Question PC suddenly won't POST

[davide_carella]

Hi, my PC suddenly started not POSTing giving no beeps and not showing any video output. The PC was working fine the day before this happened I didn't make any significant software or hardware changes.
This already happened in the past, but I fixed it changing the PSU so I'm excluding it from the possible issue since I changed it a few months back.

PC specs:

• PSU: Sharkoon WPM Gold Zero 550W
• MOBO: ASUS P8H61-M
• CPU: Intel i5-3350P
• RAM: Crucial 8GB DDR3 (1333 MHz)
• GPU: MSI nVidia GTX 1050 Ti
• SSDs: 2x 1TB Crucial BX500

If you remove the GTX 1050 Ti and use the integrated video controller, is there any change in behavior?

you have any q-led or error code you could give us on boot .

No same as before. I should mention though two odd behaviors. First of all I tried removing all the RAM and I wasn't getting any beeps to signal that there wasn't any RAM in the system (this leads me to think that it might be a MOBO issue?), and also I tried powering the PSU from a different source and it seemed to have worked but I tried it a second time as it was giving the same issue.

Nope. Unfortunately as you can see the components are very old and don't have any status LEDs I can check, just the buzzer.

Did you try a second PSU when the system seemed to work, or just a different power source (outlet)?

I'm sorry I meant a different outlet. I wish I had a spare PSU that would've been really handy.

Understood. So, it did work once when using the second power outlet. This would imply an issue with the PSU itself.

As I said, the PSU is new and I tried again with the second outlet and it didn't work so it doesn't seem there's a pattern there.

could you ask a find to test your psu in is system or the one he have in yours .
