Posted May 28, 2020 Memory is not agreeing with what you are trying to run it at. That is all. Wih mismatched sticks it is best to leave it on auto settings. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

Or alternatively you can unplug the PC power cord take out the CR2032 CMOS battery for around 10 or so minutes. Clearing the CMOS resets all of your BIOS settings back to default and should allow the system to POST again.

Posted May 30, 2020 just try this; remove both [or all] ram sticks, save config, reboot...hopefully you will get an error beep indicating no memory detected...then replace the #1 stick and retry...all you can do is hope! If you are sure you have reset the BIOS to default settings [by removing the cmos battery and power lead, and shorting the clear cmos pins; then do that again...maybe you will get lucky with that. Are you certain you never changed any other settings? Thou if you've cleared the cmos...it SHOULD boot to the bios screen...have phun! Link to comment Share on other sites More sharing options...
