I have to reset Cmos after every boot

post #1 of 25

Why.
lol.
Is it the battery?
or stubborn overclocks?
It boot up ONCE.
AND ONLY ONCE.
I was holding the power button to turn it back off when the bios screen popped up.

I started to have a similar problem on my board. I've tested a beta Bios (huge mistake!) and it all started afterwards.

I've changed the BIOS to various verified version but still the same. Everytime after restart/ new start, the PC just doesn't boot (it checks the HDD though).

I have to manually reset CMOS and only SOMETIMES it boots. 50% of the successful boots, it crashes during the windows loading screen and I have to reset CMOS again.

It might have to do with low battery but I was expecting it to reload itself, which isn't happening.

2 months till my warranty is over, going to give mine to warranty and buy a Bulldozer compatible board meanwhile.

Really sucks alot lol.
I'm always locking my account instead of turning off the computer cause of that.
And it's a real pain cause if you leave the power plugged in it doesn't boot, and sometimes I forget.

Just bought this board like 3 days ago though!

Could be the battery. In Bios, check the cmos voltage. should be right arond 3v, and anything below 2.5 can cause problems. (1.8v and lower means change it asap)
(speedfan can show you this value as well)

i would go with unstable memory.
i had pretty much the same thing and it was due to the fsb only overclock,the only way round it was to leave the computer on and set the STR time to 5 minutes of inactivity,oddly enough i would lose the fsb overclock but keep the northbridge overclock doing this-so i didnt even notice that the cpu was running at 1078x4!
if it happens at stock clock did you buy the mobo second hand?

Vbat is right. And that's normal voltage.

Something (a voltage value possibly) is set up incorrectly in bios.
Could even be a ram issue. Maybe you have the dimms in the wrong slots.

Try resetting bios (shut down pc, disconnect psu, remove cmos battery, hold power button down for 5 seconds, replace cmos battery, plug in and turn pc on)
