These beeps are from computers power-on self test, from the BIOS.
It is to make sure all the hardware is working during the boot process.
How many beeps, length of beeps tells you what is wrong.
Usually a hardware issue. What ever was done, try to open back up the PC and make all connections are properly fit and in place.
From what i know all 24 pins should be used, other 4 are for power supply should stay connected into motherboard, it can disconnects from the 20 pin connector, but should be together.
What i do not know is do you have a 20 pin motherboard connection ?
http://www.computerhope.com/beep.htm Check this if you find what BIOS you have.
Also at the start on taskbar and then run : type msinfo32, should tell you the BIOS there.
We can use more information listed in your post, Make and Model of PC and also the PSU (Power Supply).

The 20+4 pin ATX power connection should not cause a problem as long as the unconnected 4 pin connector is not coming into contact with the MB or any other hardware, as long as there is nothing in the way such as a capacitor etc the 20+4 pin connector can be left as one, you just plug in the power connector and allow the unused 4 pins to overhang the ATX socket, this ensures that the unused 4 pins cannot cause a short circuit, which btw could be causing your issues.
Do the above and while you are there check for any stray screws or bared wires that could be causing a short circuit, make sure that the MB mounting screws are secure (do not overtighten) check that the I/O plate at the back of the case is secure as this also grounds the MB and finally check that all internal connections are correct and secure.
If the above does not resolve the issue I suggest a barebones set-up outside of the case as this will also allow an inspection of the MB, it`s soldered circuits and capacitors.

Hey Phill, Are we saying this PSU might be for an older motherboard,20 pin .
I was not sure of this newer boards have 24 pin connectors. I though the last 4 pins are for PSU.
Member did not specify enough.

o.k. Phill, i understand it now,ty. My motherboard has 24 pins so i just plugged in all pins.
So you feel this member has a 20 pin connector motherboard and the other 4 pin connector is possibly touching something else or plugged in somewhere wrong.

True or maybe they figured it out themselves . Sometimes this happens, they disappear.

MB:
Intel DG33TL Media Series G33 uATX DDR2 800 Intel Graphics DVI+VGA 1333MHz FSB LGA775 Desktop Board
I also figured out how to connect all 24 pins simultaneously so that isn't a possibility anymore.

Gday.
Thanks for the info.
We still need the brand/model of the PSU.
For info on your MB please go to this page, > http://www.intel.com...tpboards/dg33tl
For your Installation Manual, please click > Intel® Desktop Board DG33TL Product Guide (PDF)
Scroll to page #55.
Have you got both plugs from the PSU connected?
Note that the plugs have a small locking tab to ensure they are inserted the right way around.
Please describe the beep code you get, 4 short, repeated? or a combination of long and short beeps?
