The post above got a bit broken, here is it fixed.
So I just bought a new PC.
It is basicly this one: click here my GPU that is a AMD Radeon R9 290.
MY cpu is the 3rd one that can be selected the 8320
PC likes to crash when I start gaming also when I run heavier stuff it just crashes.
Now it stopped working, I can't turn it on unless I go into Safe Mode.
Norma boot - Black Screen with red dots.
My friend tells me that 550W is not enough for this PC + GPU, might that be the case?
