0x0000007f (UNEXPECTED_KERNEL_MODE_TRAP)

[AceCombat]

im getting this almost daily..... damaged hardware or corrupted software?


Nirsoft's BSV is telling me everytime its either one of the following:

iaStor.sys or ntoskrnl.sys



also, the parameter1 according to this: http://support.microsoft.com/kb/137539

is telling me 00000008

which is saying Double Fault... or


Double fault
A double fault occurs when an exception occurs while trying to call the handler for a prior exception. Normally, the two exceptions can be handled serially, however there are several exceptions that cannot be handled serially and in this situation the processor signals a double fault. The two primary causes for this are hardware and kernel stack overflows. Hardware problems are usually related to CPU, RAM, or bus. Kernel stack overflows are almost always caused by faulty kernel-mode drivers.



can someone elaborate on this and why is it doing it almost daily now

you have a software raid setup?

there was a recent Intel Raid Matrix driver on Windows update just a few days ago!

Use system Internals and disable IAStore from running during Bootup.. Unless you have raid

[AceCombat]

neg on the RAID, all drives are independent


so uninstall Intel Matrix Technology?




while im thinking about it, i did have a slight OC on the CPU which is supposed to be a 100x39 ratio, i had pushed to 100x45. i did read in a couple of places that an applied OC can sometimes trigger this BSOD BCCode.

i just uninstalled Matrix Tech. and relaxed my OC back to a 100x40 ratio

Thoughts?

I said Disable, not uninstall... check injuries first before cutting off limbs

"Use " system Internals " and disable IAStore from running during Bootup.. Unless you have raid"

http://technet.microsoft.com/en-us/sysinternals

Download the whole package SystemInternals and copy the folder to Program Files

use autoruns (not autorunsc)

[AceCombat]

my bad, re-installed and disabled IAStor

[AceCombat]

welp, i got another one, came home from work.......... 0x0000007F (UNEXPECTED_KERNEL_MODE_TRAP) IAStor.sys



yet, i disabled iastor.sys from even running at boot?


did i miss something here?

How do you have your sata controller and raid controller configured on your motherboard?

Back to basics

If your not using raid the onboard raid controller should be disabled in the bios

[AceCombat]

ok layout:
Asus SABERTOOTH Z77 Board


i have 2 SATA III Drives on the Intel SATA 6GBps connectors, used independently of each other no RAID

1 SATA II Drive on a SATA II 3GBps Connector

and 2 Optical SATA I Burner Drives on two of the SATA II 3GBps Connectors

i have 4 3GBps and 2 6GBps Intel Z77 and 2 ASMedia ASM1061 SATA III 6GBps


i use all the Intel Connectors and none of the ASMedia ones

all the Intel Connectors are on AHCI Mode

Uninstall Intel rapid storage technology, which should kick you back to msachi.sys.

[AceCombat]

done

You might want to grab a copy of the as-ssd benchmark, it can show which ahci driver you are using. Just don't run it on a hard drive unless you have a couple hours to spare while the drive thrashes.
