Solved Return of the BSODs

[badkarma11]

Well, the rig ran well for a few months, and now is crashing like a Valu-Jet all day yesterday and today. BAD_POOL_HEADER is the most common. Dump attached

Mate, you are geek ... you know what is what. I am just trying to assist you ... let me know your thoughts on those ....

Roll back your display driver.

• Download and install Driver Fusion.
• Reboot the computer in Advanced Boot Options, safe mode. Search Driver Fusion in your start menu, and remove all components of your nVidia display driver.
• Boot normally now. Go to Drivers - Download NVIDIA Drivers, Drivers > Beta and Legacy; search there with your cards particulars for GeForce 306.23 Driver, dated 13.9.2012 and install it.

Scan the system for possible virus infection.

• Anti-rootkit utility TDSSKiller
• Windows Defender Offline

Which network do you actually use?

• Realtek PCIe GBE Family Controller
• NETGEAR WNA3100 N300 Wireless USB Adapter
• Deterministic Network Enhancer Miniport
• Cisco Systems VPN Adapter for 64-bit Windows

All them need updating. Have a try?

Thank you, Arc. You are always here for me. Currently I use the Cisco for work (service is turned off unless I need it).
Wireless adapter disconnected, will blow it away. can't speak to the 'deterministic....'. I'll take care of the video drivers and report back

video driver swept and installed. TDSSKiller didn't find anything. I have removed the wireless network adapter and software. I have updated the Realtek network adapter driver. Cisco is turned off I only use it for work. I'll see if there is a newer version. the 'Deterministic...' doesn't show up in device manager so perhaps that went away with something else.

We'll see how it goes, I guess. Thanks again.

No BSODs after I updated the Realtek driver, was good all last night and this AM. Still monitoring.
Yes, I am geek

So far, so good.

 

[Arc]

Nice to know, mate

spoke too soon. 1 Kaboom this morning. Dump attached.

First of all, you are not running the driver version that I have suggested you earlier.

 lmvm nvlddmkm
  start             end                 module name
  fffff880`0f2a0000 fffff880`0ff94000   nvlddmkm T (no symbols)

Other than it is a known stable driver on which it is crashed, we cannot discriminate between hardware and software related BSODs.

And, it is overclocked.

 CPUID:        "Intel(R) Core(TM)2 Quad CPU    Q9505  @ 2.83GHz"
  MaxSpeed:     2830
  CurrentSpeed: [COLOR=red]2840 [/COLOR]

Get rid of the overclocks.

After strictly applying these two changes, if it still crashes, we may think it as a hardware related crash.

Hey Arc,
If you're referring to the video driver, I was on the 306.97 driver initially and I reverted to the 306.23 as you suggested. I have not deliberately overclocked my CPU. I did change some RAM voltages a couple of months ago the last time I was on a BSOD hunt (I think you chimed in on that one to). The last time this happened we narrowed it down to either the PSU (voltage fluctuations) or the motherboard. I really only posted this thread to see if it became more obvious whether it was one or the other. I'm going to mark the thread as solved and buy a new PSU after the holidays. Thanks for your help, as always.

Best of luck, mate. Make one thing sure that your power supply is adequate to run the new GPU. I cannot check it, but it is needed.
