Help!! PC powered off after 30 minutes of use of newly built system :(

[wolf1978]

Hello,

I just received my new pc parts yesterday. Installed it all and it ran like a champ long enough to install windows 7. Approx 30-40 minutes. As I was downloading drivers it shut completely off. I went to turn it back on and the fans would come on then go off . I was working great and the cpu temp in the bios read 43C so it looked good there when it was working. There are no beep codes also so I am not sure whats going on??

System Specs:
CORSAIR Vengeance 8GB
CORSAIR Enthusiast Series TX650 V2 650W
Intel Core i5-2500K Sandy Bridge 3.3GHz
MSI P67A-G43 (B3)


Things I have tried
* Cleared the Cmos from the back of the motherboard. It now turns on with fans running one LED light but no video
* Removing both ram sticks (2x 4gb) and putting each one in seperately
* Switched out video cards and even moved it to the other pci express slot
* Took heat sync off and took cpu out and put it back in to ensure it was seated correctly.

I don't have another power supply or motherboard to test with. Since there are no beep codes I am beginning to think that either the motherboard went out or maybe the power supply?

Anybody have any ideas as to what maybe happening. I greatly appreciate it!!

test with another PSU

I do have a older 550 watt power supply I could try. Its an antec version 2.0. That should be enough to test with ? I could put in a older video card that wouldn't sap the power... hmm this is frustrating

I had the same problem when I upgraded.  In my case it definitely was the power supply.  In my effort to figure out the problem by swapping components in and out, the dieing power supply killed 2 P8P67 Pro and 2 2500k, and when I tested with the P67A-GD65, the power supply totally died, but the good thing is that the GD65 survived.  Swapped in a 430W to test and everything was perfect.  At full load with GTX260, it will draw less than 300W, so your power supply is fine to test.

Thank you for the heads up glad you are up and going now. i'll  I hope it didn't kill my proc or board but i'm starting to wonder. I just got them so can RMA it if needed . I will try the other Power Supply

Update:

So I switched to the older power supply and video card and at first it wouldn't boot but I could see all the cpu led's lit up so it looked different. I pulled the CMOS battery for 15 mins and put it back in and it fired right up! The motherboard appears healthy so far and I did a processor diag from intel and it passed and my ram passed with the bios memory check. I will just RMA the power supply for now.

Thank you all for your help!
