Friends computer keeps rebooting.

[Azureth]

So my friend built a new computer about a month ago and kept it over at my place since he doesn't have good internet at his place and it worked fine, however he took it to his other friends house and says when he tries to start it up it only stays on for like a second then turns off. I asked him if any of the cables came unplugged or were loose and he said no, and said he didn't drop it or anything. Any ideas?

Maybe it's an electrical problem, local to the friend's house.

Maybe the friend rode the tower case like a matador on a Sunday night.

It sounds like a Power Supply problem.

it keeps turning off and on, weird how it happened as soon as he moved it, and it does it at his house.
