Old enough to use it.
And the first couple hits on google pretty much covered it.
It is not the only thing that will cause a boot loop though.
Ram
GPU
Drivers
Motherboard
Corrupted bios
A bad HD
Will all cause a boot loop. Process of elimination is the only way to isolate it. Going off the information given, to the best of my ability, I would go with PSU first, then the board. Without the rig in front of me all any of us are doing is educated guessing anyway. My procedure would be to start with only the CPU only in the board and see if it loops. If it does, it pretty much narrows it down to PSU or board. If it doesn't, you'll need known good parts to sub in for further testing.
Wouldn't he also need a stick of RAM? Essentially, I piece together a minimum bootable system (CPU, board, 1 stick of RAM, PSU, keyboard, mouse and monitor), and if that doesn't work, I move the RAM to all other slots. If that doesn't work, I try a different stick of RAM in the same fashion. If it still boot loops, it's usually the PSU, board or CPU.
Before you try all of that though, is there anything connected to the front panel I/O? I've seen grounding issues on front panel USB cause boot loops, and that would be an easy thing to troubleshoot.
