Hi
guys I need help bad
I got a new v-card, its a Inno3D FX5200 128mb 8x card
I installed the thing and now my screen blinks now and then and the computer also freezes now and then

pretty much impossible to use
anyone know what this might be ?
my motherboard is a gigabyte 7va-c (the book didnt say anything about 8x agp so Im thinking maybe its no supported or something ?)
also I checked the power rails and the 5v and 3.3v are behind, the 5v shows 4.73 and the 3,3 shows 3,21 - could this be the problem ?
please help, please please
Thank you
Dan
