Im having problems with my USB ports not working at all. Anything I try to plug into them doesnt work, except for this one PNY 1GB flashdrive. not even my external hard drive, or a mouse, or a keyboard or anything. I dont know if what I need is to update drivers or what, but it baffles me that one flashdrive will work, but lots of other things wont. much appreciation to anyone that can help me.
