Windows 7: Another bsod

I looked at all of the dumps (all the way back to April of this year), and your CPU is always failing to wake from a C3 idle state. Are we sure this CPU is working properly? Usually I see CPUs start having issues waking up from a C1 or C3 idle state when they've started to show their age (and if this is this really a Via C7-M CPU, that design is from 2005 / 2006):
Code:
kd> !sysinfo cpuinfo
[CPU Information]
~MHz = REG_DWORD 1596
Component Information = REG_BINARY 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0
Configuration Data = REG_FULL_RESOURCE_DESCRIPTOR ff,ff,ff,ff,ff,ff,ff,ff,0,0,0,0,0,0,0,0
Identifier = REG_SZ x86 Family 6 Model 13 Stepping 0
ProcessorNameString = REG_SZ VIA C7-M Processor 1600MHz
VendorIdentifier = REG_SZ CentaurHauls
If so, it could be the dual phase lock lookup (PLL) of the CPU that's potentially malfunctioning (it's responsible for switching in and out of low power states on the C7 CPUs). Given that the C3 state is a *very* low-power idle state, and these parts are known for causing wakeup issues in Linux machines with C3, it might be useful to disable the C3 state in Windows to see if it resolves anything - run the following command and reboot:
reg add HKLM\System\CurrentControlSet\Control\Processor /v Capabilities /t REG_DWORD /d 0x0007c044

Since I execute the command, no BSOD

I can do all the update too

Wait and see

Let us know - Since the beginning of August you were averaging about 1 every day or so, so if you go more than 72 hours without a BSOD I'd consider it resolved. I'd still say that CPU is on it's last legs, but this might buy you more time (how much more is anyone's guess) with that system before you have to consider repair or replacement.
