usb ports have stopped working

Well i found the problem. A: im an idiot and B: those two usb ports that werent working were those 4 prong outlets, and 1 or 2 of the prongs in each was kinda bent and squished down.

my headset and wireless mouse receiver wouldnt plug into the other usb outlets, that have just the one bar, because there was this stupid little plastic thing inside their plug blocking it, which i was able to pry out, and they work fine in the other usb outlets. ( i was wondering why only two out of the 9 outlets i have would fit my hardware). I also didnt bother trying my ipod in one of the regular outlets, thinkin it wouldnt fit if the other ones didnt, until today and realized that it fit and worked fine in those outlets.

sorry for wasting your time. but i honestly bet some of the other people posting in these forums are dealing with the same problem.

Dont worry every ones an idiot at some time - good to see you solved your problem thats the main thing, and you live to fight another day :).

After reinstalling Win7 and having cleared Cmos my mouse/keyboard problems were gone.
thanks to all who tried to help!

greatz

too bad, i thought my usb problems were gone, but after some time it started all over again.
maybe my keyboard/mouse are both broken.

I doubt if its hardware

i found out what my problem was. it's the damn drivers.
i removed all concerning drivers and pluged in my mouse/keyboard again.
plug & play installed the basic drivers and my problems were gone.

if it will work for you guys, i don't know.
but, you'll see...

greatz & thanks for all help
