Standard VGA Graphics Adapter Help.....

Hello, this is my first post here :P I need some help. I play minecraft, before i installed windows 7, i used windows XP (My computer was originally designed for XP) I could play minecraft fine, but now it says "Bad Video Card Drives!" It told me to update them, it's already up to date it told me. I have no idea what i can do to fix this.... i think i had something like intel graphic cards before updating, but i'm not 100% sure. If someone can help me, that would be great. I Really miss killing creepers in minecraft :P

CPU: Intel(R) Pentium(R) 4 CPU 2.80GHz
Motherboard: Hewlett-Packard 09E8h
BIOS: Default System BIOS
1.00 GB Memory
HDD: SAMSUNG SP2504C ATA Device
Sound Card:Realtek AC'97 Audio

I don't really know anything about computers, just sayin :P Also, my computer is pretty old. But i know 100% that it does work with games like minecraft

I'm using a desktop :P

I checked the intel website and it looks like they don't support any old graphic cards for windows 7.......... but like i said, i'm not 100% sure that i used intel

That just leads to OpenGL. I'm pretty sure i need a good Graphic card to use it first anyway :P
