The other day I decided to turn on my computer, and when I attempted to do so, the light wasn't on, but the fans started up, and I could hear sounds of it starting up like it normally would, but then the fan didn't stop whining, usually it stops about a half second after it starts up, so I did the following:
1. Took out the CMOS battery for a good few hours, put it back in; same result.
2. Messed with a few wires[out of frustration], but everything is in its rightful place,
3. Tested a few other power supplies, same problem, and even messed with the main communication wires to the light itself, and still no prevail.
The previous day I had taken out the CPU, to maybe replace my older computer's, but it didn't fit, so, yeah;
Also, I had taken off the fan, but I'm entirely sure it wasn't damaged in any way,
Help would be greatly appreciated, I've been at it for hours,
