Hi.. recently my old PC went bust. I don't know if it's relevant but just before I switched off the PC for the last time, I remembered there was a CD inside and opened the drive. However, before I could close the drive, the PC shut down. The next time I started up the PC, the tray went back in but then... I got nothing. No boot up screen.. no signal to the monitor. I just get repetitive , rapid beeps coming from the internal speaker. (the tiny one on the mother board. It sounds something like morse code but with just one tone). The power indicator LED on the from of the PC flickers in sync with the beeping.
I did a hard reboot and it didn't work.
I've now pulled out most of the components of the PC (graphics card , hard drive, network card ect) to try and figure out where the problem is..
Now, the only components still fixed are the most essential ; the processor, the mother board and the power supply.
That's all I know.. what do you guys think could be the problem?

Short, rapid, repeating beeps from the tiny onboard speaker mean the board never completes POST and is signalling a hardware fault — the exact meaning depends on the motherboard/BIOS vendor. ’s pointer to beep-code references is a good starting place, and ’s RAM check is on the right track. Given has already removed all add-in cards and left only the CPU, motherboard and PSU, the fastest, non-speculative checks are those that verify memory, power and shorts.

Start with a minimal, ordered test sequence: 1) fit a single known-good DIMM into the board’s primary slot (many boards produce continuous short beeps when no RAM is detected); 2) confirm the 24-pin ATX and the 4/8-pin CPU power connectors are seated and the CPU fan spins on power-up; 3) clear CMOS (remove the coin cell for a minute or use the clear jumper) to eliminate corrupted settings; 4) bench the board outside the case on a non-conductive surface to rule out a case short. Use static-safe handling and power off before reseating parts.

If the beeps and LED flicker continue, test or swap the PSU (a multimeter or cheap PSU tester is useful) and inspect the board closely for bulging caps, burn marks or bent CPU-socket pins. The front LED pulsing in sync with beeps often indicates power instability, which shifts suspicion toward the PSU or a shorted motherboard trace.

If a known-good DIMM and good PSU still produce continuous rapid beeps, motherboard failure becomes most likely and replacement or professional bench testing is practical. For a tighter diagnosis, the motherboard model printed on the PCB plus an exact description of the beep timing (continuous vs grouped, and any gaps) maps to BIOS-specific codes and narrows the fault.

It sounds like your computer is telling you what is wrong; go here to help understand what the beeping during POST means.

try to listen to the number of beeps,if it three then know that it is probably the RAM that has problem..rremove the RAM and wipe both it and the slot otherwise if the no of beeps is less than 2 problably the problem is with the processor...remove it then repeat the above procedure.....otherwise remove everything including the RAM and the proccessor and do proper cleaning......hope it will solve the problem

I don't think what I'm hearing is any kind of code. The computer keeps making short, rapid beeps indefinitely.

then jst try the last option
