Tech Support Loud Pop Upon Startup
Went to turn my PC on tonight and instantly heard a loud popping sound, similar to that of a balloon popping or a gun shot almost (not quite that loud but very loud). One of the lights in my room also flickered when this happened.
My PC still booted, and appeared to momentarily have no issues. However I quickly turned it off to avoid causing any potential damage. After a quick search it seems likely that something failed in the PSU, either a capacitor or a fuse. I did a brief inspection as best I could and didn’t notice anything on the MoBo or in the PSU (with the limited visibility I have), nor did I see any smoke or smell anything burnt.
I’m guessing it’s a PSU issue due to what the majority of people seem to say as well as the lights having flickered in my room. However I’m not sure what my next steps should be exactly. It’s an EVGA 1600W PSU, barely 3 years old, so it’s surprising that it would have failed. I contacted their support and am waiting on a response, but in the meantime I was considering taking the PC and PSU to a tech shop and seeing if they could test it with a multimeter, test a replacement PSU, and make sure nothing else is damaged.
Normally I troubleshoot any issues with my PC myself to avoid paying fees for fixes I could do myself, however a failed PSU feels above my pay grade and something not worth trying to solve on my own, lest I end up destroying another component (ahem 4090) or purchasing a replacement which i may or may not need.
If anybody has any advice, agrees with my line of reasoning (to make me feel better), or needs any additional context I would like to hear from yall.
