Summary: I have built many PC's, some more successful than others but all have worked. I must say though, this is by far the worst, I don't know how it got decent reviews?? Lost hard Drive Mapping, Impossible to get the Sound to work consistantly, yes I downloaded and installed the latest drivers from ASRock. Front side USB ports not working at all, Rear USB drops devices at will. I've been had on this one. Buy something else.
Summary: The good part is that the board worked out of the box. The bad part is, for the price, it doesn't have enough of anything. This is a cheap board. Don't pay $90 for it like I did. I'm kicking myself for that. There are only two memory slots, there are enough USB ports, but you have to buy a back panel to access the last two, as they don't supply one. Plus there is a weirdness with some of the USB ports so that they won't work with a hub.
Summary: No problem. It works just like it should. The only problem is it is a 32bit board in an increasingly-64bit world. I recommend the buyer consider upgrading to a 64bit system. But, if cost is the only consideration, this one works well.
