Windows 7 and USB 3.0 Problems

New to this forum. Not a techie for sure. Just a PC user. I think this site comes as close as anything I've found for helping with my problem. Namely, a Windows 7 64 bit PC with USB 3.0 external devices attached that slows down and then crashes ... then, will not relaunch (even with a boot disc) until I unplug all the 3.0 USB external devices. Then it relaunches fine and I re-plug the USB 3.0 devices and all is well for a while. But, eventually the crash comes again and the process starts all over again. If I read the dialogue right in this sequence, it looks like I need to "install the USB 3.0 (ex. chipset) drivers from the manufacturers site for USB 3.0". My only problem is that this is not a consumer-made PC. It was hand-built by a friend. So, my questions are (1) Which manufacturer part of this PC (motherboard, video card, or what) do I need to get the "chipset" from? and (2) Am I correct in that it looks like a "chipset" is something that I'll need to physically install somewhere in this PC when I get it? Thanks folks. Sorry to be so dumb on this stuff.

Thxs for quick reply. Found BOM of PC, and for Motherboard it reads "ASUS P8P67 PRO LGA 1155 SATA 6Gbps and USB 3.0 Supported Intel P67 DDR3 2400 ATX Motherboard". Hummm, with that "3.0 Supported" in the description, does that mean it should already be able to handle USB 3.0? And, the problem is somewhere else?

Thanks again Brink.

The quickness and detailed help is unlike anything I've found on such sites as this before. I will get the drivers.

Meanwhile, I have found that plugging the 3.0 external devices directly into the PC (taking the hubs out of the hookup) has significantly helped the access speed to information saved on the external drives.

I don't know where those little award medals come from. But, I'd award ya one if I could find 'em.

Brink, I just now got around to installing the downloads you told me would fix my problem. But, I can't figure out what to click on after I got them downloaded. I extracted the zipped files and then open them and there are lines and lines and lines of things that I have no idea what they are. I "think" I need to use the one that says, "Asus setup". But, I'm not sure. Sorry to be so PC-illiterate.
