I receive a BSOD error after running my pc for 12+ without a shutdown or restart. I've tried all I can to find out what is causing this with the information within the following minidump, and all I could figure out is that it might be linked to fastfat.sys, and that the callstack is messing with volumes, and maybe I/O as in in out? I don't know... The name of that .sys file reminds me of when I reformatted this HD I used the fast reformat option available. Hopefully someone can help me figure out what is causing this recurring BSOD.

Other relevant info: Recently installed Windows 7 32bit over a previous OS; Recent Nvidia 8600 GT installed (due to the minidump and google searching doesn't seem to be graphics card related, at least from what I can tell). I just finished running memtest for a couple hours and 0 errors were found.

Code

UNEXPECTED_KERNEL_MODE_TRAP (7f)
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
Else
.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)
Endif
kb will then show the corrected stack.
Arguments:
Arg1: 0000000d, EXCEPTION_GP_FAULT

Anyone around here any good with BSOD debugging? Or at least better than I am? Let me know if any other info would be helpful, and thanks for any help.

To recap our shoutbox discussion;

If that M$ hotfix doesn't fix anything, all of the information I am finding so far in relation to this error points to hardware failure (especially memory). But since your memory is supposedly fine, I am wondering if there is indeed some nature of software-related aidsy going on. Anything that could be donkeying around with the memory when it shouldn't be and all that nature.

Since we clarified that your OS is actually a fresh install and not installed over something else, that rules out potential conflicts of some nature.

Since you stated that you have run very system intensive processes for a long period of time without issues before that rules out (to me at least) potential issues with the GPU and heat.

Information I find relating to that sys file suggests that it is related to USB devices (in windows XP anyways) and another says it's related to RAID or somesuch. It definitely has something to do with drives/partitions in some way. Though the name insinuates that enough on its own. If you are running USB devices, especially old ones, perhaps consider disconnecting them and trying it then? I don't know. Just throwing ideas here.

I/O related stuff reminds me of issues I had with PCI devices... are you using a PCI-based network port? If not, do you have one available that you can use instead of the mobo?

Show them your butt, and when you do, slap it so it creates a sound akin to a chorus of screaming spider monkeys flogging a chime with cacti. Only then can you find your destiny at the tip of the shaft.

This is what google sent me to. According to this you either need a micro update for your processor (article has further details) or is damaged, or run out of spec (heat, current, voltage, etc.)

The fastfat.sys has something to do with converting file systems afaik. FAT is an old file system that's been replaced by NTFS for hard drives, but is still used on floppys and USB sticks.
Anyways, since the error is only occurring after extended system uptime I'd suspect a job is running in the background. This could be the virus scanner checking your drives, or a defrag program, or a windows service like the index service. Try to find and disable any of these background services.

Another google hit was a resolved topic about the same error, but on Win7. In that case it was caused by the Zone Alarm firewall, increasing my suspicion against virus scanners and other software that works deep in your system.

Does it "reset the 12h+ counter" if you put your computer in sleep mode before the error can happen?
Also you could try starting up in safe mode and see if it "fixes" it. This is mainly to get a better idea of what could be causing it.

Put the minidump into a zip and post it over at the windows seven forums. They usually respond within 12 hours and tell you definitively what's causing the problem, how to troubleshoot and make sure it is that, and then what to do to fix it.

Also, memtest for a couple hours is no use. Run it over night - but I don't think your problem is caused by memory if it is as you say, occuring after a long period of system uptime (as opposed to entirely randomly as it would be were it caused by memory).

None.

Figured out it was a failing RAM stick after some more BSODs occurred with different error messages.

Does this mean you'll be able to host your terraria server a lot more often now that you've fixed it? :awesome:

I haven't fixed it yet, but yes
