Why does my computer crash next to 3 beep after a couple of days of sitting decline?

I built a system using an Intel Desktop Board D955XCS and an Intel Pentium 4 640 Prescott 3.2GHz processor, and loaded Windows XP Media Center Edition 2005 OEM. The system, sitting vacant in Windows, crashes after 3 days - three long beep like a doomed to failure POST code, the screen go dark, and the system can single be reset with a frozen power-cycle. Does this sound similar to the motherboard may be bad? Or the CPU? We are using the CPU fan/heatsink that come with the chip.



Thank you.
