Sorry for the dealy on my reply but i had a lot of work u_u
Well i ran all the Prime95 tests, OCCT, Intel Burning Test... all totally stable. The BSOD only happend when i leave the computer idle for long time (i didnt know the exact time, i think more than 15 mins).
I got a pic of the last BSOD (yesterday)
I think must be that my mobo or the OS is shutting down something and this causes the error.
The computer is:
i5 760 no OC
2x4Gb DDR3 1600 (runing at 1333 by default)
GTX 460 1Gb OC from factory
2 x WD Caviar Black 640Gb
1 x Seagate 1Tb
1 x SSD 64GB (OS)
Asus P7P55D PRO
All watercooloed, no leaks, so temperature is not the problem.
The other problem i think about is some kind of hardware incompatibility.
