Can you get into the bios, if you can load, most call it (load fail safe defaults) then see if it will boot

 

[sjtangb21]

yes. i just call the gigabyte they told me the same thing, I am going to try it tonight, if it doesn't work I will keep you updated!

A failing PSU and a bad battery can cause this problem.

I thought that too, but since it was fine till he starting messin with his voltage, thought he might have something screwed in the bios!

 

[sjtangb21]

my psu is good, brand new, and the so is the mother board, not even a month old

if you reset the bios,,and the error is displayed again try to replace some backup-battery,maybe it is damage,,thats all....khajeff

its pretty common the Pc gives the CMOS checksum error when you resetted the bios using the jumper or by popping the battery out,. just enter the bios, save settings, and reboot.
