NETIO.SYS SYSTEM_THREAD_EXCEPTION_NOT_HANDLED BSOD while broswing

I received a BSOD this evening and have tried to investigate the error on my own, but would like to ask for some more experienced help on confirming or debunking my hypothesis on the actual problem.

Attached are the minidump files and the system performance reports.

While looking at the mini dump file, the first analysis states:

BugCheck 1000007E, {ffffffffc0000005, fffff800030ab4f0, fffff88003762928, fffff88003762180}
Probably caused by : NETIO.SYS ( NETIO!FreeSomeCacheBucketEntries+61 )
Followup: MachineOwner

However a little lower I see this:

EXCEPTION_CODE: (NTSTATUS) 0xc0000005 - The instruction at 0x%08lx referenced memory at 0x%08lx. The memory could not be %s.

My thinking is that the memory actually failed which caused the NETIO.sys to fail as it was attempting to read something in memory at 0x%08lx but because of the % the system crashed.

So the solution is more a result of bad memory than it is of a system failure? or is it the opposite?

Thank you in advance for helping a novice figure out what is wrong.

These were indeed memory exceptions (Cx05) and in one case it was netio.sys that failed. Often when netio.sys has failed it is as a result of the installed malware app. Norton is known to cause these on some systems.

Symantec is a frequent cause of BSOD's. I would remove and replace it with Microsoft Security Essentials AT LEAST TO TEST

How To Find Drivers:

- search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.

- - Driver manufacturer links are on this page: Drivers and Downloads


Please remove any CD visualization programs such as Daemon Tools and Alcohol 120%.

They use a driver, found in your dmp, called sptd.sys, that is notorious for causing BSODs.
