Solution to: BSOD - nvvsvc.exe C++ Runtime Error Can't Log in

The Problem is probably caused by:

1. Failed windows update (probably while updating either the C++ runtime library or the nvvsvc.exe or nvidia graphics driver).
2. Corrupted registry files which you can't access because of the Black Screen of Death preventing you to login.

Other indications are:
1. Can't boot-up in safe mode.
2. Can't bring up the log-in screen no matter how long you wait or how hard you click or how many times to doodle with the mouse hoping the problem just heal by itself.
3. You've tried CHKDSK hoping it's caused by Disk Error, and
4. You've tried regenerating your disk, but NOTHING WORKS.

The first method that must be employed is a "SYSTEM RESTORE" through a windows repair disk.
1. Press F8 after computer post.
2. You will see options like "Repair your computer", "Safe Mode", and etc.,. Select Repair your computer.
3. In case "Repair your computer" is not on the list, insert a Windows Repair Disk.
4. Select language and hit next.
5. Choose Recover computer through System Restore.
6. Select an earlier restore point (3 days ago or just a moment before the time you suspect the error has occurred.
7. Restart computer.
8. Problem solved.

In case you disabled (or is disabled without you knowing it though some malware or something) your "System Restore", hence no restore point is created in your/for your computer, then proceed to the next solution.
In case you have reach the point wherein you believe that there is nothing to lose by trying this solution, but only something to gain, then try this:

If you have another OS installed in the system (you have a multiboot system):
1. Log-in to your computer using another OS.
2. Locate the root directory of your computer (that disk or partition in which you installed the OS that you can't open).
3. Locate and open the "windows" folder.
4. Locate and open the "system32" folder under that "windows" folder.
5. Locate and open the "config" folder.
6. You will see a folder named "RegBack". Open it and copy (ctlr+c) its contents and paste it on the "config" folder (by now you probably are in ~windows/system32/config/RegBack, you can return to config folder by clicking back, that arrow pointing left at the upper left hand corner of the window) and overwrite anything that  requires to be overwritten.
7. Log-in to the erratic OS.
8. Voila! You are now free of that stupid error.

If you don't have any other OS, obtain a repair disk and follow this.
1. Insert a repair disk.
2. Choose a language.
3. Choose "Startup Repair".
4. Wait.
5. Select (click) Locate Driver.
6. Choose the hard disk/Partition in which your OS is installed.

Locate and open the "windows" folder.
7. Locate and open the "system32" folder under that "windows" folder.
8. Locate and open the "config" folder.
9. You will see a folder named "RegBack". Open it and copy (ctlr+c) its contents and paste it on the "config" folder (by now you probably are in ~windows/system32/config/RegBack, you can return to config folder by clicking back, that arrow pointing left at the upper left-hand corner of the window) and overwrite anything that  requires to be overwritten.
10. Log-in to the erratic OS.
11. Voila! You are now free of that stupid error.

Hope this helps.

  2. Thank you so much! I fixed this problem following your steps.

    I used my Windows 7 DVD to run the repair mode, clicked the 'load driver' button and then went to the 'windows/system32/config/RegBack' and I copied one by one files in there but when I wanted to paste it in the config folder nothing happend, so the solution is rename every single file, like SYSTEM to SYSTEM.bak (added .bak), DEFAULT.bak, etc. After that I pasted all the files (one by one because I couldn't selec all, don't know why) from RegBack without problem, rebooted my PC and now I'm writing from it.

    Thanks a lot.

  9. Step#5 Choose Recover computer through System Restore is where I got lost.
    With my Windows 7 installation DVD, I got no errors detected and no option to click or select "Locate Drivers". Any ideas?

  10. This file nvvsvc.exe should be in running process. And to overcome with this solution, one needs to use the computer cleaning software which used to clean the corrupt registry files from the PC efficiently. And If still the problem persists, then call on the toll-free number of AskPCTechies.

    Thanks for the suggestion

How to Remove and Prevent Ransomware Infection (Full Guide)

How to Remove and Prevent Ransomware Infection (Full Guide) So, you think computer viruses can’t hurt you other than hiding your files and slowing your computer down? Think again. A not-so-new breed of malware called cryptolocker (or ransomware) is spreading wildly like forest fires worldwide. Can your current anti-malware prevent ransomware attacks? One of the most notorious of these ransomware programs is the infamous WannaCry. It uses an exploit in the Windows operating system that has been leaked from the National Security Agency (NSA). In a nutshell, WannaCry, like all other ransomware, encrypts your important data and files and demands money for your files to be decrypted. Currently, anti-malware software and ransomware removal tools can eliminate the virus—not decrypt your files. How a Cryptolocker like WannaCry Works First off, you need to understand that WannaCry is a worm. A worm is malicious software (or malware) that needs not be installed. The moment you receive a cop

Pokémon Go Plus to be released Sept. 16, but is it worth your money?

Finally, the wearable tech that Pokémon Go fans were promised almost a year ago after the game has been launched will be released on September 16, 2016. A lot of people, avid fans, and critics alike have had issues with the need to keep oneself pinned to the phone’s screen while playing Pokémon Go. For one, it has put many people to danger and has even caused the accidents of some. Pokémon Go Plus is the game’s companion device designed to enable players to play Pokémon Go with minimal screen interaction. The design of the device is a cross between Google map’s pin and the Poké ball which can either be worn around the wrist (similar to a watch) or pinned to clothes. It can also be stuffed in one’s pocket (preferably, chest pocket). The Pokémon Go Plus device connects to the phone (and the game) through a low-energy Bluetooth technology (Bluetooth® Smart) that is utilized by health and fitness gadgets and devices. What the $35-device does is it allows one to catch nearby Pok
