Thanks Ted. I think I found the cause of my trouble and I will share it as it is unusual.
I am using a Soyo P4VGM main board with 2GB ram in two machines. Windows XP SP2. Dakota card in one machine and a RME-AES card in the other.
Midi Over Lan as midi interface.
I have used these devices for a few years and have run well as stand alone GigaStudio machines.
I installed two Seagate Barracudas in each machine. 250GB 7200rpm.
I upgraded the system and Gigs drive in each machine with fresh install of Windows XP and GS3. On each machine I got the same freeze on both machines.
Freeze on GS3 splash screen and hard drive light stays on. Reset is only option out.
So what did I do? It looked like a hardware freeze. So I eventually swapped the IDE cable from the IDE-1 connector to the IDE-2. Then no troubles. Now my internal DVD is on the IDE-1 and the System drive and Gigs drive is on IDE-2 as Master and Slave.
Seems to have fixed it. I did the swap after the install of all software.
I am interested to know what you think could cause this?
