Question PSU Clicking, PC wont boot

[vatttt]

Over the last three days, my pc has been refusing to boot properly. It starts to boot(PSU click), then shuts down(PSU click), and repeats the cycle. On the first day, I seemed to resolve it by turning off the power supply and then turning it back on, and it worked fine the entire day after that. On the second day, the same issue occurred, but this time just doing that didn't do, reseating the RAM in a different slot seemed to fix it. Yesterday, I encountered a similar situation, where turning off the power supply and leaving it off for a while allowed me to successfully boot. At the end of the day, instead of turning it off, I put it to sleep. However, today, the problem has resurfaced. On all the mentioned occasions, the PC booted and worked without any issues throughout the entire day.

Specifics of the Issue:

• PC attempts to boot, then shuts down and repeats.
• PSU clicks when it tries to turn on and clicks again when trying to turn off
• EZDebugLED on the motherboard shows a white light on the CPU section during failed boot attempts. Note: This LED typically lights up when booting the PC normally, so it might not be directly related.

Additional Information:

• Power supply is relatively new, purchased in February of last year. I had a faulty power supply before that would make my pc shut down under load, and eventually just wouldn't turn on, and am worried that the use of it could've damaged my motherboard.
• Temperature readings seem normal.
• Recently when I went to clean it I realized that the the back side panel was not closed properly and I suppose for that reason I was literally shocked (was shocked with it on, was shocked with it off, was shocked with the PSU off, and wasn't shocked when I plugged it off the wall) when touching the metal part of the back of the case, but upon closing the panel properly after cleaning and everything I wasn't shocked anymore ever

System Components:

• GPU: ROG Strix RTX 2060
• CPU: Intel I7-8700
• RAM: 1 stick of 16GB (I frankly do know know where it is from)
• PSU: Seasonic G12 GM-750 80 Plus Gold
• MOBO: MSI B360M Pro-VDH
• All components, except the PSU, were purchased in April 2019.

Is it safe to leave the PC attempting to boot on its own, or could this potentially cause further damage?

Any help or suggestions would be greatly appreciated. Thank you!

You should not be feeling shocks from your pc, other than static electricity. Somewhere your pc is not grounded properly. It could be the psu, a split wire, or the motherboard itself is not grounded properly. Since this is new from the psu being installed I would start with the psu and its connections. Then check the wires to make sure they a connected snuggly and that there are no cracks in the wiring or connections.

Is this a machine you built yourself, or a complete machine you bought? Your symptoms certainly indicate a short circuit somewhere that drains a power source. ONE cause of that is improper locations of the stand-offs that hold the mobo away from the back plate of the case. If you know all about that and are sure they are OK, ignore this idea. But if you need more info post back here.

This is a machine I bought, but I have installed a hard drive, changed cooler and changed PSU, so I've tinkered with it a little bit, though I don't know about what standoffs you're talking about can you tell me more?

Yeah, though I only experienced that before cleaning my pc and putting the side panel correctly, after that there were no shocks, though that makes me think that the electricity that was shocking me is now going somewhere else and preventing the computer from booting, I'm going to check the cables and psu as soon as I can

If you bought your machine from a store or some place that knows what they are doing, it is VERY unlikely that stand-offs are your problem. It IS an issue for some who build machines themselves without knowing how to deal with this issue.

Briefly, stand-offs are short pieces of metal that are installed between the mounting plate of your case and the back side of your mobo. They are there to establish a space gap between the bottom of the board and your case. They MUST be located ONLY right under the mounting holes of your mobo (usually three lines of three holes each), and the screws through those holes into the stand-offs create Ground points for your mobo. It is INTENDED that the mobo be grounded at those points and no others (except that there are Ground connections in the main Power Supply connector from your PSU).
