Blue Screen Crash Dump - Driver Conflict

[Mel]

I have problem like I cannot fix by myself. Usually I can find help from the
internet with error codes but not on this case. Sometimes somehow will my
computer crash, file what is shown is BDFTDIF.SYS but it's not an malware,
it's related BitDefender (as it told me google). Anyway I wanted to find a
way to fix this but still nothing..

You can always uninstall Bit Defender if you are sure it is up to date and
still faulting the system.

I had a similar problem and it turned out that some memory was failing. I
ran a memory test overnight (memtest from the Knoppix CD) and found the bad
memory. I replaced the failing memory with a brand name replacement. Don't
buy cheap memory if yours turns out to be failing.
