Hi,

I've been having periodically errors (BSOD) for quite some time, and I am having a hard time figuring out where the error lies.

I've run substantial memory tests, I've updated drivers, bios update and I've run out of options.
I log my temperatures, and nothing is above normal. The bsod's are during games and during idle-time equally frequent.

I really don't know what else could be the problem. All of the hardware is fairly new (within a year) and I don't suspect the hardware to be faulty, however I am not an expert.
The hardware is not overclocked. My system specs are:


OS Name Microsoft Windows 7 Professional
Version 6.1.7600 Build 7600
Other OS Description Not Available
OS Manufacturer Microsoft Corporation
System Manufacturer System manufacturer
System Model System Product Name
System Type x64-based PC
Processor Intel® Core™ i7 CPU 860 @ 2.80GHz, 2801 Mhz, 4 Core(s), 8 Logical Processor(s)
BIOS Version/Date American Megatrends Inc. 1807, 23-07-2010
SMBIOS Version 2.6
Windows Directory C:\Windows
System Directory C:\Windows\system32
Boot Device \Device\HarddiskVolume1
Hardware Abstraction Layer Version = "6.1.7600.16385"
Installed Physical Memory (RAM) 4,00 GB
Total Physical Memory 4,00 GB
Available Physical Memory 2,07 GB
Total Virtual Memory 7,99 GB
Available Virtual Memory 5,57 GB
Page File Space 4,00 GB
Page File C:\pagefile.sys

GPU Radeon 5870 HD
catalyst 10.11

My windows is updated regular and there's no new updates

What can I do?

EDIT: Saved the new dumps in the reply

Download BlueScreenView:
http://www.nirsoft.net/utils/blue_screen_view.html
unzip downloaded file and double click on BlueScreenView.exe to run the program.
when scanning is done, go to EDIT - Select All
Go to FILE - SAVE Selected Items, and save the report as BSOD.txt
Open BSOD.txt in Notepad, copy all of the content, and paste it into your next reply

Oh, and you can delete that upload from your first post if you like. It's really not helpful and it affects the loading of this page. Thanks.

Multiple and varied blue screen errors generally point to a serious hardware issue. If you recently installed new memory, remove it and see if the problem persists. And you said much of the hardware is new - was something installed just before the problem appeared? I know you said you've done much of this already, but still - these are the troubleshooting steps I would take if Iwere you (in this order):

1) Download and run memtest to check the ram (http://www.memtest.org/). If ram passes with no errors then
2) Open an elevated command prompt (right-click on command prompt icon & open as administrator). Type: chkdks /r (then press ENTER). Say yes when asked if you want to run checkdisk at the next boot. Exit the command prompt and reboot. If hd passes with no errors then
3) Download and install the latest drivers for video and sound cards and check for a bios update. Get the drivers from the OEM websites, not from Windows Update.

If there is still a problem you may have a bad motherboard.

Please post back with results.

Did a memtest and a chkdsk with no faults, also did a cpu test using intels cpu tester with a pass.
Also did the bios update along with fetching new drivers for everything possible.

Edit: got the drivers from the manufacturers webpage.

If the fault is the motherboard how can i possible check that?

But in the end, if nothing shows up as being a problem you may just have to take a shot and replace the mobo. I've done it several times and it really isn't a big deal (other than cpu removal and replacement, which just needs to be done carefully).

Oh - and please - maybe you should remove the bsod report from your post above. It's causing the page to load VERY slowly. Thanks.

Update: It appears I found the error. I used Memtest86 for checking the motherboard, and it also checks the RAM. The RAM checker that comes with windows is definitely not suitable for checking the RAM. Memtest86 found a faulty when doing Moving Inversions, ones&zeros, although the RAM passed the other tests. So it appears the error was in fact my RAM module 2. I tested each of them separately and one passed with flying colours, while the bad RAM module failed on this specific test. I still have warranty on this RAM so I guess it's just a matter of replacing it. Note to self: Always do extensively RAM test when purchasing RAM, since this error has been here ever since I bought it.

Thanks for your help Allan!

Unfortunately this didn't appear to solve the problem. In fact the same bsod appeared:

If it's not the RAM or the motherboard, what could be causing this? I ran ubuntu on a live CD and it ran for hours without a crash. Could a fresh format help this kind of problem? Or did ubuntu just not use the same resources that windows does (thereby not using the faulty hardware). Now I'm puzzled if the RAM is bad at all, since it's been running on 4GB all this time with the same bsod's.

Update:

I appear to have found (for now) the solution, and have effectively stopped having BSOD's for 5 hours straight now (compared to once every 10-120 minutes).
I found a special case where Windows 7 64-bit had a problem with UDP traffic-filtering (Such as Zonealarm etc.), causing Unexpected_kernel_mode_trap with arg 0x8 (EXCEPTION_DOUBLE_FAULT). A windows special HotFix should help with this special case and can be found at http://support.microsoft.com/kb/981180/en-us.

The post that led me there can be found here: http://social.technet.microsoft.com/Forums/en-US/w7itprogeneral/thread/6a22ee15-634a-45d3-88a2-55c60c9a792d

As a side note, I have also terminated Zonelabs for now and if I don't recieve any BSOD, then by tomorrow I will try turning it back on and see if the HotFix did in fact fix the problem (if the BSOD returns, naturally I will reconsider using Zonelabs with win 7 64-bit).

Thanks for help, and I hope that This will help anyone else in this related problem.
