5 beeps cpu error, but wait.. there's a twist!

[cummbria2]

So, i am frustrated and broke. I need help in short.
I will post the specs at the end of course.
Yesterday evening my pc suddently shut down. No error and no logging out, just power gone, i was in a video call.
(I am not completely slow when it comes to hardware, but i only possess basic knowledge, what plugs in where etc) I just tried turning it on, no login or boot sequence, just 5 short, loud beeps that hit my heart harder than anything else could.
This computer is my baby you know? its my first, self built and improved computer and i was planning to improve him even more with the time.
so i looked up the beeping sequence codes and its a cpu error apparently.
after long back and forth, i exchanged my primary gpu with a really old, bad one and boom: it works.
but i spent half of my very low salary on this damn gpu and its only 6 months old, why does it give me an cpu error alarm when it seems to be the gpu that is fricking up?
A week ago i ran all the updates (windows and AMD) and since then it has been rather laggy sometime while playing and i had framedrops. physics-heavy games even tended to crash from now and then.
can it be that AMD fricked something up with their new update or something?
Is it possible that my gpu isnt able to communicate properly with my cpu anymore?
Here are my specs:

Mainboard:
Asrock 970 PRO3 R2.0 Socket AM3+
GPU(Primary):
AMD Radeon rx 560 OC 4GB
GPU(the one that works now):
AMD Radeon HD5450 1GB
CPU:
AMD FX 4300 Quad-Core Prozessor (3,8GHz, Socket AM3+, 8MB Cache, 95 Watt)
RAM:
2x Kingston KVR16N11S8/4 4GB (DDR3 Non-ECC CL11 DIMM 240-pin, 1.5V)


Edit: I corrected my foul language, i hope your eyes stop hurting now 😉

Mods will be in shortly to edit out your foul language on a family oriented website...

If you beat them to it, then perhaps you can get some help.

As for your rig working with one GPU and not another, there was a great deal of publicity a few years back about some GPUs drawing more current/power from PCI-e slot than some MBs could keep up with, which actually damaged some MBs, and caused brownouts/lockups with others.....

You can check your GPU in someone else's rig to establish that it works, which leaves your PSU being marginal, and/or your MB being marginal in it's power delivery/regulation.

FInd someone to test your GPU for a day or two, or, borrow a quality known good PSU of sufficient wattage....; when those are eliminated, you are left with the remaining culprit.
