Changed ASUS mobo battery now can't get into the BIOS

Hi

Last Tuesday I rebooted to go into Windows 10 and that is the last time my PC was up and running. All I had until two days ago was a black screen when my husband suggested I change the battery on my mobo (ASUS Z97-K) which I did. Since then I do get a display come up telling me to press DEL or F2 to enter the UEFI BIOS but neither key does a thing and it doesn't make any difference whether I press and hold whilst booting or not - the BIOS still doesn't appear.

It is true to say that I have had the battery for a very long time although the expiry date is July 2018. I also have three different types of keyboard, a PS2, a wireless and since yesterday a USB keyboard. However, none have had any effect on entering the BIOS. I'm sure there has to be a way of entering the BIOS somehow or other. If I could just get into the BIOS I feel certain I could possibly be up and running within a short space of time but I just can't get into the BIOS and the ASUS forum is not proving to be a lot of good at present. Does anyone have any possible suggestions as to where I go from here?

With the keyboard I received yesterday, I also received a Gigabyte Z97P-D3 mobo as currently I'm not over impressed with ASUS mobos and their customer service and I 'm seriously considering changing the mobo for the Gigabyte in order to get up and running but I don't really know what caused my problem in the first place. What would people advise? Any help would be most appreciated. Thanks.

Two days ago you had a black screen.
- Was the fans running?

Today
- Do you still have a black screen? Are the graphics card fans running?
- Is it only the black screen or it seems completely dead?
- Is your mouse and keyboard attached to USB 2.0 and not to a USB 3.0?

- MB battery (CR2032) should last more than 5 years.
- Changing battery does a BIOS config reset and all BIOS settings must be reconfigured.

Did you checked the power supply?

I have a Gigabyte MB and I think Asus is a better brand.

Hi
Thanks for your responses and yes, I have tried clearing the CMOS, TWICE. However, all to no avail. Snag is I don't really know enough above the boot process and although I've got another new Gigabyte mobo I'm reluctant to install it as I don't know what has gone wrong or caused the current problem and I don't want to damage another new board. I'm on the point of calling in the pros. Yes, its going to cost more money but I feel that is the best way forward at present as something like this scares the living daylights out of me.

I also put a message up on the ASUS forum and someone suggested I could do a DOS flash of my BIOS with a new version but I have grave doubts about that since I get nothing other than a graphic telling me to press DEL or F2 neither of which do a thing. Its my opinion that the PC is not entering the POST tests which at its worst could mean a blown processor (God forbid) as a new one will cost something around £260 - but I guess it could mean several other things as well. So I shall be contacting the pros to see what they can do to help.

Again thanks for your responses but I feel happier with my decision to let the pros see what they can do.

If your mouse and keyboard are on a USB 3 socket they won't work.
They MUST be on a USB 2.0 socket.
