Did you try to change the CMOS battery? It is on the motherboard

 

[Nature_call]

i only tried to reseat the CMOS battery (as i dont have a spare) and restart it by switching and reverting the jumper but to no valid. CPU is only 2.5 y/o, is the possibility of low battery possible at this duration? any idea where can i buy the CMOS battery easily w.o going sls?

TIA!

is the casing fan still running or also stop like the cpu stock fan?

CMOS battery CR2032 is available at NTUC as well as most mini marts. I think your PSU is a gone case liao.

case fan behave like stock fan, start 1-2 sec and stops.

i think it's my PSU, but no way to test w/o spare. any other methods to narrow further before i buy a new PSU

try this first

remove all your ram and clean up the contact point then reinsert - if still cannot

use an spare psu and test :3

 

[nexusRAGER]

Try and run the cpu, mobo and ram only.

remove rest of the things.

you are using Seasonic should come with 5 years warranty right?

Why not bring to corbell and let them check?

Coldstorage/NTUC selling just ensure same model battery

Is confirm not due to battery.

If the battery is weak, the system will prompt him to go to the bios and will not shut down.

highly chance the psu gg. due to it cannot provide the enough power that why the system shut down.

TS should bring the psu to corbell to check assuming that his psu is as old as his rig.

I was in a hurry and wanna avoid the hassle of RMA. I went to a IT shop at causeway point and bought a master cooler psu 420 at $55. Plug it in and thankfully it works. I did not register my seasonic but got receipt. It's about 2.5 y/o so sayang, I rmb getting this brand despite it costing more. It lying on my house now, any idea what can I do with it?
