Can broken connectors cause bugs, errors etc.?
Yes! Especially the inside of your computer is very sensetive for broken contacts. Doesn't matter if its one, one-half or ten. It causes that the contact can't anymore send clearly siganal from the motherboard to the graphics card and then you get errors.
A list of possible errors that a loose contact could cause:
- Causing other errors and problems
- Short circuit
- Software errors
- Damaging other hardware on board
As you can see in your example this broken slots/ connetors caused "The card was sometimes not detected in the Slot and stopped working randomly"
So, what can I do?
I don't know but how this happened! But if it isn't caused by you (for eample thought such violent action or carelessness using) then it's a error caused by the producer. So if you still have warrenty on your graphic card, pci/pcie-slot or whatever I would send it to him to fix this damage!
However if you don't have warrenty or if its your falt, then you should send it to the producer or any technical workshop to repair it. But then you need to pay for that. So if the repair price should become too expensive you should think about just to buy an new graphic card ;-)
