My asus m5a97 le r2.0 freezes at the prompt to open bios when usb devices are being used.

I have to unplug the keyboard and mouse to get it to boot. It restarts fine with usb devices unless I put one in the 3.0 instead of 2.0.

I have an AMD FX-6300; Sapphire radeon hd 7870xt;Patriot Viper 3 Series Venom Red DDR3 8GB 1866MHz that the motherboard recognizes as 1600mhz and I occasionally get BSOD when I set it to 1866MHz manually.

I flashed to bios 1706 before installing windows 7. Tomorrow I am thinking of down flashing to bios 1506 which is what it was before. Also moving the memory into different slots.

The most annoying thing is the usb problem. I believe i will have to RMA it. Other than that it runs fine.

Any suggestions?

Mouse and keyboard are for the usb2 ports.

ASMedia® USB 3.0 controller : 2 x USB 3.0/2.0 port(s) (2 at back panel, blue)
The Asmedia ports USB 3 are for external hdd's and not to be used with other devices

Any ram over and above 1333mhz must be XMP profile and the option for XMP enabled in the bios.

Edit -
Your ram is XMP 1.3 compliant -
ram specs


Edit2 -
The FX-5300 is not listed in the CPU support list, not that I can see -

It's the FX-6300 and it recognizes it. And the system runs great except for this booting problem.

FX 6300, dang, I thought I had it solved. :(

It's a UEFI bios, there might be a key option at boot up as to whether you enter UEFI or regular bios or select the boot options menu for the UEFI.

"Press F2 to enter setup" - "Setup" is the bios.

Edit - Hang on, if the mouse and keyboard are preventing boot up then that could infer an under powered PSU, you'd need about 550 watts PSU, assumedly, depending on the other hardware...

What are all your hardware, anyhow and the PSU?

Edit 3- why don't you leave the mouse and keyboard in usb 2.0 ports if they work there? Why do you sometimes inadvertently put them into usb 3.0? Why is there such a need to remove them once they are in place (usb2.0)?

What else do you have connected to the other ports? external hdd? Remove it. You don't need it connected to boot up to desktop.

My PSU is a Thermaltake TR2 TR-600 600W ATX12V v2.3 SLI Ready CrossFire Ready Power Supply . I have no external drives. 1 internal 1tb 7200rpm hdd and one sata dvd burner.

I only need to remove them from usb 2.0 when the system has been powered off and I try to turn it on. It will restart with usbs in the 2.0, but it will not start with usb 2.0 if the system was powered off before booting.

If the mouse and/or keyboard are not standard but are Razer model or some such, you may need to utilize one USB 3.0 port (keyboard) and one USB 2.0 port (mouse) but depending on which device is actually compliant with USB 3 port, if both then better for keyboard in USB 3.0 and the mouse in USB 2.0 port but not both in usb 3.0 ports.
