Lock ups due to PSU?

[AssaTM]

Hey all, i'm asking for someone else, but when he plays Halo on Multiplayer, it's flawless, as smooth as anything graphics wise, but when he plays the story mode it locks up within a few minutes, one time the whole PC rebooted, but this only happened once, do you think it's the PSU being maxed out due to the more intense single player with the CPU working harder etc? or perhaps just Halo single player being a pain? i'll test other games the next time i'm there, but I just wondered what the general signs of a PSU being unstable are? Many Thanks to whoever can help

i doubt its the psu, as usually psu hitting its limit will cause the system to reboot (or blow up)

if ti works fine in multiplayer, chances are its not power being an issue in single player, as multiplayer is often more intense spec-wise, but the difference in power usage would be very minimal anyway.

Ahhh ok thank you, it's probably just Halo being a pain then, or a program interfering with it, as Halo isnt exactly the best coded port in the world haha, but Many Thanks for the help then
