If, while using your computer, you encounter the ACPI.sys Blue Screen error, read on as this post will guide you in fixing the problem. The ACPI.sys file is a Windows operating system file that is related to the MSDN 2939. ACPI.sys, the Windows ACPI driver, is an inbox component of the Windows operating system. It is the one that supports the power management as well as the Plug and Play or PnP device enumeration. And so if this file ends up getting corrupted, it is known to cause a Blue Screen error. Another possible cause for the ACPI.sys Blue Screen error includes RAM issues, incompatible firmware, hard disk issues, corrupted drivers or malware infection, and so on. Here are some Blue Screen errors that can be triggered by the ACPI.sys file:

• KMODE EXCEPTION NOT HANDLED
• PAGE FAULT IN A NONPAGED AREA
• SYSTEM THREAD EXCEPTION NOT HANDLED
• IRQL NOT LESS OR EQUAL
• KERNEL DATA INPAGE
• SYSTEM SERVICE EXCEPTION

To fix the Blue Screen error associated with the ACPI.sys file, refer to the instructions provided below.

Option 1 – Try to recreate the ACPI.sys file

If the first option didn’t work, the next thing you can do is to recreate the ACPI.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. This is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.

• Boot your Windows 10 PC in Safe Mode.
• Then open File Explorer and navigate to this location: C:/Windows/System32/drivers
• From there, look for the file named ACPI.sys and rename it to ACPI.old.

Note: As you can see, the file’s extension has changed from .sys to .old.

• Now restart your computer and check if the ACPI.sys Blue Screen error is now fixed.

Option 2 – Try to update or rollback the ACPI Driver

The first thing you can try to fix the Storport.sys Blue Screen error is to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Tap the Win + X keys to open the Win X menu and from there, select the Device Manager.
• After opening the Device Manager, look for the ACPI.sys driver and right-click on it, and then select Properties.
• Next, go to the Driver section. Note that the rollback option would only be available if you’ve recently updated the ACPI.sys driver. So if you can’t see it then click on the Update Driver button.
• After that, Windows will automatically check for the problems that could be related to the Blue Screen error.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can also directly download the relevant drivers of your computer from the manufacturers’ website. So if you have an SSD, the issue might be due to an old storage driver. On the other hand, if updating the ACPI driver, didn’t work, you can also try to copy the ACPI.sys system driver file from the System32 folder of another computer that’s functioning properly and runs the same Windows OS version. Afterward, place it on your problematic computer and check if it fixes the BSOD error or not.

Option 3 – Run System File Checker or SFC scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

 Reboot your PC.

Option 4 – Run the Blue Screen Troubleshooter

Troubleshooting Blue Screen of Death errors wouldn’t be complete without the Blue Screen troubleshooter. As you know, it is a built-in tool in Windows 10 that helps users in fixing BSOD errors like ACPI.sys. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 5 – Run System Restore

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.

From the various report, it is now clear that no one is prone to Ransomware attacks. Cyber-criminals never target any specific field of the user workgroup for this Ransomware attack. But in past few years, it has hugely affected home users, businesses, organizations. We can say, Ransomware victims come in all shapes & sizes. Many business owners think that they will never be attacked by Ransomware crooks because their business is not so big. But that’s not true. A huge proportion of Ransomware attacks happened in small sector businesses because of their weak security resistances.

Some leading negative consequences of Ransomware attacks faced by almost every victim are:

1. Permanent or temporary loss of proprietary or sensitive information.
2. Lots of trouble in performing regular operations.
3. Huge financial losses sustain for restoring up your files and systems.
4. Latent harm to the reputation of an organization.
5. Even making the Ransom payment doesn’t guarantee the safe releasing of your encrypted files.
6. Attackers get the victim’s money along with their banking details.
7. Getting the decrypting files doesn’t mean malware infection has completely been removed.

Ransomware put a tremendous impact on disturbing business operations and in the end, leads to data loss situations.

Here are some huge impacts of Ransomware attacks on business are:

1. Damage or loss of all the crucial information
2. In the Ransomware post-attack period Business disrupts a lot.
3. Destruction of hostage data, file, and system.
4. Business downtime
5. Victimized company’s reputation dropdown
6. Productivity loss

Apart from the ransom, the cost of downtime because of restricted system access will bring major concerns. It’s a fact that due to downtime victims may has to pay a cost of ten thousand dollars daily. As, Ransomware is becoming more and more widespread, so all companies require to brush up on their annual cyber-security goals. Moreover, approach for some appropriate implementations of Ransomware recovery plans and commit sufficient funds in their IT budgets for cyber-security resources. Among the most effective impact of Ransomware, “data encryption” is very hard to deal with. Meanwhile, this victim is completely restricted to access any of their encrypted data. The only way for unlocking these encrypted files is through the decryption key which only belongs to hackers. Many times, the decryption key is given to the organization, after the payment of the ransom. But there are also some cases when data is not handover to the victim, even after the ransom payment. The main risk that generates with “operational impact of Ransomware” is on the businesses. Can you just imagine, what will happen if all of a sudden entire services or processes of your business halt down?

Well, this dreadful Ransomware threat is so impactful that it can:

1. Close down the entire plant
2. Freeze manufacturing control system
3. Make other backlogs

All the damages that occur due to downtime can be a major one and can have so many consequences. A well-organized strategy of backup and recovery will not certainly make the Ransomware attack painless. As this takes an extensive amount of money and time for data restoration.

Apart from that, the decision of recovering your system using the backup moreover depends on three things:

1. First the amount of data loss that is considered acceptable by your business or organization.
2. Up to how extent, the impact of Ransomware has spread
3. How fast the Ransomware attack was spotted.

However, in many cases, data gets so encrypted that you can’t revert back to the restore point. At that time external backup is considered the best option. Among the wide-reaching impact of Ransomware “Data loss” is the most effective one.  As it starts from little disruption and leads to permanent business failure. Sometimes data loss in a Ransomware attack leads to disclosure of all your confidential information which ends up in fines and lawsuits. Attackers always look for backup files and folders after encrypting your system data. So that user can’t retrieve their corrupted file from the backup. Such dreadful activities make this Ransomware threat so profitable and effective. Victims don’t have any choice left either they have to pay the ransom or they have to face their risk of data loss.
