CPU doesn't Boot up

[Cojun]

the CPU and GPU were working just fine but then one day , abruptly,my cpu stopped booting up.

After removing out the cheap graphic card  installed in it,it works fine. But then, installing it again makes the cpu unbootable.

Does the CPU have integrated graphics?

Where are you plugging in the display cable, on the motherboard IO or the GPU IO.

[SavageNeo]

you mean the pc not the cpu right?'

 

what specs do you have?

 

so you removed the gpu and it worked? what psu do you have? what pci e slot was the pgu in?

 

try with other slots, the slot can be broken.

@SavageNeo There are other slots? I see just one slot 

And yes ,earlier my pc would boot up with the same gpu due to which it doesn't boot up now
