In addition, I have seen irregular powerdowns like this caused by the PSU.

Cheaper switching PSU's with unstable currents can be effected by other system compnents. Any system that cannot retain a stable 5v logic rail will fall over. Without special equipment it is not possible to accurately monitor power output.

In your scenario... I'd suggest either trying another PSU or... lighten your overall power load... ie USB powered dev's, drives, mem, adapters...

If the fault goes away... woohoo... if not.. well at least you ruled power out..

Glucky!

FYI - Harddrive motors can cause current fluctuations. In weakened PSU's this can result in crashes. It is suggested that hard drives be kept on seperate power lines from other devs... /fans/dvdrw/powered videocards... etc. Some manufacturers supply carbon cores to alleviate this problem.

i got a 485w enermax or somehting like that


and im not using much juice



i think the proc fan is not working up to spec, so im prolly gonna get an aftermarket fan :banana

have you checked the capacitors on the motherboard yet? my computer did something similar it would shut down after a random amount of time, but would shut down more often under a heavy processing load. it had swollen and busted capacitors. i'f your piece is workin at all your processor probly isn't the problem. also are you getting the correct voltage readings?

the 12v, 5v, and vcore ( i think 1.25v ) is actually overspec'ing, but not much. the 3.3v line is below, but thats how its been with all my comps


interesting thing is though, after we are done with using the computer ( its the family comp, but i bought, so if i move, it goes with me ) we shutdown normally, so this issue doesnt really persist anymore, and the asus utililty program "asus probe" doesnt show that big of a proc temp anymore ... highest ive seen in that utility is 76, which is a bit high for what i was doing, basically surfing ...


ill look at the mb capacitors later

well, i got a thermaltake cooler, maybe that'll do some wonders...

if not, next will be the mb caps...
