Hey all, I posted about a booting issue with a newly built computer that had been running for about a week before it stopped booting. I'll paste the post below for anyone that wants to see the specifics of the problem. TL;DR is that it was working for a week with no noticeable problems, was shut down normally, then simply wouldn't power on a few hours later. I tried a number of things, one being the paperclip test on the PSU and it failed that (though the standby power lights on the mobo and gpu will still come on while plugged in so maybe I botched that too). I tested the ram, checked the cable connections, tried powering it on with only the cpu, ram, and ssd, all to no avail.
Since then I've ordered a replacement PSU and a new surge protector but honestly I'm really worried there's an underlying problem that caused the first to fail and will cause the second to fail as well. If it died during use it might be easier to pinpoint but as far as I could tell everything was fine when I turned it off and it just up and died in its sleep. Didn't touch the case, didn't move anything, didn't unplug anything, just shut it down and came back later to a dead machine. It's my hope that recent bad weather combined with a bad power strip caused a short, but seeing as it's a newly built machine it feels like it's far more likely that I botched something with the setup that's now sabotaging the system.
Anyhow, apologies for the wall of text, my main question is 'if someone told you their power supply died after a week of use, what would be the first thing you would suspect?'. I'd really like to take all the precautions I can so I don't fry this PSU as well, but given the trouble diagnosing the original problem I'm not really sure where to start.
Original Post Below---------------------------------
I recently put together a desktop but have run into an issue where it will no longer power on. I'm having a hard time pinpointing the problem since it was working just up until a few hours ago.
I shut down the computer normally, no issues with it while running that I could see. A few hours later I went to turn it on and nothing happened. The motherboard standby and GPU power lights are on when plugged in, but nothing happens when the power button is pressed. No fans, no beeps, no reaction whatsoever. I had been using it for about eight hours a day for roughly a week prior, shutting it down at night and turning it on in the morning.
What's been tried to no result:
Bridging the gap between the pins of the power switch
Pressing the manual power button on the motherboard itself
Disconnecting the GPU to reduce load on PSU
Optical Drive: Asus 24x DVD-RW Serial-ATA Internal OEM Optical Drive
OS: Windows 7 Professional 64-bit
I've read that it's most likely the PSU or Motherboard but was hoping that the specifics of the issue might make it easier to narrow it down, or find other possible solutions before spending money on a new part. Thanks.
