Windows 7: Crash for no reason??

Crash for no reason??

Hi all,

Playing a flash game from (sad I know) then win 7 crashes for no apparent reason. I've attached the dump file. Thought I was getting some stability out of this system, but not quite. No over-clocking btw.

Attachment 93614

Thanks for taking a look see.

Hi John, I will take a look and be right back.

Error code 7F, UNEXPECTED_KERNEL_MODE_TRAP - usually caused by Memory corruption, Hardware (memory in particular), 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

Are you overclocking? If so please return all to default values.

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.

The dump does not point to anything specifically. Let's start by testings your RAM. Read through this thread and folow those instructions. Errors, if any, will be displayed in red. Post back with your results.

RAM - Test with Memtest86+

Please uninstall Zone Alarm. Zone Alarm is a known cause of BSOD's on most Win 7 systems. Turn on Windows Firewall in its place. What antivirus are you running? If it is Kaspersky or any third party antivirus, uninstall it while you are troubleshooting. Replace it with Microsoft Security Essentials. Many third party antivirus programs cause BSOD's on some Win 7 systems. Our objective here to remove known causes of BSOD's. Once you get your system running smoothly, you can install a third party antivirus and try it. However, I do not recommend doing so.

I find some outdated drivers on your system. Generally speaking, Win 7 does like drivers dated prior to July 13, 2009. Obsolete drivers can cause memory corruption and crashes.
AsUpIO.sys Sun Jul 05 22:21:38 2009
PxHlpa64.sys Tue Jun 23 19:16:35 2009
wacommousefilter.sys Fri Feb 16 13:12:17 2007
Update these three drivers. That 2007 driver coupled with ZA is sure to cause problems. If you cannot update that mouse driver, I recommend you upgrade your mouse to one that is certified compatible with Win 7.

How To Find Drivers:
- I have listed links to most of the drivers in the code box below. Please use the links there to see what info I've found about those drivers.
- search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.

- - The most common drivers are listed on this page: Driver Reference
- - Driver manufacturer links are on this page: Drivers and Downloads
If you need help with the drivers, please post back.

After you do the above. Reboot and run your system. See how it runs. If you get another BSOD, upload it and we will go from there.

The mem test is green, no errors.

I was surprised to see such an old driver for the wacom pen tablet, particularly as I thought I had updated it a few weeks ago. I'll check it + those others mentioned.

Cant find a later version of this driver: wacommousefilter.sys Fri Feb 16 13:12:17 2007

Checked the Wacom site, and as far as I can tell, that is the latest version. Seems a tad old. Am I looking in the right place?
