Helping people with computers... one answer at a time.

The blue screen of death can happen for many reasons, usually hardware failure of software bugs. Issues with web sites, however, is not one of them.

My wife has recently been intermittently experiencing the blue screen of death while on MySpace. It also wipes out the bookmarks in Firefox. I have always kept her machine lean and mean and up to date. It has current drivers, only four background programs and five non-Microsoft tasks running. Two separate Dell diagnostic programs give the hardware (one year old) a good bill of health. I have recently read that MySpace is using MS server software that is running out of expansion capabilities, and they are in fact having difficulties. Can a web site with the right combination of problems result in a BSOD or can that only occur locally within the PC due to a local problem?

Whatever problems MySpace may or may not be having, causing your "blue screen of death" (BSOD) isn't one of them.

A BSOD should never happen, but when it happens it always indicates a problem happening on your machine.

The dreaded "blue screen of death", or BSOD, appears when Windows determines that a very serious error has happened, and it can either no longer continue running safely, or it's become so "confused" about what it should be doing that it can't continue.

Windows XP Blue Screen of Death

Typically whatever you were doing at the time the error happens is lost, and your only recourse is to reboot your machine.

A BSOD "should" never happen. Windows is actually architected to handle errors in much more graceful and less abrupt ways. If a program does something wrong, for example, only that program should be affected; Windows, and your machine, should keep running without a problem.

But there are two common places where Windows simply cannot protect itself enough, and thus must rely on the last-resort BSOD to report errors:

  • Hardware failures - most commonly power supply, memory or motherboard problems. When memory fails or when a power supply is on the verge of failing completely not only can Windows get totally confused about what it should be doing, but it can also end up trying to do things that it simply cannot or should not do.

  • Device driver bugs - in particular kernel level device drivers. You probably won't be able to tell which is which, but some device drivers operate at the same level of privilege as Windows itself. A bug in such a driver can result in a BSOD. (Some drivers can operate at the same privilege level as applications under Windows, so if they have a failure they may crash, or an application may crash, but a BSOD is infrequent.)

"A BSOD 'should' never happen. Windows is actually architected to handle errors in much more graceful and less abrupt ways."

There are other issues that can cause a BSOD, including bugs in Windows itself, but those BSOD bugs are very infrequent these days.

Note that there's nothing in the previous discussion about websites or the internet. A BSOD is something that happens on your machine, because of a problem with your machine or the software on it. If you regularly experience a BSOD when you visit a particular web site, then that web site isn't directly causing a problem, it's simply causing your computer to exercise some software or hardware on the machine that has the problem.

So what do you do?

Well, to start with it sounds like you've been doing the right things:

  • Keep up to date with the latest critical fixes from Microsoft.

  • Keep up to date with the latest driver updates, either by visiting Windows Update, the hardware manufacturer's site, or preferably both. (Updates can often be found on one or the other, but not always both.)

  • Run hardware diagnostics.

The BSOD looks like a bunch of gobbledygook to most folks, but there's often an important clue or two in the mess. For example:

Specific Error Message on a BSOD

In this example, the BSOD is actually pointing at a specific file that may be related to the error. If it's the same file every time, then that suggests a software or driver issue. Figuring out what that file does (often a quick Google search will do), may lead you to the driver in question. If not the software, then it may indicate a problem with the hardware that driver controls.

Unfortunately it's only a clue, not an answer. The file may be totally unrelated to the problem.

Often diagnostics that come with computers aren't quite as thorough as we might like. There are two tools in particular that I would suggest, depending on your situation:

  • Memtest86 - a very thorough memory testing utility. There's been a slow increase in problems with memory, and this tool should ferret out if you have a problem, and exactly where. Memtest86 is free.

  • SpinRite - an extremely thorough hard disk testing and recovery utility. SpinRite is not free, but it's the most exhaustive hard disk testing and recover utility I know of. If your problem is due to bad sectors on your hard disk (which could result, for example, in a corrupt copy of Windows or its drivers), there's a fair chance that SpinRite won't just tell you about the problem - it'll fix it.

BSODs can be very difficult to track down. In many ways it boils down to detective work, and I hope that with some of the information above you'll be able to get a few clues as to what's going on with your machine.

There is a good chance that the bookmarks are MIA rather then wiped out.

I have had a few BSOD's but in each case the blue screen has come up & gone that fast it is impossible to read, much less take down the details. The system then shuts down & restarts.
How do I make it slow down.

Re: Blue Screen of Death

I got those a lot; couldn't figure out the problem! Finally hard drive went bad without any other warning; laptop on warranty and hard drive replaced--computer great now.

For Brian -- To stop your computer from rebooting automatically after a BSOD happens, do the following: Right click on My Computer and choose Properties; click the Advanced Tab; under Startup and Recovery, click the Settings button; then under System Failure, uncheck Automatic Restart (I'm doing this from memory, hopefully it's correct. If not, post again and I'll go and look at my XP machine - I'm on Vista right now).

This might seem stupid, but the problem might exist _because_ you have all new programs, not _despite_ it. New programs are prone to higher hardware resource usage. If, together with that, your wife opens a flashy, cool website, the hardware gets even more worked out. The result is a simple overheating, which makes the system go crazy.
Dusting and vacuum cleaning the insides of your computer might help, though...

my pc have blue screen of death.Can my computer die?

April 10, 2008 8:25 PM

I had the same exact problem with my 3 month old HP with Vista Home Premium. The problem turned out to be the virtual memory settings. It's an easy fix, just increase the size of your virtual memory.
My new computer wasnt even set to the recommended settings; once I re-set it I had no problems.
Start>Computer>System Properties>Advanced System Settings>
Youll need permission to go on, click continue...
Click Settings in Performance...
Click Advanced...
Click Change...
Click the custom size radio button...
I set initial size to 2300 MB or (300 over your amount of RAM),
I set maximum to 6000 MB or about (3 X your amount of Ram).

That should do it.

I used Ji,'s advice, and it may have worked. I saw that the minimum VM was set to 16, and the max was set to a little over 2,300. The recommended was over 3,000. I did as suggested, and changed the minumum to 2,300 and the max to 6,000. I sure hope this works, and if it doesn't I'd need immediate help, before resorting to a new hard drive, etc. Thank you for your help so far. :D

hi there Leo,

my laptop has also been getting the BSOD,

and only ever while on MySpace.

Could it be that one has to save your

input into the Blog often?

(I know you said that it could not

be MySpace, but I wonder).

Yours sincerely

I know for a fact that windows 98SE crashes when you access con\con so if the following code is put into the webpage: [img src=\con\con]windows 98 se crashes!

Sorry to burst your bubble. I was researching the terrible lyrics used by rapper B.O.B. and when I go to his website, my computer gets a BSOD, "every single time" without exception. Not happening anywhere else, just his website and it happens immediately as firefox is loading the page after I click the link from the google search page.

My bubble's intact. It's only software on your machine that can cause a BSOD. There's something about that site that is causing software on you machine to misbehave. It all comes back to software on your machine - be it malware, the browser, addons in the browser or what not.
