I see something like a G. No time for anything, Booting loop takes less than a second

right, its too fast. try extracting frames from your video.

have you tried booting with just one memory dimm? then switch it out and try with just the other.

Yes I did this, I once removed both sticks, and then replaced one of them. This is how it is now.

That sounds like you have tried one dimm by itself, but have not tried the other dimm by itself

Hate to beat a dead horse but I don't see what your CPU temp is at idle. Can you find this in the BIOS?

one other thing, your motherboard i think has a switch to boot using the backup bios. might as well try that too

also try holding down the del key while its booting, just to see if going straight into bios will work

Does that boot into backup BIOS or restore last BIOS from backup?

if none of the above produces any improvement, its time to try a different power supply
