When I open my computer, It doesnt have Bip sound which every open I have. And nothing in monitor. But fans and hdd and cdrom are working. I try to change Ram and Graphic Card from my other compiter but nothing changed. I take BIOS battery and wait. And nothing changed again. What it could be?

(problem starts with my mouse freeze but keyboard was working. I restarted comp and it can not open now.)

Thanks for Help...

    Accepted Solution

    If it does not beep, it should be:
    1) Dead CPU (after overheating or something)
    2) Dead motherboard (check if capacitors are not deformed)
    3) Dead PSU (check voltages when powered ON using multimeter, should be +-5% of the target values). It might still produce 12v, but have dead 5v lines.

    as barsmon says, sounds like a dead mobo/cpu  or a broken power supply. if it was just the RAM is would beep.
    sometimes a build up of static stops all from working. - disconnect the power cable hold in the on button for 30 seconds. retry the power.

    i suggest testing with the minimum setup - disconnect also all peripherals and network cables :
    motherboard + cpu + 1 ram stick, video card, power supply
    on boot, do you have a display?
    if NO it is one of the connected, swap ram, Power supply, video card - leaving only motherboard and cpu
    if Yes, add devices till the problem shows

    you can also check the motherboard for bad capacitors as shown here :

    Remove ALL the RAM and then power on.  You should hear a continuous beep.  If not - the mobo is likely dead.  If you DO hear a beep, follow nobus' procedure above.
