Well the pc-repair shop could'nt fix the pc but they said its probably the MB. They also failed to get the pc to boot even with q-flash+
So i pulled out the MB and tried to use Q-flash+ again outside of the pc case......
The PC boots into bios!!!! (bios F12). (Thats with old psu and graphics card)
So is there a problem with the pc case then????
I then tried the components again inside the case....No boot! MB leds are off.
Tried to swap a psu, no boot, no leds, but then i pushed a bit against the pci-riser cable and the MB leds went active....huh?
So this could be a pci-riser cable issue?
Then swapped back to the psu inside the case and after maybe 15 seconds the pc booted (took a bit longer then usual) but now got a windows 10 error message: Looks like windows is not correctly booted....
(In the bios a changed to pci-gen 3 just to be sure).
Now i restarted and have succesfully booted in windows....I really dont get it...
