Random Power shutdowns During Boot/Idle/Games PSU? CPU? RAM?

[1Bradshaw1]

Hi! So, pretty much, my Computer is Randomly shutting down!

No minidumps are created, and no BSOD!

Eent viewer says Kernel Power 41!

But its not software as the crash happens sometimes, immediately after i turn on my system, Prior to BIOS!

Specs:
OS Windows 7 Ultimate x64 CPU Intel i7 920 2.66 GHz Motherboard Gigabyte GA-EX58-UD3R Memory Patriot 6gb (3x2GB) 1600 MHz Tripple Channel Graphics Card(s) Nvidia PNY GeForce GTX 460 768 mb Monitor(s) Displays LG Flatron W2361V 23" HD Hard Drives Western Digital 640GB PSU Novatech PowerStation Modular 750w 80+ CertifiedI have run Prime, temps are fine for CPU! I have tried all 3 ram Sticks in all modules singularly and the crashs still occur!

Tired my GTX 60 and ATI 4870 and still crashs!

Tried re-applying Thermal paste on CPU and no change!

The only thing i can think of is either, HDD , Power supply or re-seating CPU!!

Please help!!!

CHeers, Tom

Hello Tom, Welcome to SF!

Sounds like mobo or PSU.... but it could be something else..: OC-ing...

This board is often OC-ed using the Cloud or Hotkey OC. Please confirm you are not OC-ing?

Second is that your board has an awesome feature capable of powering iPAD's etc. If you use that, please (as a test) don't.

Finally, please, even though you have no dumps, please post full info as instructed here: http://www.sevenforums.com/crashes-debugging/96879-blue-screen-death-bsod-posting-instructions.html

Sometimes we get more out of the logs and the drivers you use...
