Computer always freezes when web browsing, no matter what browser

Windows 8 Pro, Sony VAIO VPCF121GX


I've started having complete system hangs over the last few weeks.  My fan starts spinning full speed, the mouse stops responding, and the only solution is to manually hold the power button to shut down the computer.  This happens in IE10 or Chrome under fairly light usage, maybe 5 tabs open.


First I tried restoring from a restore point before the problems began, then I tried a full system refresh.  The last resort is reinstalling Windows 8, but I'd like to avoid that.  


Question Info

I have a few questions first, to get a clear picture of the issue:


1) Do you remember making any changes to the computer prior to this issue?

2) Is this issue specific to any websites?


This issue could be caused due to some software conflicts or due to some security threats like virus and malwares. I would suggest you to try these steps and check:


Method 1:


First, I would suggest you to perform a complete security scan to make sure that your computer is free from security threats. Make sure that the antivirus program you are using has the updated virus signatures installed.


You can also download the Microsoft Security scanner and run a security scan. You can download it from here:


Note: The Microsoft Safety Scanner expires 10 days after being downloaded. The Microsoft Safety Scanner is not a replacement for using an antivirus software program that provides ongoing protection.

Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss.


 Method 2: 


If the above steps didn’t help, then I would suggest you to refer the section “My computer hangs or freezes when browsing the Internet” under Windows 8 in this link:


Method 3:


If the issue still persists, then I would suggest you top boot the computer in safe mode with networking and check. Refer to these steps:


Step 1: Safe mode with Networking


I would suggest you to boot the computer in safe mode with networking and check if the issue persists. Refer this link to boot the computer in safe mode:


 Step 2: Clean boot


 If you don’t face this issue in safe mode, then we will have to perform a clean boot procedure to find out which service is causing this issue. Refer this link to perform a clean boot:


 Note: After troubleshooting, reset the computer to start as usual. Refer step “How to set the computer to start as usual after clean boot troubleshooting” under more information.


Hope this helps. Feel free to get back to us if you need any further assistance.
