'police siren' coming from my pc beeper...........It's a via kt 400 epox mobo
**I know that siren sound,** I have an EpoX bx440 board
Only happens when I push my 600mhz celeron up to the 900mhz clockspeed instead of my usual 750 - 767mhz clockspeeds.
at 900mhz, the CPU climbs way above the normal 38-42C.
The machine runs still, but filesystem corruption will set in.
I have one cpu fan-sink (5400rpm) combo, with no other fans (except psu)
