I have a HP Brio Celeron 733 MB # D9840-60001... that will not power up.
I hit the power button, it turns green, as long as you hold it in.
It does a High/low sound fast several times, then pauses,
Then it Beeps twice about 1 second each time.
It won't power up.
I checked all cables, removed HD, cards etc.
Same thing.
10 pin p/s and a 6 pin.
Any advise would help.
Thanks:confused:

OK Bios beeps two usually indicates memory issue, or error in memory type.\
Try moving memory to last slot or reversing it in present location. Easily done when using ddr, slot is nearly center. Other twin bios is sometimes floppy drive, Google board and bios beeps for your board. Mark::
