POST-Beep-Code List availible for Phoenix-BIOS? ECS 755-A2
I cleaned my Power-supply from dust by vac. Rebuilt it in the case, pluged in all conections, and after turning power on i got one single long beep followed by the same after a few seconds. What the hell does it mean? (ECS 755-A2, Phoenix-BIOS, AMD3000+, 2x 512MB DDR-II RAM (PC1600) , ATI Radeon 256MB) Where could I get a complete POST Beep-Code list for different Bios- manufacturer (e.g. AWARD, Phoenix), or are they the same?

First ingeneers build things to fuction AS IS, so i'm not sure you need more fan power.
Verify the inside of the computer is the CPU heat sink (big aluminium block with fan) CLEAN of any dust? are all the fans turning correctly (resonable speed)? verify the placement of the PC itself is it cooked up in a cabinet or pushed against a wall (blocking the holes in the case for air intake)?
if all of the above is OK you could re-paste the CPU (spreading new heat sink compound between the CPU and the heat sink)
Your issue sounds as though it is the power supply that is in need of replacement. If there is a steady red light on then the PC unit is not getting it -12/+12/-5/+5 voltage at the connectors also you may have inadvertently switched the cable connections that is pin 1 of the cables is not getting the voltage it needs to the device. The red line on the cable or the (+) is the supply pin to that device. 1. check the power supply and all the connectors. 2. clean all dust from the inside of the the connector and around the CPU 3.check the CMOS battery (looks like a new quarter) should show 3.7 volts with a volt meter. If readings are below this you need replacement. I hope this helps. Have a great day!
clean the cpu cooler slots and replace the thermal compound on the cpu ....make sure you clean off the old thermal compound .....only a thin layer of new thermal C will do all most see through ... hope this helps my friend
Leave the memory slot closest to the processor empty and try booting again. Award bios 1 long beep is memory error as the first 64K of the ram stick closest to th processor is accessed first. since you have tried different ram in different locations, let's rule out the board.
If that doesn't solve anything try a different power supply. Sometimes (Phoenix) gives a long beep when system board or power supply are bad.
Now if nothing else has worked it is probably tour mother board.
The repeating single beep with a small pause (actually 3 Beeps a Pause) clearly indicates problems with RAM .Replace it ,your problem will be solved . As for connecting the 12 volt 4 pin connector all mobos are designed to sense the presence of this 12 volts and ONLY THEN TURN ON.
If you look on the back of the set, there will be
a chasis # probably a CTC169 . These sets usually
need to have the power supply repaired. These are great sets and have an awesome picture. There is a
kit,I which is available to service technicians which will repair the power supply in most cases.
If you can find a good local technician , they should be able to repair this problem for approx
$125-150. if you have further questions pertaining to this set , I will be happy to advise you. I probably have repaired a coule hundred of these sets. This is one of the few old crt sets that are worth fixing. Scrivitron
