I found something interesting for you. If anyone has suggestions, I’ll share the steps I’ve tried. I recently purchased an i7 10700K because I was tired of the recurring problems with AMD products. After dealing with the FX-8350’s lawsuit over misleading ads and the Ryzen 7 2700X’s early performance concerns, I opted for a Team Blue motherboard for better reliability. My girlfriend got me an MSI Z490 Pro-A to pair with it. I assembled everything carefully, powered it up, but it wouldn’t turn on at all—despite a working PSU. I went through several troubleshooting actions: removed RAM to a single stick, switched power outlets, re-seated connectors, reinserted the CPU, cleared CMOS, and even connected the PSU directly from the back while powered. I also updated the BIOS. Once I connected the PSU, the board started booting but got stuck during the CPU initialization phase. The cool thing was the power switch worked, but only after the board had already powered on. I could even shut it down with the switch, yet not turn it on without it. The BIOS displayed everything correctly—Intel i7 10700K, 32GB 3200MHz DDR4, RTX 2070, all frequencies normal. I’m worried about repeatedly having to jump the PSU every time I want to use my PC, especially since this is the second time I’ve faced issues with MSI components. I’m hoping someone has alternative ideas before deciding to return it.

Ignore it, I'm not smart enough. The issue was the power supply all along. I tried another one and it started working perfectly. It seems I should buy a new PSU soon.
