I started having BSOD issues (pardon the expression) out of the blue about a week ago. No major system changes that I can think of preceding it. Started by doing a full system scan with Panda, then MS Malicious Software Removal Tool, then uninstalled Panda and went to MSE. MSE found one issue---a Java based Trojan downloader---that I fixed, but the BSOD problem remained.
Just before the BSODs started, I had noticed a couple of issues. First, I could not connect any Bluetooth devices (MediaLink BT4.0 USB dongle), which I had never had a problem with before; I could remove and pair BT devices, but never connect to them. I don't really have any other USB peripherals, so I can't tell if it is a BT specific issue or a generic USB issue. The Webcam (integrated, though I assume USB based) works.
Next, I started getting the 'hardware disconnect' sound occasionally. Looking at Device Manager and ProcExp did not show any activity that coincides with the sounds, so I can't tell what it thinks it is disconnecting.
I looked through Dev Manager, including non-PNP devices. The only yellow was a missing WinPCap driver (nfp.sys); fixed that and still nothing changed. I ran memtest; in the first 8 hours, no issues, then when I checked again at about 20 hours it showed 2 errors. Nonetheless, I am not seeing the sorts of random system issues I would expect from memory issues.
Finally I installed WinDbg and started looking at the dumps. I set up the env variable for the Symbol Server, but all I get is:

*** WARNING: Unable to verify timestamp for win32k.sys
*** ERROR: Module load completed but symbols could not be loaded for win32k.sys
Probably caused by : memory_corruption
Followup: memory_corruption
So, all of that done, I still have a broken computer and no idea why. Help, please!
- Asus A53SD Laptop
- Windows 7 Home Premium SP1 (64 bit)
- OEM, original install.
- Don't actually remember how old the system is—2 years or so?
- Intel i7-2670QM CPU
- Dual GPUs, Intel and nVidia.
I could
not get 'perfmon /report' to run. The window shows:
Code:
| Error:
| | |
| An error occured while attempting to generate the report. | |
| The Data Collector Set or one of its dependencies is already in use. | |
BSOD collection attached. Driver Verifier is running now and I don't plan on sleeping or powering down the laptop, so we'll see if it finds anything.
Thank you!
