Hey guys, my uncle has a homebuilt computer with an ECS Elite Group motherboard...and it says it's usb 2.0..but when we plug in any usb 2.0 CF card reader..it will work fine for about 1/2 hour..then the USB function will stop working completely until we restart the computer...could a bios flash upgrade help this problem? or does it sound like a faulty motherboard...also..we have reinstalled the OS multiple times to no avail..thanks for the help...i owe yall one
