Windows 7: BSOD ntoskrnl.exe (nt+0x7CC40) - 0xA

21 Feb 2012   #1

Windows 7 Professional x64
BSOD ntoskrnl.exe (nt+0x7CC40) - 0xA

I am experienceing the BSOD very often. More than 15 - 20 times a day.
Before coming to this site I had already deleted all the files in C:\Windows\minidump to do a clean troubleshooting.
Then when I got the BSOD the first time I used the tool to dump everything.

I have attached the dmp and perfmon report.

Following is a report from WhoCrashed

This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver which cannot be identified at this time.

A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: rt64win7.sys (Realtek 8101E/8168/8169 NDIS 6.20 64-bit Driver , Realtek Corporation ).

An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.

Caused by Rt64win7.sys which is your Realtek RTL8168D/8111D Family PCI-E Gigabit Ethernet NIC and should be updated from Realtek .

What Sony VAIO model do you have so I can help you update the important drivers listed as outdated?

SFEP.sys is a big one (and you probably won't find the update for your model through your model's support page). Your wireless and graphics card drivers also need to be updated.
