windows 7 - How to identify the faulty driver if the computer working good in safe mode?


I had 64bit windows 10 computer, it then suddenly started BSOD. I tried everything in the internet but nothing solves the problem, so I just reformatted the pc and go back to windows 7. Everything went well, until I installed web browser. Everytime I open a web browser, again it turns BSOD again collecting crash dump. It works perfectly fine in safe mode. So I tried to change the RAM. It then again went very well. Everythings working fine. I was able to surf the net install and download applications. So I thought everything's is fine already until the next day, everytime I open any application that uses internet, it again went to BSOD collecting crash dump.


Are there any explanation what might causes this BSOD?


---UPDATE----


I tried the whocrashed software and based on the dump file, it might be driver issue.


enter image description here


Is there a way to locate which driver is causing a problem?Because I was able to surf in safe mode with networking.


This is the dump files.


---Update prt 2---


So, as per suggestion this might be hardware issue so I tried other hard drive and same thing happens, but this time, BSOD happens when logging in.


What's wrong with this computer????



Answer



You don't have a driver issue. Your CPU (L2 Cache - GCACHEL2_ERR_ERR) is damaged:

Windbg only shows generic Cache error, so we can't see in detail what it wrong. Replace the CPU with a new one.
