the same thing happened to me it turned out that some of my hardware was came defected . my cpu was burned and because of that my bios burn to so something burned on your system . anyways amd is more efficient than intel but intel is a billion times better.
That is a big misconception. It is rarely ever the video card, although there is a lot of info floating around that award/phoenix BIOS only beeps for this condition.
The long beep followed by two short ones is usually a failure to detect the dram. Try booting it with a cheap stick of lower speed dram in the first slot. These boards seem to not have a good ability to recognize these faster memory timings and voltages we are now using and default with the standard settings of 1.85 volts, which cannot run the RAM at the timings in the SPD so it fails POST.
The ram and Video Card are almost ALWAYS good in this situation.
get a cheap stick of ddr667 and boot with one stick of that.
I bought a stick of it off newegg (kingston ddr2 667 512 meg) for 14 bucks, and keep it around for whenever I get the error once in a while.
