@abdullahso19894 why would you think it's an electrical problem. You have not told us what you have checked or what you have tried out. Here is the [https://dl.dell.com/manuals/all-products/esuprt_desktop/esuprt_inspiron_desktop/inspiron-580_service%20manual_en-us.pdf|service manual] that will help you to work on it. You will also need to let us know what OS you are using and if you have tried to see if this is possibly a Software issue. Open it up and check that the wiring is still fully connected.
