Hi all,

I have windows 7 installed on a ssd, and the boot time is quick! however Im wondering if its too quick, as the lights on the keyboard dont come on until im into windows, so I cant access the bios, I bought a cheap keyboard to make sure my ms sidewinder x4 wasnt broke.

Any suggestions?
 
have you tried pushing F1, F2, or F10. Delete, Esc in continuous strokes right after hitting the power button on the computer?

Have you tried moving the keyboard to a different port on the motherboard?

Once you get into the BIOS/CMOS/UEFI

Set a Delay of 5 seconds For the motherboard POST/Splash Screen. I had to do that to my bros machine because it booted too fast
 
tap quicker lol

Just unplug your hard drive and it will give you a option. <<
 
The system is not recognising any usb devices. every now and again my cpu fan drops below 600rpm so I get a "cpu fan error" message, I could get into the bios from here, but on this screen it says there is no mouse or keyboard connected, they are only recognised once into the os?

Did a bios update recently but was able to get to the bios after that.
 
If you have a USB keyboard, there is a good chance that your bios is not set to recognize USB / USB legacy devices straight from boot.

Some motherboards DON'T recognize USB keyboards by default unless told to.

Take a look a the back of your PC , if your board also has an older PS/2 keyboard connector - try and borrow one from somewhere and plug it in - there is a good chance that the PS/2 keyboard will be able to get you into your BIOS where you can enable USB keyboard recognition.

The sabertooth doesnt have any legacy ports
 
My only other thought then is , is it a wireless USB ? because some of those (even a few Microsoft branded ones I have used) don't work at all before windows loads as the USB dongle is semi software emulated.

Other than that I have no idea.

EDIT : Looks like a combo legacy connector to me ... :3

I also have an ASUS board and I know mine defaults to DISABLED USB keyboard at boot if I default it.

ya that board has no PS2 ports on it, shameful on asus
 
Its a microsoft wired x4,

Have been debating wether or not to flash bios again and see if that refreshes the settings, must have knocked the wrong settings on when optimising boot settings. :banghead:
 
I dont really like flashing boards though, had a bad experience so this seems like quite a trivial thing to block the board up for :o
 
Perhaps there might be a way to get in via the Management Engine Interface in windows?

I'll be honest I deal mostly with office type systems apart from my own machine, so I've not yet played with this board, but these new BIOS occasionally have some kind of windows interface - might help?

See Management Engine Interface under Utilities?

Is the USB keyboard connected to the USB 3.0 port? Try to connect tor USB2.0

I had trouble getting into my Bros AsRock 970 Pro after the first boot, thats how fast it was booting, thats when i set a 5 second boot for the splash screen

As a general reply to anyone reading this thread - this is also very good advice - plugging your keyboard or mouse into a USB3 port can make it unavailable to many early USB3 adopting motherboard BOIS'es but beyond that it is a TOTAL WASTE of a USB3 port.

USB3 ports deliver higher than average power and FAR greater data speeds than previous ports and the idea here really is for connecting data devices, such as flash drives, printer/scanners, external storage, or disc reader/writers, and so on.

The data and power required by most mice and keyboards can be HUNDREDS of times less than what a USB3 Port provides, and using one up for a keyboard its a total waste of resource, apart from also causing potential complications outside of the OS.

If you have USB3 port's they are usually identifiable by their blue coloring.

Id say signal issues occur because of the extra pins in USB 3.0

I had originally thought this was to be the case, but I have tried all usb ports on the system, including front panel(something stupid like 13!) to no avail :banghead:
 
only other thing i can recommend is to CLEAR CMOS at this point
 
Sometime I have had problem with new systems using USB to get into the bios. Thats why i keep a PS2 keyboard around. After a couple of boots it seam to go away and is fine.

Dude The board he has does not have any PS2 ports on it, when a PS2 keyboard has a USB adapter used the signalling is that of USB
 
i have exactly the same problem, it only refuse to function on 2 gaming keyboards brand other keyboard works fine, trying everything without success and finally contact MSI (my board manufacturer) and they told me it is a BIOS compatibility problem and they send me new bios that supposed to fix the problem but unfortunately the new bios still didn't work on 1 of the keyboard, report back the result to MSI and i still didn't receive any answer from them.

Unfortunatley I have tried several keyboard brands and none work, I think you maybe onto something with bios issues, As I have recently flashed the bios, but it worked after the upgrade, then has suddenly stopped working.

if you can, Id recommend a BIOS/CMOS Reset via the jumper on the board. If in event that doesnt work, either Return the board for an AsRock or other company or RMA it to Asus.
