I built a PC for my mom recently and tried to turn it on. The BIOS screen didn’t appear, only the LEDs blinked briefly before fading. I’ve verified the power cables and reattached the CPU and RAM. I’m stuck and considering swapping out the motherboard. Do you know anyone else faced this issue? Any suggestions could be helpful. Thanks.

Details: i3-10100f, 16GB DDR4 3200, mid-2000s graphics card for display, EVGA 450 W3 PSU, MSI H510M-A Pro board, PNY 500GB SSD (Windows already installed). Updated Nov 14, 2022 by CRUZ_

Ensure the CPU fan is linked to the CPU fan connector; otherwise, the motherboard may power down right away if no connection exists.

I recall feeling really annoyed because I didn’t understand why my computer wouldn’t power up, only to discover the CPU fan was linked to a case fan header, leading to automatic shutdowns whenever I attempted to start it.

It matches the correct header.

I've connected both CPU and case fan headers to their proper locations.

I understand that many believe any PCIe GPU fits any PCIe setup, but my experience shows otherwise. Recent UEFI systems may not always align with pre-UEFI-aware GPU firmware, or in some unusual scenarios the BIOS failed to properly reduce speeds below PCIe 3.0 for a 2.0 GPU. It’s wise to consider either a more modern GPU for testing or a non-F CPU setup—especially if you only need basic video output.

ok so I have actually tested it with a GTX 560 and I still didnt get a video out. also I think the ez troubleshoot LED for video out on the motherboard would light up if it didnt work right? should I test something even more recent than the GTX 560?

It seems you're questioning why a newer card isn't causing power issues for the PSU.

Recent options include Nvidia 700-series and AMD RX4xx cards. These have performed well in the past couple of years. Running idle should still work for testing.
