Posted 12 March 2011 - 10:15 AM

I'm currently using a Windows Vista Home Premium Edition (Service pack 2) with an Atheros AR5007 802.11b/g WiFi Adapter.
Over the last few weeks I've been having trouble with my computer Blue Screening and shutting down at irregular intervals while I'm using it. Unfortunately the blue screen only flashes up for a second or two before turning the computer off so I have little chance to read what it is telling me.

I've been trying to sort it out with various methods explained online- I've cleaned my registry plenty of times and have become aware that the problem usually happens whenever I have "WLAN" enabled. Some googling revealed to me that this is quite common. I went to the Atheros website to see if they had any updates for my wifi adapter that could stop my issues. The Atheros Hardware Helper told me that I had to download "15 Critical Driver Updates" and when I opt to fix this, it requires me to register the program (costing me $26 that I really don't have.)

Can you suggest any other ways to stop the blue screen of death from killing my computer? Preferably without having to spend any cash.

Thank you.

I've cleaned my registry

Registry cleaners/optimizers are not recommended for several reasons:

  • Registry cleaners are extremely powerful applications that can damage the registry by using aggressive cleaning routines and cause your computer to become unbootable.

    The Windows registry is a central repository (database) for storing configuration data, user settings and machine-dependent settings, and options for the operating system. It contains information and settings for all hardware, software, users, and preferences. Whenever a user makes changes to settings, file associations, system policies, or installed software, the changes are reflected and stored in this repository. The registry is a crucial component because it is where Windows "remembers" all this information, how it works together, how Windows boots the system and what files it uses when it does. The registry is also a vulnerable subsystem, in that relatively small changes done incorrectly can render the system inoperable. For a more detailed explanation, read Understanding The Registry.
  • Not all registry cleaners are created equal. There are a number of them available but they do not all work entirely the same way. Each vendor uses different criteria as to what constitutes a "bad entry". One cleaner may find entries on your system that will not cause problems when removed, another may not find the same entries, and still another may want to remove entries required for a program to work.
  • Not all registry cleaners create a backup of the registry before making changes. If the changes prevent the system from booting up, then there is no backup available to restore it in order to regain functionality. A backup of the registry is essential BEFORE making any changes to the registry.
  • Improperly removing registry entries can hamper malware disinfection and make the removal process more difficult if your computer becomes infected. For example, removing malware related registry entries before the infection is properly identified can contribute to system instability and even make the malware undetectable to removal tools.
  • The usefulness of cleaning the registry is highly overrated and can be dangerous. In most cases, using a cleaner to remove obsolete, invalid, and erroneous entries does not affect system performance but it can result in "unpredictable results".
Unless you have a particular problem that requires a registry edit to correct it, I would suggest you leave the registry alone. Using registry cleaning tools unnecessarily or incorrectly could lead to disastrous effects on your operating system such as preventing it from ever starting again. For routine use, the benefits to your computer are negligible while the potential risks are great.

It's a laptop.
I didn't realise that registry cleaners were bad news- I used CCleaner from Piriform as i was instructed to do so on other websites. The first time i used it, i did back up the registry files that it deleted. Thank you for your advice. I shall do what you suggest and report back with the details.

CCleaner is a very fine tool, as long, as you don't use registry part.

As you suspected, most likely, you need to reinstall your wifi driver.

What's your computer brand and model?

Thank you so much for your help. It all seems to be OK now (although those pesky blue screens are unpredictable). I've been able to leave the WLAN on for more than half an hour now so hopefully it's all resolved.

Alright! I'm back.
Irritatingly enough, while watching an episode of Family Guy about an hour ago the computer shut down without showing me any blue screen. When I turned it back on it told me that the computer had suffered a 'fatal error' and asked if i wanted to find out why. When i did this it ran a scan and showed me that an error had happened (0x00000000 0x00000000 or some such similar message.) It took about 4 attempts to get the computer to turn on normally without going through all the 'fatal error' rubbish.
This time, when turned on, it shows me an error message from Microsoft to tell me that it had unexpectedly shut down (!) and then i get a message from Norton telling me that it had suffered an internal error.

Now I'm just backing up my files and seriously considering either taking this computer to a PC store and letting them sort it out and footing the bill or just getting a new laptop since this one seems far too uncooperative.

Do you have any other suggestions? I'm not really hoping for miracles at this point.

Well, we have only one BSOD and it involves system file (ntkrnlpa.exe), so it could be anything, or just nothing, if it won't happen again.
Let me know, if it happens again.
