Hello, I have an old broken Inspiron 5100 that I'm trying to repair. I'm guessing either the motherboard or the video card is blown. Here's what happens when I try to boot: 1) LED lights on the front come on, battery light is blinking (low battery). Both the CPU fan and the HDD start to rotate. 2) There are a few noises from the hard disk at first, but after a few seconds, it reverts to simply the constant whine of it rotating. It stays in this state until I power it off. Any ideas on what could be the problem? I tried plugging it into an external monitor and also swapping the CPU with one I know works to no avail. There are also no beeps when I turn it on, so I'm tending to believe this is an issue with the motherboard and not the video card. Thanks in advance for you opinions!
