This PC isn't starting reliably and requires advice.
Upgraded an older system by swapping in a new graphics card and linking the power cords. * The machine failed to start at first; a red indicator on the motherboard (ASRock H270M Performance) lit, but it wasn’t the diagnostic one. * After unplugging the GPU connection, the PC powered on, including the fans. Then reconnecting the GPU power cord allowed normal startup. **Changes Made and Verified**: * Installed additional RAM (started with 4x2GB Kingston Fury HyperX, added 16x2GB Crucial Ballistix), which functioned correctly. * Completed benchmarks and stress tests (3DMark) without issues. * Reinstalled a clean Windows version without bloatware after a fresh boot. **Booting Issues the Following Day**: The system refused to start despite several tries: * Removed GPU power cord, GPU, and added RAM; even after removing all RAM * Performed CMOS reset and used a screwdriver to short the power pins, but nothing worked. **Variable Booting with Power Switch and PSU**: * Tested various power button presses combined with PSU toggling. * One sequence succeeded temporarily: * Turn off PSU → Hold case power button → Turn on PSU → Release button → Press again to boot. * Another sequence: * Turn off PSU → Hold case power button → Turn on PSU (without releasing) → PC started. During the final inconsistent attempt, the motherboard’s red light flashed when powered on, but stayed off when shut down (PSU still active). This behavior is unpredictable, hinting at a possible PSU fault. I’d advise turning it off completely now to avoid potential harm to other parts. Specs: Intel Core i5-6500 Be Quiet!

Specs, please (It could be psu not being able to power the new gpu)
Never considered it before, really. Since it's a secondary PC, I could just replace it with another one if needed.
You're suggesting it might be a future problem rather than an immediate issue. You've already tried a different PCIe cable setup and still faced the same outcome. Right now, you're focusing on finding a second-hand PSU to verify your likely faulty motherboard. Updated October 28, 2024 by FrozenFruit
Hi, it looks like Leclod is assisting with a troubleshooting step. Try removing the smaller sticks and check if the machine starts more smoothly. If that doesn't work, swap them out and try again. Make sure to power down between each change. If neither solution succeeds, let me know.
