Computer woes: Long mobo beep

[Shadax]

I have the MSI K8N Neo 2 Platinum motherboard. I am pretty sure my ram is plugged in correctly because all of it's LED's light up and monitor the ram usage (whereas when I had it in the wrong slot, just one orange LED lit up). After I plug in the power and when I hit the PSU switch on, the computer immediately boots up without pressing the button. I can hold the button to turn it off, but even when it is on, I get no POST and no Video, just one long beep after the next from my motherboard (phoenix BIOS). I went to bioscentral but there is no decription for one long beep. Any advice?

EDIT: I also just installed a better CPU fan as well as a fan controller which required unplugging everything and taking out the motherboard.

EDIT X2: Ack okay I quote this from "Lounge"

10. Long(Beep) continuous DRAM isn't inserted correctly

Is this the only thing the beep could mean? I am positive it's in properly. And what could cause the system to boot as soon as I turn on the PSU switch (instead of hitting the front panel button)?

Thanks

Is there any possibility that the sound may not becoming from the motherboard? Everything seems to be connected fine, this is driving me nuts. It sounds like it just might possibly be comming from a device in the 5'' bay (I have a sound card with a device for the bay, a floppy + media reader in the 3" bay, and a DVD+/- RW in the top 5" bay). Would any of these beep and/or cause the system to not show any video??

Thanks.

Ok, I only get the beep when the speaker wire is plugged into the mobo, so it has to be coming from it. I completely took it apart and put it back together, same thing. I even removed the heatsink I installed because thats when all this started happening. Do I need a new motherboard? Can I take it somewhere?

does it make the beep when you plug the cpu fan controller into the mobo? i will bet that it is going to beep because it thinks that your fan is not working, and screaming at you to fix it to prevent cpu damage.

OK, can you tell us more about this heatsink and how you installed? How and what did you apply for thermal compound?
