Hi my hp pc will not startup...its going on yes but nothing on screen...i have change the ram try another cpu and it still do the same..its an very small hp pc desktop pc
Hmmm my sussgestion in yourr case is that, don't attach all things at once. do the following step bye step.
Step 1). Attach SMPS (power supply to the board), Front Panel Connectio, and an in built speaker and CPU (don't add RAM, HDD, FDD, VGA Card or any thing els)
Power on and watch/Listen carefully:
Case 1: if you can hear a long beep, then your CPU and board is OK
Case 2: No beep means CPU or board is faulty. Try to Reconnect CPU again and do step 1.
Step 2) Now power off and add RAM only.
Power on and watch/Listen carefully.
Case 1: if you can hear the ok beep it means till now your RAM is Ok
otherwise clean your RAM connection and add it again.
Further you can add your VGA, HDD CD-ROM/DVD, PCI Devices etc. and easily short-out your problem.
For your help here is picture of general moherboard with connection details.
Thanks

The fans are working means your SMPS is Ok and power supply goes to the mainboard.
Now your board or CPU may have faulty. If you have vaccume cleaner clean the CPU socket on the board. It might be dusty and your CPU might not be connected properly.
So after cleaning the socket. Attach CPU and try to hear the long beep for missing RAM. If not then make connection slightly temper to the board and try agian.
If you have another CPU of same configuration, you should try it.
Thanks

As a last resort I would try a flash of the BIOS.
If the bios was corrupt you would get no beeps and no video.
Try this my friend... remove the cmos battery for at least 5mins.
while the battery is out, set the jumper settings to clear CMOS. few seconds only then put back to save CMOS settings.
after 5mins, put back the battery, plcae your CPU, sonnect your power supply.... can you see if your board uses an support power supply 12Volts for the newer CPUs. its a four pin colored yellow black wires. this has to be connected to your board. But if this models supported only by 20pin power supply then you will not find the 4pin additional power jacks for the board. anyway, try this battery thing to reset the whole system. it may work.

try changing your power supply, if still does not work then you have a defective system board, only compaq can handle repair. forget about flashing bios etc... change your power supply. remove also your PCI video card and use your on board. remove all other peripherals just the basic then try to run the board with new power supply ATX.

Have you try to change the smps. check the power goad signal from the smps
the signal wire is in GREY colour and the signal will be 5volts
hi
i said change the smps .it is where you plug the power cord in the system
