Hello all; thanks for reading. Bear with me while I newb my way through this!

Ever since I went from an LGA 1155 i5 3570k, to the 3770k i7 about three weeks ago, I've been running into BSODs. Most often, immediately upon log in to windows 7 64 bit.

This last instance, I was watching a youtube video. Suddenly, the power completely dropped out. It stayed down, maybe 5 seconds, and powered back up on its own. It posted fine, got to log in to W7, and the log-in sound began to skip and I got the BSOD; same thing happened on next start up.

I was having some trouble a couple nights ago; I thought I had it solved by lower clock speeds on my RAM. It was working fine until the first shut off. System specs as follows (forgive me if I list something unimportant... I'm kind of new to this!):

Windows 7 Home Premium (64)
LGA 1155 i& 3770k (Ivy) - under closed loop w/c
ASUS ROG Maximus V Extreme
16gb (4x4) of 2133mhz G.Skill Ripjaws RAM
2 ea EVGA GTX 670 4gb ftw
1200w PC Power and Cooling PSU

I think that about does it... Nothing there is real new, except for the i7, installed several weeks ago. It's currently under a preload Overclock profile that came with the maximus; @ 4.6. Obviously I may need to roll back, but I was hoping somebody could help me understand what exactly should I look for?

The crash dump is as follows:

UNEXPECTED_KERNEL_MODE_TRAP (7f)
This means a trap occurred in kernel mode, and it's a trap of a kind
that the kernel isn't allowed to have/catch (bound trap) or that
is always instant death (double fault).  The first number in the
bugcheck params is the number of the trap (8 = double fault, etc)
Consult an Intel x86 family manual to learn more about what these
traps are. Here is a *portion* of those codes:
If kv shows a taskGate
        use .tss on the part before the colon, then kv.
Else if kv shows a trapframe
        use .trap on that value
Else
        .trap on the appropriate frame will show where the trap was taken
        (on x86, this will be the ebp that goes with the procedure KiTrap)
Endif
kb will then show the corrected stack.
Arguments:
Arg1: 0000000000000008, EXCEPTION_DOUBLE_FAULT
Arg2: 0000000080050033
Arg3: 00000000000406f8

Appears to be a problem involving your BitDefender Active Virus Control Kernel Filtering driver.



BitDefender is known to cause crashes on some systems; I tried it out last year and had my own fair share of problems with it. I would recommend removing it and replacing it with Microsoft Security Essentials.



If you need further help after doing the above, please provide your full reports.





I took the liberty of moving your thread to the blue screen area and cleaning up your debugging output to make it easier to read. Best wishes the above is able to solve your problem!
