It’s an older setup, but could it function? The reason I replaced the PSU wasn’t just because it was failing, but to add extra capacity so the previous unit wouldn’t be pushed beyond its limits.
If your friend is using a motherboard with debug LEDs, you can observe the stage it's stuck at during the POST process. A parts list would be useful. Because a motherboard speaker is connected, it should also emit POST error beep codes—a sequence of short and long beeps. You can then search for the meaning of<|pad|>'s beep codes (such as RAM problems or GPU errors, etc.).
