   Hi

Specs: 
z270 extreme4
I7 6700k
Corsair vengeance 32gb
Nothing else is plugged in im testing off onboard gpu atm

I picked up a z270 extreme4 today all working well and looks okay in bios. Memtest86 run 0 errors found tried multiple settings with legacy/uefi bootmodes, updated firmware to latest, I unplugged all hdds/m2 drives still no dice.

Basically my issue is this I put windows 10 on bootable usb using rufus everytime I boot off usb it starts loading then freezes into a bsod restarts mb beeps 4 times (clock etc is set correctly) then boots into bios.

Error codes received:

Kmode exception not handled

Interrupt exception not handled

I have tried swapping mbr/gpt efi boots
XHCI Hand off enabled and disabled
Csm enabled and disabled
Security boot is disabled
Legacy usb support set to disable, enable and uefi setup only

Plz help....thanks

P.S I forgot to mention I have tried the following boot disks and oddly enough memtest86 is the only one that has worked. Trk, easeus backup, acronis true image, memtest86 and windows 10

	I finally got it working after setting the ez oc to turbo mode in bios which leads me to believe the cpu might be dying or psu is under volting. Unfortunately i dont have a multimeter to test it
