I came home Saturday night around 3am to look at my computer monitor led yellow. I knew something was wrong. I have tried to replace the battery on the mother board swapped the motherboard tried switching the video card slots everything. I am left clueless. I am not very experienced in working on computers so any help would be greatly appreciated. I am going to try replacing my video card next. I have also tried plugging a different hard drive in and it still makes no beeps or anything on power up but I know it is getting power because the fan is working. The Hd LED is SOLID RED!!
