I have the same problem on 2 PCs. One is running Windows 7 and the other Windows 8.
On the windows 7 PC it is worse than on the other one.
The PC boots normally until the first sound, where normally (when BlueSoleil 10 is not installed) the logon screen appears immediately.
But when BlueSoleil 10 is installed, there is a delay for about one minute between the sound and the logon screen. During this delay, the hard disk is used intensively.
Can IVT explain, what BlueSoleil is doing there?
