P7P55D Memroy Problem - Page 2

Hello there.

I think i have a similar problem to y'all. Here is my config:
Antec P183
Seasonic M12D - 750W
Asus P7P55D
Intel® Core™ i5 750
Arctic Silver Arctic Silver 5
Noctua NH-U12P SE1366
Corsair TWIN3X 2 x 2 Go DDR3 PC12800 CAS 9
Gigabyte GV-N98TSL-1GI

The Cpu fits correctly in the socket, i've contacted Noctua to get a Mounting kit 2 (compatible with socket 1156). Everything's fine, Thermal paste has been spread (i've already mounted and unmounted several times).

I'v read this entire post which i found very useful and rich of various information.

The quickest way to explain my problem is to redirect you to a video i've made that shows better than a few words.

I've commented this in french, but basically all i say is a presentation of the pieces and the problem.

I might add that the problem is the same whitout memory stick at all. So it's more a cpu or a mobo problem.

I don't have a reset button on my motherboard (it ain't a pro/deluxe version) so i'm not sure how to clear the cmos. It has yet to be tried.

Any help would be very much appreciated.

- Edit -
I've found how to clear the cmos (jumper at the bottom), nothing changed.
I've tried my old PSU, which does NOT have the 8 pins 12V plug (top of the motherboard).
The CPU LED doesn't stop and so does the fans, so i guess it's a cpu problem and the new psu just stopped everything to prevent any damage.
What are the steps now ? I've already unmounted the stuff, i couldn't see any damage. I'm not sure what to do. I'll of course try to unmount and mount it again, see if there is anything wrong with the stuff.

Hey!

I don't know if your Chieftec APS-500S is responsible for your boot problems, but i can guarantee that the Thermaltake Thoughpower 850W is good to go.

I hope you'll find the solution to your problem.

Peace!
