Basically i bought one of the affected mother boards before the b3 revision for sandy bridge systems. I managed to get an updated mobo via RMA.

So i changed mother boards over. Then a few weeks later i changed my RAM, old was Corsair XMS 1600mhz 4gb, new is Corsair Vengeance 1866mhz 8gb.

I also started off with a F60 Corsair ssd 60gb and change dthat to a new force 3 120gb ssd.



Since i reinstalled my OS (win 7 x64) i keep getting BSOD's. I have formatted and reinstalled and the same happens.

Please any assistance would be greatly appreciated...

Attached my minidump folder...

Thanks in advance.

Easy, these were related to your C-media Audio driver. I would update to the newest version below.

C-Media Electronics, Inc.




Since pool corruption was involved I would run these two tests.


1-Memtest.

*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program.

*Boot from the CD, and leave it running for at least 6 or 8 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

RAM - Test with Memtest86+

2-Driver verifier

Quote:

I'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Windows 7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

Driver Verifier - Enable and Disable

Hi,

Wow that was quick...

Ok i did the mem86 test and all was fine.

I forgot the c media stuff, that i THINK was from earlier BSOD's that i resolved to do with my new headset. The last 3 i have had are the ones i put in my OP some thing to do with NT Kernal ?

So should i still try the 2nd idea you gave ?

Thanks.

A few hours ago I started getting the same error on the same memory addresses. I have a suspicion that this is related to Sandboxie. You use this program?

Sorry for my English =)

Hi,

No never heard of that program... Sorry..

Hi again,

Ok so i did the verifier how you explained and got a BSOD on start up.

So i booted into safe mode and turned verifier off and here's the mini dump....

There should be 2 but the later one is the correct one, the first was me testing the verifier so i knew how to disable it

Ah i so hope someone can get to the bottom of this for me i will let you borrow my GF if you can lol

Hi....

Im assuming that last mindump i attached did not help ??

Anything else i can try please ?

The most recent two driver verified crashes were releate to HIDCLASS.sys (an OS file related to "human Interface devices". Things like fingerprint readers, accellerometers, etc)

Since this is an OS driver and you have updated to SP-1 I would run a systm file check to verify and repair your system drivers

Run a system file check to verify and repair your system files.
To do this type cmd in search, then right click to run as administrator, then
SFC /SCANNOW

Read here for more information SFC /SCANNOW Command - System File Checker

Let us know the results from the report at the end.

Hmmm...

All i have plugged in that i use is a mouse and keyboard and a headset...

I did the check and it says all is ok..

Incidentally i have not experienced a BSOD for 2 days now and i have been using my system just as i always do...

Well at least SFC didnt report any errors. Upload any DMP's if they occur.
