Hi All,
I have an issue with the models that I have mentioned above in fact there are 2 PC's that have the following issues -

PC1 - Continuous loud beeping sound originating from the PC as soon as the CPU is turned
on and no vga output even though the cable is connected to the monitor and the vga
output port on the CPU


PC2 - no vga output even though the cable is connected to the monitor and the vga
output port on the CPU

Hello,

Try this 1

If you notice that your CPU fan is spinning but there is no display in the screen,

then remove the RAM from the slot, clean it and place it back properly or try

another slot. Check your RAM also. Even bad RAM will result in display problem.

If you have no idea about RAM, then click on the below links.

Removing a RAM

If you are using a graphic card, then remove it and place it back properly.

Good Luck

Hi jack4rail,
We are using onboard RAM at the moment however I guess there is no harm in adding new RAM to find out if this will resolve the problem.

I have managed to resolve the issue with CP1 by adding a 1GB Ram and now I am working on the next PC however in this case I have used the same RAM and added this to the 2nd PC but I still do not have an VGA display

Hello,
Try this 1
1) Check your second PC motherboard RAM specification and make sure it matches with the RAM you are trying to use it.
2) Try resetting the CMOS settings.
Turn off your PC and remove the power chord --> Open the cabinet --> Remove the CMOS battery for 15-30 minutes and then put it back properly. Now plug the power cord back in and switch ON your PC.
Click on the below hyperlink "CMOS Battery" if you don't have any idea about the CMOS battery

Another way to reset the BIOS :
If the problem still exist, click on the below link and follow the instructions in "Hardware eset".

Hi,
I have tried this without any luck I am not sure where to go from here, in the case where the CP was beeping and there was no VGA Input Signal the beeping stops when I add the RAM but there is still no VGA signal

Hello,
Try this 1
If two RAM's are placed on the motherboard, remove it. Place one RAM and check the display.
If the problem still exists then remove the RAM and place it in the another slot. If the problem still exists then repeat the above process with another RAM.
If the problem still exists then let us know the type of beep you are getting.
Example: Is it one long beep and then two short beep.
Also let us know your motherboard brand name and model number.
Good Luck

Hi jack4rall,
I have moved the RAM around and it also seems that the onboard RAM is not working however when I add 1GB DDR2 Ram in the appropriate slot the loud continuous beeping stops now the only problem is that there is no VGA Input Signal to the Monitor which I have swapped around. The motherboard type would be that which applies to the HP Compaq dx7400 Small Form Factor PC , MS-7352 VER: 1.0
