I have a Biostar TZ77B mobo with an LGA 1155 socket, and I upgraded my ivy bridge i3-3220 to an i7-3770.
Afterwards, I turn on my computer and after the Biostar T-series splash screen, I get an American Megatrends screen that tells me that a new CPU has been detected, and I need to reset the motherboard to its defaults. Except I can't get into the bios/uefi using the prescribed <delete> keypress no matter how many times I try it.
Now, it must be said that the computer goes from this American Megatrends screen into Windows 10 and seems to work fine. It even registers the new cpu. Still, I try and try to reset to get into the bios/uefi to reset the mobo to the defaults.
Well, after getting some advice, I pull out the CMOS battery, which I'm told will reset the mobo defaults. After waiting a bit, I put it back in, it clicks firmly into place, BUT I'm still getting the American Megatrends screen telling that I need to reset to the mobo's defaults--which pulling the batter was supposed to accomplish--AND now I get a "cmos fail" message. Ugh.
I have to say, the computer still seems to work fine, it boots, loads the OS, etc., despite the problems.
What can I do? I'm at a loss. Any help would be greatly appreciated.
