How To Diagnose and Resolve Blue Screens of Death (BSODs)




How To Diagnose and Resolve Blue Screens of Death (BSODs)

Windows 7 is based on the dependability of the Windows NT code base, which has solid ancestry going back to the mid 90's. With ongoing arrivals of Windows, for example, Vista and Windows 7, the stage is much progressively strong. Be that as it may, Windows is as yet helpless to insecurity. In any case, are the underlying drivers of this consistently Windows? 

The Windows Memory Dump Screen 

The suitable name for this screen is 'Memory Dump.' It is uncommon on Windows nowadays, yet it happens every so often. The normal trigger for it is the point at which an application or driver attempt to get to an area in memory they don't have authorization to get to. This generally occurs because of an ineffectively composed gadget driver or application. 

Common culprits:

  • Video Card
  • Network Adapter
  • Faulty Memory Modules
  • Faulty/Failing Hard disk
  • Antivirus utility
  • Attached devices (external USB hard disk)
  • Antivirus or any application or utility that needs low level access in the operating system such as the kernel (the heart of Windows).

Diagnosing the problem.

essities low level access in the working framework, for example, the piece (the core of Windows). 

Diagnosing the issue. 

Restart: By default, Windows 7 ought to naturally restart when a BSOD happens. On the off chance that it restarts and boots up ordinarily, at that point, you can check the Event Viewer and Action Center (see beneath) to perceive what may have caused the issue. 

The Memory Dump screen will generally give arrangements you can endeavor to determine the issue with, while additionally giving data about what may have caused the issue. In the screen shot close to the beginning of the article, you will see proposals for what may be making the issue and a suggestion update the driver or debilitate it. The Memory Dump gave some specialized data concerning what framework record is related with this issue. For my situation, its luafv.sys. Obviously this is obscure, yet you may have the option to determine it, in spite of the fact that you probably won't get far since it would sound good to a product engineer. The principal thing I will do is a web search to discover what luafv.sys is. 

Here is the thing that the web list items found: 

luafv.sys (LUA File Virtualization Filter Driver) document, which is a piece of User Account Control. 

Resolution

Quest your PC for luafv.sys, and ensure, it's situated in C:\Windows\System32\drivers organizer. 

You have to empower perspective on covered up, AND framework records before you start search. In the event that you have User Account Control turned on, attempt to turn it off, and see, on the off chance that it assists with crashes. 

Obviously, not all Memory Dump issues are that effectively resolvable. Others may be equipment related. Here are a few things you can attempt: 

In the event that you constantly experience a Blue Screen, it could be equipment added to the framework as of late, for example, a USB printer. Expel it to check whether the blunder reoccurs. The SCSI card in your System Unit numerous not have a good driver. In the event that you have as of late updated your designs card, take a stab at reinstalling the old card and check whether it settle the issue. In the event that the PC more than once shows the Blue Screen and you have taken a stab at everything, for example, evacuating any outside equipment gadgets with special case to the console, mouse and screen – take a stab at expelling PCI cards. You should run equipment diagnostics provided by the framework maker. For subtleties on these systems, see the proprietor's manual for your PC. 

Update BIOS:

Your PC might conceivably require an extraordinary sort of update to work dependably with Windows 7. Profiles refreshes, in spite of the fact that suggested if all else fails, can improve similarity with introduced or updated gadgets, for example, a video card or remotely connected peripherals. Profiles refreshes are typically accessible from the maker's site. In the event that you assembled your framework yourself, the primary spot to check is the motherboard maker's site and quest for the model number. 

The Windows Event Viewer can help find what may have caused the issue, on the off chance that you can effectively boot to the Windows work area. Snap Start, type: occasion watcher, at that point hit Enter on your console. Grow Windows Logs and glance through the log for the latest mistake, this will make data in the General sheet demonstrating what may have caused the blunder. 

Use the Windows Action Center:

Utilizing the Windows Action Center can likewise give data about an application or equipment gadget that may be causing framework insecurity alongside an answer. 

To determine a flawed framework administration issue as demonstrated by the activity community: Disable the administration and affirm that this purposes the mistake. Assuming this is the case, contact the maker of the framework administration about a potential update. 

On the off chance that the blunder happens during framework startup, restart your PC and press F8 when you see a character-mode menu that shows the working framework decisions. At the subsequent Windows Advanced Options menu, pick the Last Known Good Configuration choice. This choice is best when just a single driver or administration is included at once. 

Resolving an antivirus software problem:

Impair the antivirus program, restart, and affirm that this purposes the mistake. On the off chance that it does, contact the maker of the program about a potential update. 

Check your hard disk for errors:

Run Chkdsk/f/r to recognize and fix plate blunders. You should restart the framework before the circle examine starts on a framework segment. On the off chance that the hard plate is SCSI, check for issues between the SCSI controller and the circle. You can become familiar with how to run Check Disk here. 

Faulty Memory

On the off chance that you have as of late updated the memory modules it's a likelihood that either the memory modules defective or free and should be fitted appropriately. It's helpful, at that point, to check your memory modules for blunders. 

To get to the System Recovery Environment in Windows 7, basically boot your PC, and not long before the framework stacks the Windows working framework; hit the F8 key on your console. This will dispatch the Advanced Boot Options menu. There you will see another choice for Repair Your Computer. Select this choice and hit Enter on your console. 

On the framework recuperation screen, click Windows Memory Diagnostics Tool. Your PC will be restarted and the test will be run. On the off chance that you can't boot into Advanced Boot Options, have a go at booting from the Windows 7 establishment DVD. 

On the off chance that an issue is found, it is conceivable that one of the memory modules is flawed. In the event that you have as of late put in new memory modules, check to ensure they are coordinating sets and they are running at a similar speed. One of the memory modules could be damaged, so have a go at booting with a solitary module at once to see which one it could be. 

Software:

On the off chance that you have as of late introduced any projects since you began encountering Blue Screens, take a stab at uninstalling the projects to check whether it settle the issue. In the event that you can't boot into Normal Mode, take a stab at booting in Safe Mode, at that point expel the program. 

Something else to do in Safe Mode is debilitate Start Up things to check whether any of them have any kind of effect. 

Reinstall Windows 7:

This is an intense one and the last proposal when you have depleted every other alternative. To abstain from erasing your information, have a go at doing a custom introduce over the present establishment, that way, you can recoup your information from the Windows.old organizer. To do that: 

  • Boot from the Windows 7 DVD 
  • Snap Install Now 
  • Acknowledge the License Agreement 
  • At the point when the choice is shown to choose an establishment type, click (Custom Advanced) 
  • Select the plate parcel where you might want to introduce Windows 7 and snap Next. 

You will get the accompanying admonition: 

The parcel you chose may contain documents from a past Windows Installation. On the off chance that it does, these documents and organizers will be moved to an envelope named Windows.old. You will have the option to get to the data in Windows.old, yet you will have the option to utilize your past form of Windows. 

Now don't click anything named Format or Delete or Partition. Along these lines in any event, doing a custom introduce, your own records are as yet protected. Snap OK. 

Arrangement will presently begin the establishment. During the establishment, your machine will be restarted a few times. 

At the point when the establishment is finished, you will finish the Out of Box understanding of having another framework, for example, choosing your machine name, making a username, secret key, and setting up your time region. You would then be able to continue to download the most recent updates for Windows and reinstall your applications and drivers. 

You would then be able to recoup your own records from the Windows.old envelope and reinstall every one of your applications and drivers as point by point here. 

On the off chance that you keep on encountering Blue Screens, this could be a genuine indication of equipment disappointment, for example, your hard plate or motherboard turning sour. Take your PC to a respectable PC Repair Shop for additional investigation and conclusion. Compose a note enumerating all the means you have just taken and ensure you have duplicates of your recuperation programming for the PC Repair Technician alongside any documentation that accompanied your PC. 

The Technician may likewise require access to your client record to make changes. I propose you arrangement a record with Administrator benefits so they can viably complete their assignment.
