hi penangKia:D

I am a P5Q3 user and first time Asus mobo, unfortunately i am having some issues, hope you guys can help.

i had created a thread HERE

basically 2 problem:

1. no beep sound when i don't attached RAM and boot.
2. go into BIOS and change any single thing (e.g. disable floppy), Save & Exit from BIOS, system power down to reboot, but it will not boot up. fan everything moving, LCD screen blank with the LED on standby.

i had tried clear CMOS with moving jumper, even replace the mobo battery. but no luck so far.
here's the spec:

CPU : Q9300
Mobo : P5Q3
RAM : DDR 1333Mhz 1GB X 2
HSF : CCF
HDD : 1 SATA 300GB
GPU : IceQ HD4670 Turbo (OC 780-->810MHz; 1000MHz-->1100MHz)
PSU : Thermaltake TR2 RX 550W

thanks

hey ace, thanks again for your initiative!

okie, i have only a acbel 350W spare PSU. do you think its safe to boot up the system with it?
