I just refomatted a friends computor and he has an old SB sound card and a Gadget Wave 4 card,for guitar work.It worked fine before the format with both cards but now when i install the wave 4 card drivers the system will not boot up,blue screen of death.Is there something iam missing when installing these two cards? It worked before.With the sound blaster i installed everything on the disk.Should i delete this and only install the basic drivers?Help!
