I had Windows Vista Home Basic (My computer is a Dell) and I was going to reformat because of a bad virus. My bro gave me Vista Home Premium so i used that and started the formatting process. When it finished, i played a game of solitaire and a notice came up saying that hardware acceleration is off (never happened before). When the game opened, the frame rate becomes very low. Im assuming that my graphics card isn’t working properly. I ran DirectX Diagnostics and it didnt detect my graphics card.
I ran Everest and it says that the graphics card is a Standard VGA (if memory serves from 30mins ago).

I bought this computer off ebay a while ago and the seller gave me the following Installation CDs:

o Cyberlink PowerDVD
o Dell Photo All-in-One Printer
o Dell Dimension Computer Software
o Windows Vista Home Basic 32bit
o Dell LCD Flat Panel Monitor
o Norton Anitvirus

I installed them all except the antivirus.

When I opened up my computer (risky for a noob like me :D), I saw three cards (i assumed one was a graphics CARD). I unclipped them and one says Dell Memory and the others have no name. Games were working for me earlier before i uprgraded.

How do i find the graphics card so i can update it?
Is there any other ways to fix this?

Help please ~ ty
