BSOD: Unexpected Kernel Mode Trap - 0X1000007f

Hey Guys,

I am new to the forum & this is my first post here... I need help!

Yesterday for the first time I got a BSOD & I was not able to read anything it just restarted, then everything looked alright.

Today again I got the same BSOD, after the restart i looked a bit into it and was able to read the dump file... but didn't understood anything

The minidump file is attached in the post.

I hope you guys will help me solve this problem!

Thanks :)

Did it generate a single .dmp file only? Not any other text files and one .nfo file?

Usual causes:
Memory corruption, Hardware (memory in particular), Overclocking failure, Installing a faulty or mismatched hardware (especially memory) or a failure after installing it, 3rd party firewall, Device drivers, SCSI/network/BIOS updates needed, Improperly seated cards, Incompatible storage devices, Overclocking, Virus scanner, Backup tool, Bad motherboard, Missing Service Pack

Install Service pack 1 and all other windows updates. Otherwise the system will remain vulnerable to threats.

Are you overclocking? As you are getting BSODs, you should stop overclocking and run all the hardware components like CPU, GPU and RAM to their default settings. Also set the BIOS to default, too.

You use NVIDIA nForce Serial ATA Controller (SCSI) which is very old.

But no updates are available at ASUSTeK Computer Inc. -Support- Drivers and Download M2N68-AM SE2 . You may try it in nvidia. Go to Drivers - Download NVIDIA Drivers, search for nForce, as per your motherboard's chipset specifications.

At the same time, if it is possible, plan to update the BIOS. Your BIOS is old, too.

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.
