Windows 7: BSOD when system sitting idle

BSOD when system sitting idle

I have a Dell E6500 running Windows 7 Professional, 64-bit system. It's been running fine for months, but suddenly within the last 48 hours I've had three BSOD's, all when the system was sitting idle. (Programs active on the screen, but I wasn't physically using the system when the crashes happen.)

I spoke with Dell tech support on the phone, and we ran the built-in diagnostics on the system, and all the diagnostics pass.

I haven't installed any new hardware/drivers/whatever recently, although I can't speak for anything Windows Update might have done to my system. (Nothing obvious based on looking at restore points in System Restore.)

The three faults seem to be the same:

Probably caused by : ntoskrnl.exe ( nt+71f00 )

*******************************************************************************

* Bugcheck Analysis *
* *
*******************************************************************************
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: 0000000000000008, EXCEPTION_DOUBLE_FAULT
Arg2: 0000000080050031
Arg3: 00000000000406f8
Arg4: fffff80002a52798

Any help would obviously be greatly appreciated. I'm really hoping I don't have to melt this machine down - it's only 3 months old...

Welcome!

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

I suggest a hard drive and memory test.

Hard Drive Diagnostics Tools and Utilities (Storage) - TACKtech Corp.

Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder.. Boot from the CD, and run at least 5 passes.

Also run a system files check: Open an elevated command prompt and enter sfc /scannow.

Also, what anti-virus are you using? Could it be scanning in the background as soon as it detects that the computer is idle?
