New build unexpectedly dies

[miller2112]

I just built a new system this weekend and fired it up Sunday.

Antec 300 case
i7 920
2 tb WD Green HDD
12gb Corsair DDR3 RAM
Nvidia Quadro FX3800
Corsair 850TX PSU

I installed Vista32 on it, no problems, it was humming along. So after I got all the drivers on it, I decided to shut everything down, unplug it, and open the case back up to work on cable management and airflow. I did not remove any of the main power cables, just used some ties to move them out of the Quadro and HDD's way. I also moved it back to the anti static mat and used proper grounding. So, when I got everything up to standards, I brought the case back to my office and plugged it in. When I flipped the switch.....nothing, zilch...nada.

No power, nothing, like a dead car battery. I opened up the case, re-plugged in the power connectors and also tried other outlets in the house. Could my PSU have died that quickly? Should I be concerned about the other components??

This is a little bit off the subject, but I hope you're aware that about 9GB of your 12GB of RAM is wasted with a 32-bit OS. I almost laughed out loud when I read 12GB and 32-bit OS in the same post.

Anyway, I would go through all the steps in this checklist to try to narrow down what's causing your problems:

yep, I realize that. I was going to dual-boot with Windows 7 64bit and use it for Solidworks and other optimized programs. Just putting Vista on first and then doing a partition.

You didn't turn the switch on the back of the PSU off did you?

try replugging everything back in all the cables power too
dvd hd 1 loose cable will stop it from starting

made sure that the switch on the PSU was off when i plugged in, then turned it to on and tried to fire it up...nothing, I unplugged all hardware except for the motherboard

I think the PSU is faulty because NOTHING starts, the fans the board, nothing

That might be the culprit do you have another PSU by any chance to power up the system?

i think I'm going to try and send this one back to Corsair, it shouldnt die like that after a few uses!

Maybe I'll buy a spare in the meantime
