One long beep and then three beeps in a row? It's not detecting correctly your ram modules. try placing just one and see if it boots

Just an addition to what Marc posted. I just built a new machine with 4 X 4Gb memory sticks and had a similar error. I had to take the sticks out, one by one, and test them in the first memory slot and, lo and behold, one of the sticks was bad. That may be your problem, or, you might have the sticks in the wrong slots. On my ASUS board, slot 2 was the slot for a single stick. Slots 2 and 4 were for 2 sticks. You might double check your motherboard manual to see if you're using the correct slots.
Also, some motherboards have a list of approved memory. With ASUS, if you don't use memory from their approved list, it may also cause a problem. Something else to look at.

ok. thanx guys. Let me clarify on the ram. Both computers were working fine. Both are HP with Phoenix Technologies motherboards. I switched the ram between computers. both are ddr2. They both had stock ram. The 2.4Ghz dual core came with 2 2GB sticks and the 3.0Ghz came with 2 512Mb. The 2.4 only has 2 ram slots and I put both 512Mb sticks straight outta the other working HP in that. I'm gonna try a few things and review the beep code list and will get back to ya and let you know.

Ok gents, I tried all the advice to no avail. The beep codes I looked up don't match the codes I'm getting. With the ram is 1 long beep, without is 1 short then 1 long.

Those beeps don't seem to match up to anything I can find. If they are, in fact, Phoenix brand bios' then they should match something on this link:

Even my ASUS mobo's have 3 or 4 series of beeps as warnings. The shortest being 3.

The only way to investigate further would be to get the motherboards part number, the Phoenix bios version number and try to match it up in a google search. Every RAM stick I have has a part number. That might help if the motherboard manufacturer has a list of approved memory.

On the right hand side of the link I gave you, there are links to bios beep codes from other brands of bios'. From what I can see, whenever a long beep is involved, it tends to point to a RAM problem, either regular RAM or GPU RAM. Without exact part and version numbers, it'll be hard trying to narrow it down.
