OK, I have just build my own computer. its an AMD 2500+ Barton. i have everything set up in it, but, as most of you probly kno, most computers run of 115v. mine will not. When i do have it on 115v and then i turn it on, it only stays on for a split second before shuting its self off. So i switched it over to 230v and it worked..it was running. yay. untill i smelt a smell no computer guy wants to smell. the smell of electricty burning through something. so i shut it donw right away and started flipping out. haha jj. but i was like *censored*..so then i waited awhile and started it back up again. then i put my head near the power supply and it was making some weird noises, almost as if it was working too hard, and then...i started listing to the CPU fan. and it was like shuting off and turning back on....ok so, im not a computer guru but the only thing i can come up with is that the power supply isnt strong enough...its a 400watt though, i dont know what to do...please help me out
