[Oscar200000000]

Hi , i have just made my first build

Asus sabertooth 990fx r2.0 motherboard

2x4gb corsair ram
40gb Intel ssd
1tb/32mb
Amd fx 4100 3.6ghz cpu
Evga nvidia GeForce 780ti 3gb
750w corsair cxm power supply

I have checked compatibility and everything is fine

So I power it up after installing every thing (the components) and I am getting ready to install Windows 10 64bit , it says on the screen press F2 or DEL to enter bios , but it won't let me type anything I have tried numerous keyboards

I have taken out the cmos battery
I have tried all of the USB ports
I have tried numerous keyboards

Thanks in advance
I need this work soon!

Hi, Try leaving single RAM module installed. Test each slot.
If still no go. try testing different RAM.

then I'd RMA both motherboard and CPU.

Hi what is RMA?

Returning the product under warranty, for repair, or replacement.

Hi thanks for the reply

You don't think it could be anything else ? I don't particularly want to return them

Oh and the boot led is lit

You're welcome. Then try rebuilding the system outside the case, Check the CPU if any bent pin. If still no go...

Can you grab a USB flash drive that is formatted as fat32 and get the latest BIOS from here. Recommended that it will be the only file on the drive.

https://www.asus.com/us/Motherboards/SABERTOOTH_990FX_R20/HelpDesk_Download/

Get this one SABERTOOTH 990FX R2.0 BIOS 2501

Open the zip file and drag the file SABERTOOTH-990FX-R20-ASUS-2501.CAP to the USB flash drive.

Then plug the flash drive into the FLASH BACK USB port its circled in green and press the Flash Back button.

Wait 10 mins until the FLASHBACK light stops blinking. If the light stops blinking right away rename the file to 990FXR20.CAP

I believe your BIOS is out of date can cause a pc that will not POST.


Then remove Flash drive and power on system.

Make sure you also have the 8 Pin Power connector near the CPU plugged in or it will not boot.

If it refuses to POST or BOOT to bios. Power off the System. Try using the MemOK button near the memory slots. It will auto set the Memory timings that will allow the system to POST. The DRAM LED light will blink the system will power up and it will right into BIOS to allow you to save settings.

If that does not work its possible you got a defective board and need to RMA the board at this point.
