I my case that was RAM. Had a continuous beeps from motherboard with no boot, checked everything, except memory on my second comp. Whole time (I lost almost whole day in great great frustration) I thought its video card because monitor signalized "no vga signal". Finally I pull up my three RAM modules and tried to install it randomly. Succeed with the first one farthest from CPU, got boot. After that I install the second one next to the first, again got boot, finally tried to install the third one but again got the problem. So I start from the beginning, this time installed only two of modules on same places like before, without the third one, and my comp is now working.

Note: The modules are of the same memory PC2 - 6400, but not from the same manufacturer, two kingmax and one mushkin. The problem was with the mushkin. I also have to note that comp worked almost 3 years with those 3 modules without problem, when i buy a new one, and left this old one. The problem with beeps arise after two years when I tried to use it again for my children.

Hope this will be helpful.

First thing to try is testing each RAM stick by itself.
If the computer won't boot with any one of these, that stick is faulty.

If your CPU has two RAM channels (most common configuration), three RAM sticks is an unusual number that wouldn't normally work.
What CPU and motherboard are you using?

Vincent. It worked normally. When I bought comp it has two memory sticks, 1+1 GB, and later I upgraded it with one more, also 1 GB. All this time with upgraded memory, no problem at all. But after two years of it wasn't used, first time I start it, the problem with beeps, and no boot arise. Anyway the configuration is: MB Abit kn9 ultra, CPU Athlon x2 5200, VGA GF 9800 GT, HDD WD 300 GB, RAM kingmax 1+1 GB and mushkin 1 GB, all three of them PC2 - 6400, PSU Chieftec 500 w.

Note that I am not a hardware professional, just ordinary user which have no fear if there is a need to open a case and try this or that. But Ill keep in mind what you said about memory channels during the memory upgrade of my new comp.
 
This motherboard supports dual channel memory, so you would generally use 2 or 4 sticks of memory.
It will work with 1 stick (memory bandwidth is halved), but 3 may not work.

If the three were working previously however, I guess that isn't the issue.
If you remove the two sticks that are currently working and install just the one other stick, does this work?
If not, throw this stick in the bin.
If it does, there could be some compatibility issue.

Also, if you turn a computer on after two years and the BIOS won't remember settings, it is probably the CMOS battery (button battery in a holder on the motherboard).
