Had a client's PC with a weird boot loop, swapped the PSU and it was fixed in 20 minutes
This older desktop in our shop was stuck restarting right after the BIOS screen. I spent an hour checking RAM, the drive, and even re-seating the CPU. Then I swapped in a spare Corsair CX550 from our bench, and it booted straight to Windows. The old PSU tested fine on a basic tester, but under load it must have been failing. Has anyone else had a PSU pass a simple test but still cause a boot loop?

Yeah, the part about it passing a basic test but failing under load is so real. My buddy had that exact thing with his gaming rig. It would turn on, lights and fans would spin for a second, then just die. His cheap tester said the voltages were okay. He finally borrowed a proper PSU from another friend, swapped it in, and it fired up like nothing was ever wrong. That old unit just couldn't handle the startup draw anymore.

Man, why do I always forget the PSU first? I'll spend all day on software and memory tests before it hits me. That story from @paigesullivan about the gaming rig sounds way too familiar. I guess those basic testers just check if it's alive, not if it can actually do any work. Makes you feel a bit silly after you've tried everything else.
