Hi , I just decided to sell my athlon 2600+ system to my sister, it's a GA-7N400-L (http://tw.giga-byte.com/MotherBoard/Products/Products_GA-7N400-L.htm), everything was perfect, it's installed in a antec sonata case, I installed XP, etc...

She came here, I went to boot the computer and kept beeping long enless beep... so I check and It's said dram problem in the manual, so I changed the ram, same problem, try the board with a different case/power suply, same prob. so I went back to the store, they exchange the board and the amd processor, went back home, re-installed, = same problem!!

So I need some help, this setup worked for a week with the sandra+prime95 test, and then.... beep at startup, beep that last 4 seconds ent doesn't end... so it seem like the ram is bad, but tried a different board, processor, power supply etc.. is this another bad board?

And BTW, I have a athlong 64 on a ga-k8n pro, is this a good board? i'm kinda scare now of gigabyte!!

please help!!!

Well, is it possible that you might be wrong as to what the beep is doing? According to this link there are other codes that point to a video problem; including a continuous beep. At any rate, since you seem to have eliminated the memory, that would be what I would check. Change the video card and cable if possible.
As a test you might also want to pull the RAM from the system and try a boot to see what, if any difference there is with the error code/beep. You might also want to try utilizing just one memory slot at a time and rotate which ones you do to see if one or more slots are bad. It's a long shot but that's kind of where you are now. That might also help narrow down a particular bad stick of RAM.
