Why does my computer blue screen?

Summary: While there are many reasons your computer could blue screen, there are some things you can look into to help determine the cause.

I keep getting a "blue screen of death" and the following error message: PAGE_FAULT_IN_NONPAGED_AREA and a bunch of other lines and the computer locks up. What is causing this and how can I fix it?

Unfortunately with only that to go on, there are hundreds, if not thousands, of possible answers. To really diagnose, we'd need a lot more information about the system it's happening on, the software and hardware installed, and what was happening at the time the problem happened.

I'll throw out some guidelines, so perhaps you can narrow down the diagnosis.

  1. New Hardware - while the hardware can sometimes be bad, the real culprit is typically outdated, or just buggy, drivers. If you've just installed new hardware then it's likely to be related to the problem. Make sure you're running the latest drivers for that device that you can, and check with the manufacturer's support site for specific information. Conversely, if you've just updated drivers, that would also be something to be suspicious of.

  2. New Software - it's rare these days, but occasionally software can cause this as well. If you've just installed new software then I'd be very tempted to uninstall it and see if the problem goes away. I'd also make sure that your Windows is as up-to-date as possible by visiting Windows Update.

  3. Viruses and Malware - Since they're written specifically to cause damage, this is occasionally the result. Make sure your virus and spyware scanning software is up to date with the latest databases and scan regularly.

  4. Old or Broken Hardware - If you're positive nothing's changed and you've been using your system like always and these problems just started happening without any real cause, then you do need to consider that you're experiencing a hardware malfunction. One of the most common is a stuck or broken power supply fan which is now allowing your computer to overheat. However, everything from memory to your add-on cards to the motherboard itself could all cause issues here. It may be time for some hardware diagnostic work.

The bottom line when experiencing blue screens and reporting the problem to anyone is to include enough information to at least narrow down the problem. Items to include:

  • operating system version and how up to date you are

  • your computer model and what additional hardware is installed

  • what software is running at the time of the crash

  • what you were attempting to do, if anything, at the time

  • if the problem happens randomly, or if you can make it reoccur somehow

  • any changes you made to your hardware or software recently

  • any other problems or suspicious issues you've been experiencing recently

It seems most of these problems are from Compaq. I to am having this difficulty but non of these tips have helped. My friend says it could actually be the video cards or adapters. Is this true?

Hi Leo, Your solutions are a boon for computer illiterates like us. Recently I installed Intel GMA driver 946gz on my PC, this is when it started giving blue screen (memory dump). My PC came with factory installed vista home. I bought an XP professional os and using it. Now I am unable to uninstall the GMA driver(rollback). It is asking for a CD or location for old driver. If I do not do it, it is showing "found new hardware" every time I log in. Please help.

Hi, i keep getting a blue screen whenever i turn my computer on. I have tried going to safe mode with networking to see if i could download a registry cleaner but it keeps telling me that the administrator won't allow the installation. I kow i am the administrator but i can't see anywhere that i can change it. Please can u help as i keep ringing Dell and they have charged me nearly £100 for nothing at all. Kind regards Suzanne.
