Biostar TZ77XE3 can't enter bios (CMOS fail)
Last response: in Motherboards
Hi,
So I just recently replaced my Gigabyte Z68X-UD3H-B3 with a Biostar TZ77XE3 because the former had boot loop issues. I didn't reinstall windows, and when I power up the machine, after the splash screen it says "CPU changed. Enter BIOS setup by pressing DEL" (something along those lines), and then under that it says "CMOS fail, press DEL to enter BIOS".
During this time, pressing DEL does nothing. After this screen dissapears, Windows 7 boots normally.
It is just an inconvenience not being able to enter BIOS, how do I fix this? Thanks

Look the previous mobo was a z68 whereas this one is a z77.anyway you better first check for the cmos jumper for at least entering the bios. replace the jumper from 1-2 to 2-3 keep for 30-40 secs and replace it to previous position.be sure to do this with power off.then let us know whether you can get in the bios....

Is it safe to do so, or can it make my Windows inaccessible? As of yet, even though I can't access the bios, Windows runs pretty much perfectly after it boots. I wouldn't want it to not be able to boot into Windows after the reset.

Coming to your question...look out for the rightmost end of your mainboard ..there should be 2 jumpers..each only covering 2 of the 3 pins.Do what i said before to the upper jumper.
Understanding from my reply if becomes difficult or you do not find the jumpers in the position i said (mAYBE in some mainboard) google search the topic 'cmos jumper replacement' and you will get lots of visual ideas....Let us know if you are succesful in entering bios.
