GA-H67M-D2 : Cycles power every 3 seconds

[Mbclem]

I just upgraded from a P4 3 Ghz. Installed new memory also. Power cycling happened to me also but then I thought that Windows might balk at such a severe upgrade. I  formatted the drive and did a fresh install. Everything works great now, except I can't get Dynamic Energy Saver to install.

You should always do a fresh install of the OS when you do a major upgrade as it is asking for trouble otherwise.

Make sure that you are using the latest BIOS before installing DES.

Bios is F9
what I get during installing DS2 is
"This mainboard is not support DS2.
 Setup will be abort."

I don't reallly know why you get that error message but I would suggest that you try downloading  the latest version of DES from the Gigabyte Website and try again. Personally I don't like or use any of these bundled utilities that come with the motherboards but each to their own.
