Hi all,
I booted my laptop 3 days ago, started browsing online and then the screen became filled with colourful lines and grey noise interchangeably. After several failed attempts to boot normally (it kept occurring) I decided not to use the laptop that evening.
The next day it booted up normally and I did scans for viruses and malware, as well as, chkdsk, (though I'm not sure how relevant that may be). It worked well that day but since then I have been having the same problem this time more frequently and now it keeps shutting off before it reaches the windows screen.
I tried using another monitor but the problem shows on that monitor also.
This is the first time I've encountered this problem.
Any assistance/ guidance provided would be greatly appreciated.
Thank you in advance!
I have attached photos of the screen issue.

Laptop Specs:
OS : Windows 8.1
Manufacturer: Samsung Electronics
System Type: 64-bitOS

Welcome to Bleeping Computer.

 

Please post the make and model of this computer.

 

 
Please download and install Speccy to provide us with information about your computer.  Clicking on this link will automatically initiate the download. 
 
 
When Speccy opens you will see a screen similar to the one below.
 
speccy...1png_zpsr3irze6o.png
 
Click on File which is outlined in red in the screen above, and then click on Publish Snapshot.
 
The following screen will appear, click on Yes.

The following screen will appear, click on Copy to Clipboard.

In your next post right click inside the Reply to Topic box, then click on Paste.  This will load a link to the Speccy log.
 
 
Boot into Safe Mode and let me know if this problem continues or not.  Safe Mode uses a limited number of drivers and applications.  The graphics drive use in Safe Mode is not the one you usually have when you run Windows normally.  The Safe Mode graphics driver is native Windows driver.  If the problem doesn't occur in Safe Mode this usually is an indication that there is a problem with the graphics driver.
 

How to boot into Safe Mode in Windows 8 or 8.1
 
You will need to use an Administrator account to for this.
 
Press the Windows key windowskey_zps092d5c75.png and the X key together.  In the menu that opens select Search.  When the Search charm opens type in msconfig.
 
msconfig will appear below the search box, click/tap on it.
 
When System Configuration opens click/tap on the Boot tab.
 
Under Boot options click/tap on Safe boot, then click/tap on Apply, then OK.
 
The next time you start the computer it will boot into Safe Mode.
 
Please note.  You computer will continue to boot into Safe Mode when it is started until you go back to System Configuration and remove the check in Safe boot.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Thank you both for your replies.

I tried booting the laptop, but it only displayed the Samsung logo, went to the same screen issue (as posted above) and then it kept shutting off. After several attempts, I was finally able to get it to boot and stay on thus far. I've followed your instructions for Safe Mode and after replying to this post I will reboot to see what happens.

 

As for Speccy, I seem to be getting an error....

That Speccy error is regarding Windows Management Instrumentation which is the service speccy gets the system info from.

 

Make sure the service is running and not corrupted ( however your sfc indicates there may be a possibility it is, and possibly other things are too)

 

(also at the moment cannot remember if WMI service even runs in safe mode if that's where you run Speccy)

WMI should be running in either normal mode or Safe Mode.

 

To see if the service is running press the Windows keywindowskey_zps092d5c75.png and the R key at the same time.  This will open the Run box.

 

In the Run box type in Services.msc, then click/tap on OK.

 

When services opens scroll down to the WMI service (Windows Management Instrumentation service).  There are five columns in services, look at the Status column to see if the WMI services is running.

 

Do this in both normal mode and Safe Mode.  If the services is not running double click on the service and click on Start under Services status.

Hi again,

I didn't power on the laptop for 2 days until yesterday. It seemed to boot normal. WMI was running but Speccy still didn't work.

 

I did a few thing; namely:

* I disabled adobe in Services.msc

* Changed anti-virus (Avast to Kaspersky)
* Tried to update to windows 10 but it rolled back to Windows 8
* Did a malwarebytes anti-malware scan
* Downloaded and ran SUPERAntiSpyware Free edition
* Used Windows Repair (from Tweaking website) abt 3x in Safe Mode
* Chkdsk &

* Memory test

 

Speccy seemed to work after that:

I wasn't able to get Speccy to publish in safe mode though.

 

*Thanks again for the replies & Happy Holidays to all :)

You can not run Speccy in Safe Mode.

 

Please post the logs for the scans you ran and posted in your last post.

 

Merry Christmas :santa:
