computer powers on for 1 second and shuts off

[Rhakatiri]

I bought myself a computer and everything worked fine for some months, but now my computer gets bluescreens randomly and I cant even turn it on now it just shuts off and tries to boot back on constantly. Everthing else works in the case, fans are spinning and motherboard has green light on (dont know what that means). But keyboard and monitor isin't powered.

PC wont make any beeps too when it boots up.

Doubt it's cause overheating as my temps were around 35 - 40. I have tried everything except taking everything apart and building it back up cause I got no idea what to do and dont wanna ruin the parts by accident.

Do the paperclip test to test the power supply. If you have any molex fans hook those up to it when you do so. Corsair has a good video on YouTube on how to do the paperclip test.

I had the exact same problem. I threw out that power supply and brought a Seasonic S12II 520W PSU and have had no issues since then.
