# Windows – How to identify the faulty driver if the computer working good in safe mode

bsodcrashsafe-modewindows 7

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.

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????

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