Just finished my first build. My motherboard is an AsRock Z77 Extreme 3. I got it to recognize a keyboard after everything as put together but I did not have Windows yet. Picked up Windows today but now it will not recognize any keyboard, ps/2or USB. Cannot get into BIOS to change legacy settings cannot load Windows. it is stuck on AsRock Post screen. I could use some help. Checked to make sure the other keyboards work already. The lights flash when the new System powers on, but thats it. Thanks in advance for the help.
When we plug the keyboard into ps/2 socket it flashes showing its getting power, but will not let us use the keyboard. Right now we have only memory, video card, GPU and CPU running so its bare minimum off of motherboard still nothing. Have also reset CMOS.
Yes, and it saved correct date and time. Put in Win 7 disc to install and restarted system and optical drive starts to spin then stops, will not register keyboard again to get back into BIOS to see if there is an issue there. Even tried plugging in a USB mouse to se if there was no power to the ports on the mobo, strangely, the mouse has power even with the system not powered on. Tried to disassemble completely, pull battery from mobo and jumper CMOS again which is how we got it to reset yesterday, all to no avail. Still have to hold down power button to power off, so something is holding memory. Am getting very frustrated. No beeps through in case speaker at power on, tried to swap out SATA and cables...nothing. I am still stuck on AsRock post screen.
Wondering if maybe we have received a faulty optical drive and if we could pull the optical drive from my boyfriends recent build to get This one up and running with Windows installed until we can get the drive replaced. Would a bad drive maybe cause these problems if BIOS is set to boot from it?
Not sure if it is the motherboard... The problem ATM is not being able to reset BIOS. Got it to reset once by jumper'ing CMOS and removing battery from mobo. That process will not work now. Any ideas on an alternate method?
