Faulty hardware, including RAM (system, video, or L2 cache).
Caused by improperly configured jumpers on PATA hard drives, a boot sector virus, or incorrect IDE controller drives, which can also occur when installing the wrong chipset drivers.
Caused by installing the wrong drivers for a videocard or rebooting before driver installation could complete.
Caused by a faulty or incompatible hardware driver, particularly when upgrading Windows XP instead of performing a clean install.
Caused by faulty RAM.
A bad CPU -- or one that is too aggressively overclocked, or an underpowered or faluty power supply.
Reading blue screens of death is fun and all, but there's another, easier way to discover what your PC's problem is: the Event Viewer. When an error occurs in Windows, the OS adds a note to the system's log files. These logs are accessible through Windows's Event Viewer, and they contain all the information we need to know what ails our poor computer.
In XP, go the Start menu and open the Control Panel. Click Administrative Tools, then double-click the Event Viewer icon. Altternately, select Run from the Start menu and type eventvwr.msc, which will bring you right into the Event Viewer. In Vista, just type Event Viewer in the Start Search box.
On the left-hand pane, highlight the applicaton or system icon (under Windows Logs in Vista). On the right-hand pane, you'll see up to three different events labled Information, Warning, and Error. These are sorted by the time in which they occured. Scroll to the approximate time of the last system restart and double-click the events.
This brings up a Properties window detailing information that should clue you in on any problem. For example, if one of the events contains a bugcheck message with 0x0000002E, we know this is a DATA_BUS_ERROR, and is usually indicative of faulty RAM. On the other hand, there might be several events pointing to a specific driver, such as nv4_disp.dll. This tells us we should focus on the videocard and any recent changes related to the display hardware.
Armed with this information, we're ready to beging the troubleshooting steps outlined previously. If typing the event ID into Google and Microsoft's Knowledge Base (http://support.microsoft.com) doesn't help, head over to www.eventid.net. This site contains a repository of comments and errors from other users, as well as the steps they took to alleviate their problems.
We recommend you familiarize yourself with the event viewer, even if your system is healthy. Rooting out minor problems before they progress will ensure your Windows install keeps humming along uneventfully.

Always recommed a RAM or HD check with the BOD. Its rarely the motherboard unless your living in a hot country when the cooling fans aren't enough, especialy for multi core systems. cannabis seed

I installed Windows 7 over three months ago. MICROSOFT FINALLY GOT IT RIGHT!. I am thrilled with it!. That being said, this article says nothing about possible BSOD error messages for Windows 7(not that I might need any.)
Do any of these BSOD error messages relate to Windows 7.?
Please e-mail me, if anybody knows. lapter1@live.com

As a conclusion:
I upgraded Realtek driver for onboard
audio from Gigabyte support page
(http://www.gigabyte.com.tw/Support/Motherboard/Driver_Model.aspx?ProductID=3005&ost=xp#anchor_os)
and then re-enabled onboard audio.The PC runs OK and sound is OK too.
So, for GA-MA790FXT UD5P owners
encountering BSOD at login (XP SP3), I recommend the upgrade of
Realtek driver, in the case onboard sound is enabled.Thanks for the valuable information I
found here.Other valuable information found there:

Thanks for this guide.
I encountered a BSOD issue on a AMD/Gigabyte newly assembled PC running XP SP3.
Not every time, but often, BSOD occurred when attempting logging in when asked to. After a RAM verification by MemTest86, and a cleaning with HighjackThis and SmitfraudFix, issue appeared fixed but some days later, BSOD was there again.
As a file was often indicated (portcls.sys), I disabled onboard sound and now, the issue seems to be fixed.
Nevertheless, I'll try to upgrade mobo sound drivers and try then to enable onboard sound again, knowing that there is a backup solution.

I work in a computer repair store and we see this BSOD as often or more than all the others listed. Usually this is a result of a failing HDD or an interuption while the drive is being written to. A free utility call MHDD will scan the drive and tell you if there are slow or unreadable errors on the drive. If the scan passes, then run a chkdsk /r on the drive and usually it will fix the BSOD. If there are errors on the drive, it still may be able to be backed up depending on the amount of failed sectors. Don't use Ghost on a failing drive though, as Ghost will quit when it hits the unreadable sectors. Unstoppable Copier should be able to copy the data from that drive if its hooked up to another machine.

I deleted the last thing that I downloaded to my computer. And that worked fine for about 3 hours. now its back. And when it comes up the number thing is like 0x0000008 or something.

Hi. I'm new here.... I just have an unsolvable problem wonedered if anyone would have some advice....has anyone ever had the situation where the BSOD on a laptop running windows xp does not freeze, it just flashes very briefly and then immediately tries to reboot, but it can't reboot and simply goes to that screen that gives you multiple choice start up questions like: start windows normally, use last known good confiuguration etc.
whatever I choose it still can't boot up. tried to boot from windows cd to repair installation, but won't allow it only allows new installation. Would love to not lose data. Any one have any ideas?
Thanks.

Since there is a screen-save at the top of this article there must be a way to do it - or is it a photograph of the BSoD taken with a digital camera. Thanks, Phil

UNMOUNTABLE_BOOT_VOLUME is one I run into a lot as a tech... can mean bad sectors on a HDD (chkdsk if you're lucky), file system/partition/boot problems (OS config crapped out, recover data & reimage), but usually means a dead HDD.

Thx 4 allowing me 2 vent in subject line! I now have the BSoD problem I've never had b4 thx 2 a well dick thinking with same so what I desperately need help with is MY problem! Selfish? I don't care. I receive the error msg KERNEL_DATA_INPAGE_ERROR my 1st code being 0x0000007A of course I am unable to follow the advise 2 check if any new software is the cause I update my drivers and actually take good bloody care of my PC but I have no new hardware nor have I had a single problem until I left her alone with an obvious addict to porn and he exposed her to that seedy underside of PC's with a webcam then exposed himself to her as well! I've had it many yrs but bought out of box and whomever returned it made the system restore set of disks as I was unable tho created the system recovery disk. My computer no longer will go to Windows at all not even using my favorite option with F8-safe mode with command prompt. I LOVE DOS but it will NOT start at all except 2 perform the restore using that partitioned part of the hard drive I never got around 2 removing. 2 bad the system restore runs the course just 2 still not work then trying 2 start the restore again! Ive had 2 use recovery disks on HIS PC's several times 2 often but with success as it seemed 2 be as simple as when 1 has 2 fix the sndvol32.ex_ problem. But now Im clueless and unfortunately also on a very VERY low fixed income thx 2 too many surgeries on my rt shoulder so I simply do NOT have a single cent 2 spare and I have NO bils either. I do have what seems an unlimited amount of thieves who learned I am a sports fanatic somehow deciding 2 steal everything I own or die trying! Where did they come from? Someone ALMOST got my Mickey Mantle autographed baseball but did not. But 2nite some1 somehow stole every single CD I had left plus cases and damn it they also stole my vibrator! So getting another PC is not an option and I do EVERYTHING online since, well, since I invented the internet! Fine I just helped. PLEASE PLEASE help me and that is me hoping U can! Thx so much!

But there is definitely something far worse than linux and mac whiners...I tell you what:
A pc whiner posting in a website talking about how to fix windows BSOD...
Please have a look at the windows website and then look at mac os x website, you will be able to tell which one was done in a PC. Apple's website show the users how to use their system and what cool things they can do with it. The windows website suggest you buy and antivirus for your system.
Now troll me if you want, I will be playing games in Mac and probably I won't answer.
BTW Apple OS X have a dictionary and a spell/grammar checking tool integrated in the OS so you could type safe in a website (Firefox also has a spelling plug-in but that's another story), trolls!!

Excellent resource to have on hand. I can think of several people I can give this too.
- still there, but we're here to tell
On page 1, paragraph 7; should be "still there, we're here to tell".
- the most overclocked, but they can
On page 3, paragraph 2; pretty sure it should be "overlooked" not overclocked.
- you have a space cable lying around
Also on page 3, paragraph 2; pretty sure it should be "spare" not space.
- then look for an mark any bad sectors
On page 3, paragraph 3; should be "and".
- hard drives are connect to, so you'll
On page 3, paragraph 4; should be "connected"
- This utility stressed your rig's CPU
On page 3, paragraph 6; should be "stresses"

Grammar? Sure looked like he was correcting spelling errors (that happened to slip by the spell checker AND EDITOR).
Considering how poorly most web posters write, I think we need as many articles with proper grammar, spelling and syntax, as possible. Frankly, if people who write for a living can't get it write [sic] and the editor misses it as well, then maybe the publication needs a new editor and writer.

May 01, 2009 at 11:12am
Good guide, but it's missing a few common scenarios:
IRQL_NOT_LESS_OR_EQUAL can also be caused by memory errors. This is especially common if you've overclocked the RAM or tightened the timings too far.
PAGE_FAULT_IN_NONPAGED_AREA will almost certainly come up if you turn off all swap files. Sadly, some programs and drivers just can't handle it if there's no swap file.

I've just watched 1 very smart person waste the better part of a week getting Linux wireless to work on our network (never mind the peripheral players who spent hours of their time trying to help him).
In the end, he got it working, but he's not sure why it now works.
Until linux is truly plug and play, it's only for IT types, and as this week illustrated, even then it's not easy to set up....and several of those involved run Linux at home.

OH!, nm it won't run on Linux". Sure you can run X-Windows, but then, you're back to running Windows and put into the same possibiility of troubleshooting a BSOD. Besides, why run an emulator and suck up unnecessry resources in an emulator? Might as well just run Windows. Go troll elsewhere dude.....
Besides this article is long winded. Want to know how to REALLY troubleshoot a BSOD? Type the Hex code into Google, you'll have your answer and beging to be able to repair the problem from there.

May 01, 2009 at 3:13pm
Well, your comment is pretty clear about the fact you don't know a bit what you are talking about.
First of all, X-Window (notice, no s) isn't having anything to do with Windows. Just take a look at Wikipedia.
X-Window came to like in 1983 from the Carnegie-Mellon Andrew project while Windows 3.1 came to life in 1985, two years later. X-Window is built from start as a client-server graphical system on top of an OS, while Windows is an OS and not client-server at all.
Second, gaming is not all in life, most useful usage of a graphical system and a computer is not gaming, so, saying Linux is a piece of shit because your favorite game doesn't run natively on it is a very narrow biased evaluation of an OS as a whole.

M$ has a lot of issues, but I'll take a half ass informative BSoD in Windows over a zero informative screen/computer freeze in Linux any day.

I still duel boot Vista/Linux mint and Linux mint doe's not crash on me and my CPU/HDD do not constantly run in the background. I'll keep Linux mint over Vista. I duel boot so my Kid can use Vista.

1. Games are not for kids. Most PC gamers are in their 30's or older.
2. They want to play a game, not spend hours on research and configuration of an emulator.
Why do fanboys (of all the various OSs) seem to feel that EVERYONE should use their OS. I like windows, but if you're developing for *nix servers, *nix is probably a better OS to work with.
If you're doing music or video production, Macs are probably your best choice, in most cases.
If you're a general user who likes to play games, Windows is hands down the best platform. It makes no sense to use a Mac or Linux and Wine to play games.

For god's sake, it's an OS....a platform to run the things you actually bought the computer for.

I've seen Ubuntu crash more than once, so quit acting like it's this invincible OS that doesn't crash. Likewise, I rarely see windows crash. Which crashes more? Hard to say, because I'm on windows far more than Linux, so I'd expect to see windows crash more....the reality is that I might see windows become unstable once or 2x/year on my machines. I've seen linux (Ubuntu) crash once (maybe 2x) in the past year.
They're both good operating systems that serve very different markets and very different purposes.
