my motherboard is ASUS Z97-A and recently I used Dual Intelligent Processors 5 to auto overclock my CPU.

However, I accidentally updated BIOS without resetting the clock after I overclocked it. Now I cannot boot to the OS and a message that goes "Initializing Intel Boot Agent GE v1.5.47 PXE 2.1 Build 092 (WfM 2.0)" keep showing up when I turn my computer on.

I've tried to clear CMOS by removing the battery and moving the jumper, but none of them worked for me.

Anyone can help? Thanks in advance!

you just have keep rebooting and pressing the del key over and over until you catch the 1 or 2 second window where it will work.

-you might be able make a hardware change that will force the BIOS to be entered (error)

-see page 1-23 of the motherboard user manual
you can use the pins to clear the Real Time Clock and stored setup parameters. Then when you power on, it should boot into BIOS or give a error and wait for you to enter BIOS

the message indicates that the BIOS attempting to boot the machine with a network boot image and can not find it.

You really need to get into BIOS and reconfigure your machine to make the boot device your drive where your OS is installed.

here is the sequence that your system is running:
Power on –> BIOS –> Network Card PXE stack –> Network Boot Program (downloaded from server that you don't have)
you need to break into the BIOS before control is passed to the network card.

Thanks for answering! How do I break into the BIOS? my computer indicate me pressing F2 or DEL to get into BIOS. I've tried both but none of them worked. Also when I excessively pressed DEL the computer turned off.
