3 problems someone please help

i built my first comp the other day and loaded windows and well i have 3 problems.

1st. i can't get sound. it won't let me install the audio drivers for the mobo. something about hda or hdd(can't remember which one. at work now) missing cannot find. anyone know how to fix that.

2nd. it won't let me install usb 2.0 drivers. saying windows xp supports it but when i plug usb in it says it's not in highspeed port.

3rd. i had bought a 250gb hd. for some reason it's only saying i have 127gb.

Devils in the details. What motherboard? Windows XP I assume. BIOS version plz. Processer? RAM and video? Anthing in the PCI slots?

- Yeah thats problems 2 and 3 right there. 2000 does not support USB2 or drives larger than 127GB. Upgrade to XP Service Pack 2 and those problems will disappear. It might help with problem 1 too. Upgrade to SP2 and post back your results.

Use PM or post here again.

Thank you very much. i went and bought a REAL version of windows with sp2 and it seemed like sp2 did the trick. everthing is running perfectly. now if i can just find a way to keep my mobo from going up to 70 C and processor to 60 C without opening the case and putting a big fan on it that would be perfect.
