Beep error codes during post are always indicative of a hardware problem. The OS doesn't even come into play at this stage.
Although I'm not familiar with the VIA boards, for the most part a computer is a computer. With that in mind, have you tried clearing the BIOS to see if that resolves the problem?
When troubleshooting a problem of this sort, have as little plugged into the board as possible. So, you should have your memory installed and that's about it. No PCI card should be installed, drive cables should all be unattached, etc. This way you can narrow down the problem.
