i was wondering how do you check if you have a PCI or AGP graphics card slot because im interested in getting a graphics card but im still so confused over this matter. i have a Presario S4200NX if that helps, or can someone aid me in how to check?

I have googled your PC and i'm not sure that your PC does have an AGP slot. The 4300 does, but not the 4000 or 4200... Its either time for a new Motherboard, an new PC or one of those nasty PCI (NOT PCI-e/PCI-EXPRESS) graphics cards... You would need to decide what sort of games you want to play, your Celeron processor is very poor for gaming from the outset. The Cheapest Option would be to buy a PCI graphics card like a Radeon 9250 or Geforce 5200 The most expensive option would be to buy a whole new PC. The value for money option would be to buy a new processor, motherboard and graphics card (either AGP or PCI Express, preferably PCI Express).

From was I was able to find by googling your model number, your board is an Asus P4G533-LA/P4G533-GL (aka ECHO). It has PCI slots only. One sure way to find out would be to open the case & have a look. I wouldn't spend any more than this: http://www.newegg.com/Product/Produ...

The best you can do with PCI is an ATI Radeon X1550, but those gpu's are around 100 dollars right now, and that would be overkill for your pc considering your cpu is the bottleneck.
