Windows 7: Newly Built System - Windows 7 BSOD.

09 Sep 2009   #11

Windows 7 Ultimate x64

Have a look at this information, from the Microsoft Developer Network that describes what STOP 0x7F means: Bug Check 0x7F: UNEXPECTED_KERNEL_MODE_TRAP.

The first parameter of the bug check in your case is 0x00000008, which means the following:

0x00000008, or Double Fault, indicates that an exception occurs during a call to the handler for a prior exception. Typically, the two exceptions are handled serially. However, there are several exceptions that cannot be handled serially, and in this situation the processor signals a double fault. There are two common causes of a double fault:
  • A kernel stack overflow. This overflow occurs when a guard page is hit, and the kernel tries to push a trap frame. Because there is no stack left, a stack overflow results, causing the double fault. If you think this overview has occurred, use the !thread debugger extension to determine the stack limits, and then use the kb (Display Stack Backtrace) debugger command with a large parameter (for example, kb 100) to display the full stack.
  • A hardware problem.
Go through the rest of the information on the MSDN website. It may help isolate what is causing this error.

On a related note, I've seen STOP 0x7F numerous times on computers where users have installed BETA drivers, or incompatible "Virtual CD/DVD" drivers. If this is your case, try uninstalling the program, and then locate and install an updated (7-compatible) version.

Ugh a hardware issue? Well isn't that just great to know....hmmm, is there a possible way to tell what part might be causing the issue? I am thinking either the cpu or the gpu can be faulty?

Remove all "additional" hardware you may have installed, including your graphics card (unless your motherboard is not equipped with an onboard gpu).

Overheating or incorrect overclocking can also cause "hardware issues"...

I've just had a look at the motherboard manual. There is no on-board graphics, so check which slot you have inserted your graphics card in. It should be in the first slot, nearest the CPU.

After a q2quick look at the dump file the bsod was caused by netIO.sys there isnt a whole lot of info on the reason netio failed but I would try disconnecting any hware that isnt critical like external usb HD, etc. I would also look at the date on netio.sys file to make sure it is current. you can search for it. When one of our true debugging gurus look at the dubegging info they may be able to give you more info.

This means a trap occurred in kernel mode, and it's a trap of a kind
that the kernel isn't allowed to have/catch (bound trap) or that
is always instant death (double fault). The first number in the
bugcheck params is the number of the trap (8 = double fault, etc)
Consult an Intel x86 family manual to learn more about what these
traps are. Here is a *portion* of those codes:
If kv shows a taskGate
use .tss on the part before the colon, then kv.
Else if kv shows a trapframe
use .trap on that value
.trap on the appropriate frame will show where the trap was taken
(on x86, this will be the ebp that goes with the procedure KiTrap)
kb will then show the corrected stack.

Check to see if your memory is getting the right amount of volts in your bios, most memory is either 1.8v or 2.0v

Good Luck

Windows 7 Professional

Hey, guys thanks for all of the information and tips. I have reinstalled the Drivers on my ATI card and left it running on all night (acutally I went to throw in my old nvidia card which I have running on my vista machine, and realized I did not fully uninstall my ati drivers and just tossed the ati card back in), have not got any BSOD's as of yet. I have been looking up on the netIO.sys file and it seems to be some kinda of network driver? My motherboard has 2 ethernet ports. I have net cables plugged into both of them. Do you thinkg that can be casuing an issue?

I have not looked at the netio.sys file as of yet, when I get the time to look at it, what exactly am I looking for? Since it is a .sys file how am I going to open it to check the date as Ken mentioned? Also, can external usb devices like a mouse or keyboard drivers cause this problem or is this error message always related to a hardware problem rather than a incompatible driver? Thanks.

Just an update for you guys. I did some more reading on that NetIO.Sys and it seems to relate to the network adapter? So I went into my device manager and updated the drivers on that. Windows actually found new drivers for it and so far no BSOD. So I am hoping that everything is ok.

However, if anyone else cares to look at the dmp file that I posted and give me more suggestions I would appreciate the feedback. Thanks!
