I've got a prebuilt PC that I bought last year, and I've gone ahead and replaced several parts like the RAM, graphics card, PSU, and even the CPU recently. However, I'm facing an issue where my PC doesn't post about once every one to three boot attempts. When this happens, I have to force it to power off by holding down the button, and then it will boot up again, but I get a warning about a previous boot failure and have to access the BIOS. I'm really concerned that someday it won't boot at all, and I'm not sure what's causing this problem.

It could be that your power supply is failing. I had a similar experience where my system wouldn't post intermittently, and it turned out the PSU was on its way out.
Check if there are any error lights or codes showing on your motherboard. Sometimes they're hard to notice, but they can give you clues about what's going wrong.
That doesn't make sense since I just bought my PSU a couple of weeks ago, and it's a solid brand with 850W.
