It Doesnt Recognize the SD/MMC

[Irving]

I have a Compac Presario Desktop Computer.
To be more specific, its like almost all Compaq pc's, hehe.
Black, with the cd driver,below all the card slots, like SmartMedia,CompactFlash,SD,Memory Stick and a USB Port.

Ok,the problem is that it doesnt recognize when i insert the SD card of my camera to the SD Slot.And i thought that it didnt work nothing of there,but yesterday i inserted a Memory stick card and it loaded easily.
And I again tried with other SD Cards,and nothing.
When i bought the PC, I formatted all data,like my laptop, cause normally it have a loot of trash programs,that i dont use.And i had some problems finding some of the drivers.And im sure that it worked when i purchased it.

What can be the solution?Another driver?And if yes,what type of driver should i search?Cause i dont think that is damaged or something like that.
And for all people that are about to say:
"JUST BUY A USB-SD CARD ADAPTER",dont say it,if i search help here,is cause i want to fix this. So please, dont say things like that.

Thanks for your attention.

EDIT:when i insert the SD Card it only turns on a green light in the left side of the slot. :)

What's your full name of the PC?
Just saying Compaq Presario is like saying Sony Vaio :D

The green light is just a card in indicator, you say not recognised - what happens when you try and access it as a disk drive, does your camera have a native format for the cards that require an app to view them?

Compaq Presario SR2017CL

And Decker,I cant access it as a disk drive,it doesnt appear in the list, and to be honest i dont know if it requires a special software to load the photos.
Its a Polaroid i733.

Thanks in advance.
