I've had my PC for four months now, and it's been working just fine until the last couple of days. Out of nowhere, it completely shuts down within minutes of booting up, without any warning signs like throttling or freezing. The CPU temperatures are normal, and it usually happens when I'm just browsing or watching YouTube, not during gaming sessions. After it shuts down, I can start it up again right away, and it won't shut off for the rest of the day. I tried cleaning out the dust with an electric air blower, including the PSU's fan and air filter, but I'm not sure if that's the cause. Here's my build: GIGABYTE B650 EAGLE AX, AMD RYZEN 7 7800X3D, GIGABYTE Radeon RX 7700 XT GAMING OC 12G, Kingston 1TB Renegade 7300/6000, Kingston Beast 32GB (2x16) DDR5 5600MHz CL36, MSI MAG CORELIQUID M240 CPU Cooler, MSI MAG A750BN PSU. Any thoughts?

You might want to check for any BSOD reports with a tool like BlueScreenView, even if it isn't showing a blue screen. Also, take a look at the Windows reliability monitor to see if there are any device errors logged. Sometimes, unexpected shutdowns can leave traces in there.
It could be a bad PSU. If the power supply isn't providing stable power, it might cause your PC to shut off suddenly without any warnings. You might want to consider testing with a different PSU if possible.
Totally agree, a failing PSU could definitely be the culprit here.
But if there's no blue screen at all, will BlueScreenView even help? I looked at the Event Viewer, and it said the shutdown was unexpected.
