Hi,
1st : check your PSU (200w at least), more than 4.86v for +5v.
2nd : have you well modified you 1D4 motherboard ?
3rd : Have you well put the right GREX 2.2 bios for 040 ? did you use FORCE ?
4th : are you sure you have a rev2 ? did you try board type ?
5th : try to put only the voodoo on the last slot, and the terratec on the 2nd slot.
Normaly the BPPC boot menu and the early must be also displayed on the Voodoo.
