Bios/grpahic card failure

Specs: Windows Vista
This problem is new to me and all the people who knows something about computers.
When i boot it up, when the hp logo comes up the screen is with vertical lines. After some searching this is probably a problem with the graphic card, but another problem is found. the next screen is made out of "!" it looks something like this

! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ....and so on the whole screen is filled with !
I will post up pictures when i get my camera

Another thing is that i go into the bios, it is also filled with the ! and also the letters are all wrong. it is like Start is spelled Stjht the letter A represented by J and the letter r represented with H. so it shows a different letter but its not random letters for all words, its like this on all words, the J being a for all words in the bios.
So then thinking its a corrupted bios, i ordered a new motherboard and replaced it. After a new motherboard, nothing changed. So what my father is thinking is that the motherboard we bought is corrupted just like the one i have. We bought this on ebay and the seller had multiple of the same motherboard for a low price of $70. So we asked the seller to give a working motherboard with some pictures of my corrupted bios and screen. (currently in my fathers computer that i cant access to) They replied that the motherboard has no problem and should try replacing my memory (if that even would fix anything) and the graphic card.
So i'm thinking of getting a new graphic card. If i am getting a new one, i'm probably get a better card then the current one, which is gonna cost $80-$150 or so. So before i do, might as well ask on this great site.
Thank you

ask for any more information, will put up the pictures tomorrow or soon.

You don't need to risk $80 -$150 to find out if the card is back. Just put some old $5-on-ebay PCI card in, boot up and see if the bios screen looks OK, If so, well, your old card is bad.

The HP screen
The Bios
The BIos
This is the screen right after the HP screen

Something i forgot to tell you, i can not boot up to windows. It goes to the bluescreen and restarts the computer, or sometimes it just stay with a black screen.
When i first foudn out about this, i could get into safemode. I scanned my computer for any viruses but nothing was found. So i tried reinstalling my OS and formatted my hard drive. After it is "finished" installing vista it has to restart and finsh from there but comes up with an error saying it could not install and tell me to restart and try again. I tired many times and wno i cant even go to safe mode since there is no working os installed.
again, ask for any more questions you need to help me
Thank you

Since it's showing up before the OS loads it's got to be a hardware problem. That hardware problem might be affecting your windows installation or maybe that's a separate issue. I googled "exclaimation marks" video screen -yellow and got a few hits with no precise solutions but general agreement it's a video card/controller problem.

Swap in another card. As mentioned above a cheapo one will be fine since you're just checking the bios/posting screen.

I'm saying it's probably the card. But I wouldn't buy a fancy new one without trying a a more basic, cheaper card first. The bios and posting screen don't care if your card is $5 or $200 and how it displays will be the best way of finding out if your old one is bad.
