|"...its a desktop pc with the card slots built into the front of the case. It was like that when I bought it. Is this a problem? "|
It can be. Sometimes the wiring between the card slot(s) circuits and the USB header it connects to on the mboard is inadequate, more likely if it's an el-cheapo case.
(The same may apply to wiring for front USB ports, especially if they're further up on a tower case rather than near the bottom, and the USB ports farther up may actually be a multiple port USB hub connected to the pins for only one USB port on the mboard USB header, rather than each USB port being connected to the pins for one USB port on the mboard header, as most front USB ports near the bottom are.)
Do you have other memory cards that you're supposed to be able to read in the front slots ? E.g. (a) card(s) used in a digital camera.
If you do, does it / do they read properly ?
If it does / they do, then there's nothing wrong with the wiring.
If you unplugged the card while Windows was running without clicking on the Safely Remove Hardware icon, and STOPping accessing the drive, you may have damaged data on the card.
In any case, you may need to repair data damage on the card by using a program meant for that.

By the way, what is the 32gb memory card meant to be used for - what is printed on it ?
Some memory cards meant to be used in certain models of certain camera brands are partitioned and formatted an oddball way. E.g. some cards meant to be used in some Olympus models.
They read okay in the operating system if the partitioning / formatting hasn't been messed with, but if you format them in the operating system, you get an oddball result. You're only supposed to format them using certain camera model's built in format program.
E.g. Olympus Smart Media cards.
Mend your SmartMedia card and make it Olympus Panoramic compatible
If your SmartMedia card doesn't work in your Olympus camera anymore then it's probably because you used your PC to delete some files off it, to write to it, or to format it. Sometimes the formatting gets corrupted if you didn't dismount the card correctly too
Not sure if this works for all but.......I formatted my burnt SM cards in my PoGo Ripflash MP3 player, put the card back in my camera and boom...they work again. Still a huge pain but at least its portable
