The 3 dumps seem to indicate
memory or a driver as most likely to be the cause.
Drivers that need updating or uninstalling:
AsIO.sys Asus PCProbe Utility
ASUSTeK Computer Inc. -Support- Drivers and Download
ASACPI.sys Asus ATK0110 ACPI Utility (a known BSOD maker in Win7). Also a part of the Asus PCProbe and AISuite Utilities
ASUSTeK Computer Inc. -Support- Drivers and Download
cpuz135_x64.sys CPU-Z CPU monitor
CPUID - System & hardware benchmark, monitoring, reporting
nvBridge.kmd nVidia Compatible Vista Kernel Mode Driver (likely belongs to
nForce chipset drivers)
Drivers - Download NVIDIA Drivers
RTKVHD64.sys Realtek High Definition Audio Function Driver
Realtek
l160x64.sys NDIS Miniport Driver for Atheros L1 Gigabit Ethernet Controller
ATHEROS drivers for Microsoft Windows (Atheros?????)
Uninstall any motherboard utilities (like ASUS PCProbe) - that
should fix the first 2, then uninstall CPU-Z and update those hardware drivers.
Run a Memtest86+ diagnostic overnight, as many as 7 -10 passes would be good -
any errors and you'll need to check each memory stick individually, the single stick(s) should all be tested from Slot 1.
Memory Diagnostics
If the memory checks out as good, keep using the PC until it gives another BSOD and then upload the dump (copy the latest dump(s) from C:\Windows\Minidump, to the Desktop then zip and attach the resulting zip files).
