Dude I had this same exact problem not to long ago and sadly it lead to my motherboard being fried. If you take out compnents while the computer is on or turn on the computer when something isn't put in correctly odds are the motherboard is dead. I had this problem and had to pay to get a new computer, get my OS switched over to the new computer and my GPU switched over. Cost around $400+. The computers is far better than my last one but meant me paying little over $400 to fix the issue. To be clear the computer itself cost $400 and the fee to get everything transferred was $50
