Jerome,
You seem to be making this as difficult as possible.
If you want continued help from the several very experienced members that are try to help you, as mentioned, fill out your System Specs - Completely.
Describe all the symptoms you are having, adding them one at a time won't help anyone diagnose this issue.
From the info you have given so far, this is what I recommend.
Could be caused by the PSU, test and/or replace.1 Long Beep, 2 Short Beeps
One long beep followed by two short beeps indicates that there has been a checksum error. This means that there is some kind of motherboard issue. Replacing the motherboard should fix this problem.
Could be caused by the Graphics Card, replace it with a new one.
If that doesn't fix it then:
Replace the motherboard.
If that doesn't fix it then:
Replace the RAM.
If that doesn't fix it then:
Replace the CPU.
If that doesn't fix it then:
Replace the HDD.
If that doesn't fix it then:
Replace the keyboard and mouse.
If that doesn't fix it then:
Replace the computer.
Or, you could give us something to go on, check for BSoD generated mini dumps, check your event logs, check that all your drivers are up to date.
