Hello All,

Recently, I have completed a mobo & cpu swap on my system along with new hard drives. On occasion, Windows XP will just quit running, forcing a hard re-boot.
When I press the power button, I won't get a POST. Instead of the single beep signifying the POST, I'll hear alternating high-low tones (beeps) like the sound you hear from a European Police vehicle's siren. This is getting very frustrating. Everything could be running fine for weeks, then this crops up again. Could this be the motherboard or maybe memory modules? I have pulled them out and pushed them in again when this problem happens but there was no effect. Any responses are appreciated.

Regards,
Gary J.
