Which ones did you buy? Could you have tried to install them wrong side up? When installed in an ATX form factor case and motherboard, the cards hang upside down. If that wasn't it, in what way did it not fit?

honestly,one of my friends who's a bit of a computer wizz bought them for me and he himself was shocked when neither worked when he tried to install them)(sorry i don't remember their names)the AGP one and according to what he said my computer didn't have enough power to run and the pci one did not fit physically into the slot.

Depending on which AGP card you got, that could be true. But what about getting a new power supply? I'm not familiar with Sonys so I don't know if they can take a standard ATX power supply.

I don't know why a PCI card wouldn't fit into a PCI slot unless there was some physical interference with some other component. It's just as well in a way because if you have an AGP slot, you should try to get an AGP card. They are so much better than PCI graphics cards.

But without more details, I'm not sure what to tell you.

Sounds to me like your friend was trying to put a PCI-express card into a PCI slot. http://www.directron.com/expressguide.html

Having only a 300Watt power supply does limit the upgrade possibilities. You could always buy a new Power supply though (~$60)--they are really easy to install. http://www.fonerbooks.com/r_power.htm
An as for it being an ATX power supply..you can always open up your computer case and look on the side of the power supply. It should say something like Blah Blah 300W ATX.

For an upgrade I would recommend a 6600 (~$100) at least. Here is the card that I have...
