Just wanted to know what is the best way to find a faulty driver.
Hello and welcome to Techspot!
Edit: with the addition of your minidumps, I have deleted my original response.
Two of the dumps are caused by 6z2yZ4py and 419c69X, my guess is they are the same file. It's an infection of some type and it's being renamed to avoid detection. The third one has a bugcheck of C4 - see below. You need to do a virus\malware scan and possibly a rootkit scan. Could you also post the cause if you find it.
A device driver attempting to corrupt the system has been caught. This is because the driver was specified in the registry as being suspect (by the administrator) and the kernel has enabled substantial checking of this driver. If the driver attempts to corrupt the system, bugchecks 0xC4, 0xC1 and 0xA will be among the most commonly seen crashes.
Hello and welcome to Techspot.
I agree with peterdiva. You may have a virus infection.
Go and read this thread HERE. Post a HJT log as an attachment into this thread. I`ll take a look and advise.

Are you still having problem?
After running Verifier.exe from windows, i tested all unsigned drivers. After reboot I then got another bluescreen.
Here is my resent minidump file.
2 of your minidumps, including your latest crash at VETMONNT.SYS. They also reference vsdatant.sys. These are your antivirus and firewall programmes respectively.
Disconnect from the net and temporarily uninstall your antivirus and firewall software. See is your system becomes stable.
Do not reconnect to the net, until you have reinstalled your firewall.
Everything seems to be working fine. Thanks for the help.
