Hello. I read many threads with this same issue, I have tried most of what people suggest, yet I still can't get my computer to boot up. Basically when I turn on my computer, it does not post (no beeps), the harddrive light stays red (unless I remove HDD of course), and just stays at a black screen. Also the fans all are running. Also I tried keeping the power on to my computer for 10 minutes, then i felt the heatsink and processor and they were not even warm (not sure if they do get warm if they dont pass post). I tried the following to fix my computer: -Removed everything attached to the motherboard except the 20 and 4 pin PSU connectors - Nothing happened. -Tried inspecting processor for burn marks - there was none. -Tried resetting CMOS - Nothing happened. -Tried replacing PSU with a known good PSU - Nothing changed. -Tried taking the motherboard out and reseating it - Nothing changed. There are a lot of other things I have done that I can't remember, if anyone says anyone of them I will note that I have done it. Thanks.
