Building a 2.5 celeron system, with a P4VMM2 Motherboard, 40 GB Maxtor, 300Watt power supply.Problem is, all hooked up turns on, but there is no display.Have Tried to reset CMOS to no avail. Any help would be appreciated.
 
I get the fans on, and the harddrive is running. Nothing else happens, no post or anything.I actually just tried to turn it on now and it wont even turn on. any ideas would be appreciated. THX

ok, now it boots, there is not even a post or anything, just the fans are running and you can hear the HD running.

Install/connect only the power supply, MB, CPU, memory, video card, monitor, case speaker, and power button, and make sure the power supply's voltage selector switch is set to the correct voltage and the PS connection to the MB is securely seated.
Then, try a different monitor.
If there's a display, then replace your monitor.

If there's no display with a different monitor or if your monitor works on a different system, then check the CMOS battery for the correct voltage(3V).
If that's ok, then make sure the 'Clear CMOS' MB jumper is not in the 'Clear' position.
If no luck with the above, then place the MB on a piece of cardboard. If there's now a display, then the MB is shorting out when installed in the case. Check for a loose screw, standoff, etc., inside the case, and also remove any standoffs which do not line up with MB holes. If none is found, then remove all MB screws and metal standoffs, and install paper washers(manila folder paper works good for this) between the MB and the screws/standoffs.


If there's no display with the MB placed on a piece of cardboard, then proceed with the following:
(1)If all fans and lights work when the 'Power On' button is pushed but there's no display, then test the following PS leads on the back of its MB connector making sure the connector is installed on the MB and system is powered up with the 'Power On' button:
yellow wire and a black wire- +12V
red " " " " - +5V
orange " " " " - +3.3V
If these voltages are not up to spec, then the PS is bad.
(2)If the PS voltages are ok and there's no display, then either the MB, CPU, memory, or video card may be bad. Make sure the correct memory type is being used, remove and reinsert the memory a few times making sure it's firmly seated, install the memory in different slots(some MB's require that their memory slots be populated starting with slot 4 and not slot 1), and make sure the video card is firmly seated(some video cards need an extra firm push to seat properly, and some may raise slightly out of the slot when the hold down screw is fully tightened). If still no display, then swap out the MB, CPU, memory, and video card to find out which one is defective.
