How do I fix my USB that it doesn't detect anything at all

[Andy8533]

Hi. I'm new to this forum and it's my first post. Recently im having problem with my pc.
These few days my pc start not to behave normally. Sometimes it just will hang suddenly. And now I have a clean install window 7 home premium 64 bit and now I'm stuck with the set up window part becaus it won't detect any USB port at all. I tried to insert all USB port to see if it can detect my mouse or keyboard. I've tried it on another pc and it works fine. I really need help. My pc now is like without hand and leg but only body.
This is my pc spec

intel core i5-2500k,gigabyte z68ap-d3 mainboard,asus gtx550 graphic card,kingston ddr3 4gb ram,500gb sata harddisk,cooler master 500w power supply,coolermaster glite 310 casing,lg dvd writer

You're saying it doesn't detect any USB port. Is that because when you try to use a keyboard or mouse, you see no response on the screen?

If so, couple of things you could try:
1) If your motherboard has both USB 3.0 ports and USB 2.0 ports, make sure the keyboard and mouse are BOTH plugged into the USB 2.0 ports.
2) Go into your BIOS settings and see if you have an option to enable or disable legacy mode. If you have that option and legacy mode is disabled, then enable it and try again.

Hi,

I would also suggest you to do Flee Power, remove any 3rd party peripherals and power cord from your Desktop, press and hold the power button for 20 seconds to discharge any residual current inside the desktop.
