|Well for one thing it could be the power supply. What brand is it? You know, just because you may have a 1000 watt power supply doesn't mean that it's not going to be a problem. If your supply is a decent one like Thermaltake, Antec, or Corsair, we may be able to rule that out as being the culprit. If it was working fine with the old board, that could be even more reason to rule it out. But until we know what brand it is, we can't rule it out completely.|
Another thing could be the RAM. But then again if it worked with the old board, the only possibility of them being faulty would be if they have been mishandled and damaged due to static electricity. You should hold RAM by the edges, not by the sides. It only takes 400 volts of static electricity to kill electronics. When you feel a static shock, it's atleast 3,000 volts. But the only way to test the RAM is if you test it in another compatible PC.
Another possibility is the video card. The only way you can tell if this is the culprit would be to try it in another compatible PC.
The next possibility is the motherboard. DOAs are very common and perhaps you just happened to get a DOA board.
BTW, why was it that you changed from the Intel board to the ASUS board? Was there a problem with the Intel board?
