Windows 7: UNEXPECTED_KERNAL_MODE_TRAP BSOD (ntoskrnl.exe) (New Install)

UNEXPECTED_KERNAL_MODE_TRAP BSOD (ntoskrnl.exe) (New Install)

So yeah, I was getting BSOD's with Windows 8 (Which only started in the last 2 months) so It thought it might just be a compatibility error but apparently not. I freshly installed windows 7, 2 days ago and it's still going for it. I can't even boot normally anymore it just instantly BSODS when I click any program. All of the Hardware is virtually brand new, the CPU, 2 sticks of RAM were both bought at the start of the year and the Mobo, GPU and the other 2 sticks of RAM + the HDD are all 3-4 months old

DMP files (In Bluescreenviewer they all have one thing in common, ntoskrnl.exe

CPU: i5 3570k (Stock)
GPU: Palit GTX 770
Mobo: GA-Z77X-UD3H
RAM: 16GB Corsair Vengeance (4x4gb Sticks)
PSU: Corsair TX850M
HDD: Seagate 2TB Barracuda

Just some other backgroud info, The last lot of BSODS that I had that eventually made me give up with windows 8 corrupted my BIOS somehow and I only recently got that fixed. As of now everything is sitting outside of the Case because if I have to RMA something I don't want to have it take it all out again.

I await your response

AVAST was on there but then I unistalled the program because I've heard it causes BSDOS and like 10 minutes later it happened again

You logs show a: Stop message 0x0000007F UNEXPECTED_KERNEL_MODE_TRAP
Usual cause: There is a hardware or software problem. This is usually caused by a hardware failure.

Not a good move removing all the components from the case as now you are unable to run
any diagnostic tests on hardware or eliminate software in order to pinpoint the cause.

Your computer was most likely crashing @ start up because of LastPass program.

Also I suspect your issue may have had something to do with these problem devices:

Attachment 283793

I would suggest carefully installing the Motherboard/CPU/CPU Fan, the RAM (using one stick), PSU
and HDD/CD-ROM and connect all other fans.
Install any software that is necessary that came with the motherboard.

Leave out GPU and any other unnecessary peripherals.

Check all fans, PSU, CPU and chassis fans are spinning.

Install Win 7 and do not update or install any programs or drivers to the OS, except SP1:
as it will increase system stability.
Download Windows 7 and Windows Server 2008 R2 Service Pack 1 (KB976932) from Official Microsoft Download Center

Then see how stable the system is, if you experience a BSOD, post up the logs
and then we can go from there and find the root cause.

Otherwise your guess is as good as mine :)

Ok, so do you recommend formatting and then reinstalling?

I'll try just ditching lastpass on the startup and then see how it goes from there

I would recommend following this tutorial for a clean install, format the drive first if you wish
but the installer will format your installation partition for you:

Hope this helps.
