problem with 750tx

[jda78]

I've had this psu for about a month and a half. Today, i turn on my computer and it starts up through cmos and and i see the windows startup screen. about 4 seconds into this screen, everything goes blank and i have no response for 2 minutes. i hit the reset button and it was an instant shutdown. i waited for 15-20 seconds thinking that something might just need to be reset and i hit the power button. nothing, no blink of any lights or fans turning, nothing. i then proceed to turn the power switch off to the ps and waited for 30 seconds, if not longer. i turn the switch back on, wait 10 seconds and hit the power button. i get a half second of power to fans and lights and also a quick buzz (electrical short) sound from the psu. I wasn't sure at first, but then i went through the whole proccess again and sure as anything, i look into the back of the psu and hit the power button and see a very recognizable blue electric arc. i'm thinking that this is a psu failure because this was not the norm nor should it ever be the norm. my question is, should i just rma now or is there some other "magic" fix that you could reccommend? I really like this psu and it has more power than i will need for a good while. it was a rock-solid piece of equipment until today, and would really like it to be working now. please advise as t the least painful method for a working psu. :[pouts:

 

~NEWSFLASH~

Seems as though there is something on the MB that is shorting out. Tried another psu with the same exact results. Sorry to have posted here just to have solved my own problem. I'm just hoping all of the components are still in working order.

If another PSU is giving you the same results, then I would probably suggest replacing the motherboard. And if possible, you may want to test the PSU in a different system and see if you have the same results. If you still see the blue arc, we will want to replace the unit for you ASAP.
