Win32k.Sys Unmountable Boot Volume Blue Screen
You’re happily working away, and then without warning, your computer throws up the dreaded unmountable boot volume blue screen of Death! This can happen following an update or software/hardware installation. In this instance, there’s a good chance that the registry entry or driver is damaged.
Rolling back the said device driver would be a good place to start, to try and fix the blue screen error. If removing a problem driver fixes the issue, you might want to check on the manufacturers website for any new updates. If you still get Blue Screen Error Codes, then take note of the error message and enter the error message into a search engine to see if you can find a fix.
Most people find it understand what the cryptic looking error messages mean, although they can help with finding an answer. And in most instances, even for a trained computer technician, the answer to the problem will still not be clear. A registry bloat is perhaps the commonest source for a host of PC issues, such as Stop Error Codes, sluggishness, freezing and DLL error messages.
Most old and even fairly new computer registries look a total mess. You should think of your PC’s registry as the gatekeeper. It stores configuration of software, applications, hardware, system setup information, user profiles, preferences and a whole lot more. In addition it keeps track of everything that’s been done on your computer including; installs, uninstalls, created files and documents, and even sites you’ve visited.
Messy program reinstallations and removals can leave unused or duplicate registries, even if you use the ‘Add or Remove Programs’ function in control panel. Quite quickly the registry folder gets overcrowded with these redundant entries, and begins to take a toll on the performance of your PC. Your computer may take longer to startup and slow down significantly.
Registry entries can become corrupted and damaged by spyware, viruses, Trojan horse, adware. There is no such thing as complete protection, but having good antivirus and anti-spyware installed and running will help to protect your PC. Ensure your running the latest update and that your antivirus application is working properly. In addition have firewall turned on, although this should be a default Windows setting.
A registry in disarray is the likeliest cause for the Blue Screen of Death and other errors. What is more, registry issues can cause instability in the operating system. When a blue screen crash occurs any unsaved data may be damaged or lost. Cleaning your registry out of corrupt and useless registry entries is an effective way of speeding up your PC. However, you have to remember that anything changes that you do make in the Windows registry, can’t be undone. Therefore you must always make a back up of the registry before you edit it.
Rushing in to fix the registry problem can cause a complete system failure if you don’t know what you’re doing. Make backups of all your files if your intent on having a go. But I wouldn’t recommend doing anything to your computer if you don’t feel comfortable or are unsure. Getting a trained PC technician to look at your PC is a better idea. An inexpensive alternative to fix your computer is to use a registry cleaning program.
