I have an Asus z97-p motherboard. It works fine but if I try to make any bios settings changes, it won't boot. In order to make it boot I need to reset it with the jumper, then when the setup screen appears (after pressing f1... etc) if I exit without saving anything it boots and it works without any problems.

I tried replacing the CMOS battery. I tried two different brands, didn't work. :(

Anyone familiar with this problem? I can't find any equivalent motherboards where I live. Only available ones are H81s. I'd like to fix my motherboard if it's possible.
