A lot more than just capacitors could be the problem. First things first, if you have a tester, test the power supply. Next is most likely memory problem. Remove the memory piece/pieces clean the contact and memory slots (blow-out with air). Reseat the memory in proper slots. While you are in there, also check that all components are seated. Re-seating the memory should correct the problem. If not, use some different memory sticks to check again. Note: Motherboards are cheap, If your power supply is OK and you are sure the memory sticks are OK, just replace the motherboard.
From the description of the problem, it seems that either the power switch of your PC or the power supply cable is faulty. Also, please let us know if the motherboard LED is glowing or not. Do reply for more assistance.
You are going to need to lookup your BIOS version and manufacturer and find the Beep codes list. each BIOS has non beep codes and beep codes. the beep codes are bad. find out what this code means and do as they say if you dont know how to find what BIOS version your running Goole "What BIOS am i runninng?"
Once you have that like i said google it and its beep codes and if you cant find it ill help
You mentioned that you hear beeps. These beeps gives you the answer of what is the problem. It could be RAM, videocard or maybe the main board itself. It depends on the BIOS that you have (e.g. Phoenix, AMBIOS, etc.) you can see it on the mainboard. You can look on this website on how to identify beep codes:
It might usually the problem of either power supply or your RAM. So make sure you installed them correctly..
If they are short beeps then power off and reseat the memory boards, if you have more than one memory board and the problem persists then try reseating one at a time and power on, then try the other one.
Past experiences with different models of Asus of this type of problem indicates BIOS problem. I have not come across the same symptoms with ECS, Intel, MSI, Gigabyte or others but once in a Samsung. The beeping sound is actually up down (like old ambulance siren).
I have tried some correctives measures with varying results:
1. Clean the motherboard with a strong solvent, hot air dry with particular attention to the BIOS chip;
2. Resolder the bottom side of the motherboard particularly the chip holder of the BIOS; and/or
3. Flash the BIOS chip using an identical motherboard or an EPROM programmer.
If all else fails, am afraid you have to replace your motherboard. Good luck and pls post back how things turn up or if you need further information. Kind regards.
