i have a weird problem with my usb ports. so my usb work only on my mouse, keyboard, and wireless adapter, but besides those things nothing works. for example, flash drive, and external hard drive does not work.

It could be a power issue - insufficient power available from the USB ports when several other USB devices are already plugged in and using power.

That can be fixed by buying a Mains-powered USB Hub. You plug that into a mains power socket with the supplied a/c adapter, then plug it into a USB port, then plug your flash drive and external hard drive into the ports on the hub.

here's an example of a Mains-powered USB Hub: http://www.amazon.co.uk/Port-Mains-Power-Supply-Cable/dp/B000J3WE0W

I think it is a power issue. My power supply only have 650w and it's a kingwin. And I have a GeForce gtx 460 v2
