PC turn off immediately after turning it on
Im having problem with my pc lately.
My pc spec :
Rog strix B660-i
I5 14600kf
Corsair vengeance 5600mhz
Rtx 3070ti strix
Corsair SF750 with custom cable
First thing first, i was swapping my lp air cooler to aio and after it done, my pc just wont turn on. It just turn on for a second and then turn off immediately.
What i already did to troubleshooting is
Reseating ram
Reseating gpu
Reseating cpu, 24pin dan pcie cable on both end.
But its still not solve the issue, my pc keep turning off after a second. And then i try to dissconnect riser from pcie slot with pcie cable still intact and it could turn on! Then i turn it off again and try to put riser on pcie slot and sadly it goes back turn off just a second.
I’ve been searching on how to fix this issue from forums and yt videos and most of the comments suggesting it was psu. Tbh i have this same issue a few month earlier and solved it with reseating ram and also had a few another issue like suddenly restart, my pc cause power trip (after cleaning and rebuild) but its very rarely happen.
Right now i’m sending my PSU for RMA and hopefully just as other suggested.
But i also suspected the mobo pcie slot, riser cable, psu cable custom and the VGA itself.
Is anyone had the same issue? Any suggestions on how to fix it?
Thanks
