I updated my motherboards (a XFX 750a sli) BIOS, v1.7 from the ISO file from their site. Flashed the BIOS, said it was complete. Restarted.
Now when I start, I get CMOS checksum bad. And CMOS date / time not set.
I can F1 into Set up, Set date/ time, Exit and save. Then it just hanges and does not boot up.
I reset the CMOS,with jumpers, but everytime I restart the PC I get the error.
I tried to reflash with a different download, but get the same results.
If i use the CMOS reset button on MOBO then i am able to load the default settings from NVRAM to get system started. But if I shut down and restart it will not load again, until I press the CMOS reset again.
I am not running SLI , not OC the cpu or mem.running a 9800GTX and all my settings in the BIOS look normal as far as I can tell.
