I was trying to upgrade the hard drive of a PC, the machine would not boot up; then I tried to put back the same hard drive, still wont boot up.
I did not change anything else, other than removing the hard drives, unpluged, plugged the data and power cables.
When trying to bootup the PC, I hear these beeps:
ONE BEEP........(long pause)...... TWO BEEPS...(short pause)... ONE BEEP.
I have done some research about beep codes, but have not found that combination of beeps. The closest one was:
TWO BEEPS ....(pause)..... ONE BEEP,
which means some sort of video problem.
Any help will be appreciated.
TIA

The issue might be either video (maximum chance) or memory (less chance). They may be loose. Disconnect the power, open the machine and re-seat these two guys. Issue should solve.

The beep code depends on the make of bios on the motherboard. The model of motherboard or if its a brand name computer like Dell or compaq etc, would be immensly helpful in finding out what the beep code means.

I did find this Pheonix beep code
-->1-2-1        You have a bad timer chip on the motherboard. You need a new motherboard. <--

There are a few that are close but only found two that was as you said, check them out.

1 long, 2 short, 1 long Keyboard error Either the keyboard controller is faulty or the system board circuitry is faulty http://bioscentral.com/beepcodes/mylexbeep.htm

You could try unplugging the keyboard and turning on, it might say keyboard missing but if it is this then the other error beeps should stop.

1-2-1 PIT failure The programmable interrupt timer has failed.  Replace if possible http://bioscentral.com/beepcodes/phoenixbeep.htm

1 long, 2 short Failure in video system An error was encountered in the video BIOS ROM, or a horizontal retrace failure has been encountered http://bioscentral.com/beepcodes/amibeep.htm

1 long, 2 short Video vertical retrace failure The video adapter has probably failed.   Replace the video adapter http://bioscentral.com/beepcodes/astbeep.htm

1long, 2 short Video adapter error Either video adapter is bad or is not seated properly.  Also, check to ensure the monitor cable is connected properly. http://bioscentral.com/beepcodes/awardbeep.htm

1 long, 2 short Video error Check the video adapter and ensure it's seated properly.  If possible, replace the video adapter http://bioscentral.com/beepcodes/compaqbeep.htm

1 long, 2 short Video adapter error http://bioscentral.com/beepcodes/ibmbeep.htm

1 long, 2 short Video failure The video adapter is faulty.   Reseat the video adapter or replace the adapter if possible http://bioscentral.com/beepcodes/quadtelbeep.htm
