something new happened, it has been rotating with the qcodes for 30 minutes now, now it is stuck at 33! after I turned it off and on again
That's strange; the codes it's giving out show that it actually seems to be booting up, but that the CPU is crashing somewhere during the boot process (more specifically, during System Agent DXE). That could be due to a wide variety of reasons, but it seems to be something wrong with your BIOS, CPU, or motherboard.
You should probably try to reset your BIOS settings; you can do this by removing the CMOS battery from your motherboard for about a minute while it's not plugged in. If that doesn't work, I'd just send it over to a repair shop; they can test with different CPUs and motherboards, and I'm not too sure what the exact culprit is here.
