installing video card ~ Mobo compatibility issues?

i want to get a ti4200 or maybe a 9600 Pro (right now i have a tnt2 m64 32mb Pro) but i am a little worried. I got a GeForce 2 MX400 from an incredibly cheap and no name manufacturer a while back. well i installed it and it burned out after 10 min!! now i don't if this is because of my mobo or the card sucked big time..

also i heard about AGP cards that have a different voltage like my TNT2(what my computer came with)... is this ture or is it something i had in a dream?? its something like tnt2's run off a 3.3v AGP slot and the ti4200 run off a 1.5v slot?? is my mobo a 3.3v or 1.5v AGP slot??? thats what i think can screw it up

My motherboard is a FIC AZ31 that came off a Compaq Presario 5005cl

so my question is, if i get my ti4200 or a 9600 Pro from a GOOD manufacturer will it work FOR CERTIAN on my motherboard.

Sorry if i seem a little parinoid but i really don't want to waste money on a video card that doesn't work with my mobo

i have found these sites about my mobo:
http://www.s87841630.onlinehome.us/...ave/uwaver.html (the max CPU is a 1.2 ghz though..)
http://www.hardwaresecrets.com/az31.html
but they both give a little different data so i don't know how acturate they are.

Hey man,
I wold TRY to go into more detail if I could, but here is what AGP BUS connectors KIND OF look like.

_ ___
AGP-2X
_____
AGP-4X
___ _ *
AGP-8X

I know, it may be hard to work out what I mean, but if you can, you will see that and AGP-2X card will NOT go into an AGP-8X slot, unless you snap the connector!

maybe external power connectors on the card itself, or the card wasnt inserted properly?

PS: Get the 9600 Pro, they rule!!!!!!
