4 days ago my computer was working perfectly fine. Until yesterday when I tried turning it back on, it doesn't work. Usually when I press the "on" button, a blue light lights up. This time when I press the "on" button, there was a blue light that lite up but only for a split second and then the light was gone. I tried pressing the "on" button a couple of times afterwards, but there was no response. I checked all of connections but I did not find anything suspicious. I even disconnect everything from the hardrive and directly connect it to the wall outlet, but the results were the same. Please tell me my motherboard is not crashed!!! I have some very important files inside the hardrive, so I am desperately looking for help. Please teach me how to recover the hardrive. Please.
