The screen just freezes, no reboot or bsod, i have to reset the machine. Drivers are all upto date.
So you mean that the OS, programs, and demain remain on? One frozen screenshot?
I've got something almost, but not quite, similar. Freezes after some usage. But, the cursor of the mouse is still moving. Occasionally some keys (Win-key) might work too, but not continuously. And eventually all input freezes. The only way out is to cut off power.
No observed freezes while running IBT or memtest86+.
I did flash to 1253. No help. I did remove Auzentech Forte soundcard. No help.
I did disable all energy saving options of Windows 7 and disabled Windows Defender that was simultaneously on with Avira antivirus tool. Now it took three evenings of usage before a freeze. This last freeze was while playing X3 Reunion. On freeze a (repeating) static sound started. That was yesterday.
Today, first boot froze on loading Windows. That had never happened before. Next boot was my first ever double-boot, no video, and no progress.
The memory led was on. Pressing MemOK inits testing, power cycles once, and reaches rapid blinking, then returns to solid led. Repeatably.
Memory was two sticks of Corsair CMV4GX3M1A1333C9, ie 2x4GB, in slots A2 and B2. Removing A2 and moving B2 to B1 allowed MemOK to succeed after multiple reboots.
I did restore Optimized Defaults, flashed to 1204, restored defaults, pulled out power cord and battery for several minutes (never touched battery of any board). Tried using both modules again, but failed, so am now running
with only one in A2 slot.
Haven't disabled C3/C6 (yet).
The more or less freezing system was in use for about seven evenings before today's solid memory error led.

EDIT: The second memory module no longer functions even when put in alone. Conclusion: that particular module was so and so to begin with (did pass couple cycles of Memtest86+ and linpack) but has failed (at least by P8P67 Pro standards).
