Morning:
My Pc was running fine.
I got some windows updates installed, I didn't check what they were, got them installed after a restart and turned off my PC
Afternoon:
My PC entered boot loop at POST, it tries to get into the bios by itself but restarts immediately.
What I've tried:
1) Disconnected all SATA drives and peripheral devices. (Result: No change)
2) Removed my GPU, connected my HDMI to my MOBO.(Result: No change)
3) Tried a different RAM stick (from my old rig).(Result: No change)
4) Tried to run my old RIG off the PSU I use for this PC, it works fine.
5) Tried my RAM Stick on old RIG, it works fine.
6) Tried to enter Dual Bios by holding the power button until a complete boot cycle and then pressing it again.(Result: MOBO didn't try repairing my main BIOS, no change )
7)Cleared CMOS by shorting CLR_CMOS and holding power button for 15-20 seconds with PSU removed (My mobo doesn't have jumper, it's just two pins I could find, took care of grounding, Result: no change)
8) I can't find another LGA1150 Mobo to test my CPU (LGA775 and FM2 everywhere -_-)
9) Made sure my MOBO standoffs are high enough to avoid shorting on pins on the back of my MOBO.(Result: No change)
10) Cleaned Dust (Result: No change)
I don't rely on youtube videos or random google search results or stupid forums where I'm told to clean dust properly, or try reinstalling windows or made to jump into the "OBVIOUS Conclusions"
of dead components.
I am no expert, please advise me.Thanks in advance

By the sounds of this your BIOS may have become corrupted. If this is the case it is probably better to contact Gigabyte as messing around with it may cause permanent damage. Do you have the Gigabyte App Center installed?
