What hard drives fit compaq-presario

Presario what? (there's a sh*t lot of Compaq's with the Presario name).

presario what....huh?..Im not too bright. model kj393aa-aba sr5413wm. Vista, AMD athlon le 1640, 2700 Mhz, 1 core.......mean anything....?

Any 3.5 inch drive will run fine in it, as for sound card, on board audio is more then enough, depends on your motherboard chipset.
As for western digital, look at the black and blue series

Check first your casing if it can accommodate the hard disk and the audio card in it. Next check if you still have a power cable for the HD and data cable.

My budget would be around 1-200 bills. i'd also like to add more memory. Do I buy two cards at a time? What are the notable memory cards. Tanks for all the answers everyone.

One more if you have time? My video card has HDMI, DVI, and vga outpit. The manual tells me to hook the HDMI to the DVI outpt (w/ an adapter) to have real HDMI. If this is the case, what is the point of the HDMI outpui? Thanks Again, Sean

With $200 you can get a 1.5TB WD drive and 4GB of DDR2 800 with change to spare.

Yes, HDMI and DVI output the same video signal.
The only difference is that HDMI is capable of carrying an audio signal along with the video.
Using a DVI => HDMI adapter will output the exact same digital video signal just without the sound (unless you have a newer ATI GPU).

As your newer GPU already has an HDMI output, I would recommend using it.
IDK why the manual recommends using the DVI => HDMI adapter.
Perhaps the same manual covers several similar cards, some of which lack the dedicated HDMI port.
