Computer forgetting date and losing CMOS settings on reboot - not MB battery.

MikeHunt79 · 1 Sep 2009 at 23:57

First up, specs:

Gigabyte p965 ds3 motherboard, rev 3.3, with BIOS F13
e5300 at 3.5GHz with 1.3875 vcore (BIOS)
4gb of RAM - 2x2gb sticks
8800gt 512mb
Samsung F1 1tb
Belkin wifi card (broadcom chipset)
Tagan 480W PSU

This machine has been running fine until a few days ago, now whenever I turn the machine on, it takes a few attempts to start up, and when it does, the CMOS settings have gone back to stock. I have to reload the settings from a profile to get my overclock back. Also, everytime I reboot it takes a few tries to start up, and when it does boot the clock and CMOS settings are back to normal.

I've changed the motherboard battery, so it's not that. I'm about to flash the latest BIOS on there but I doubt that will do much. Does anyone know how I can fix this as it's driving me crazy!

Clear the BIOS and start again?

Sounds like the overclock is failing repeatedly and the BIOS goes back to defaults as a failsafe to me. Try backing off the overclock a bit.

Do you mean flash the BIOS to latest version or clear the CMOS (or both!) as my computer will not work with a blank BIOS.

The overclock is fine, passes over an hour of Intel burn test, temps below 70 also. I guess it could be the PSU playing up, I'm tempted to try another PSU if a BIOS flash does not cut the mustard.

If reflashing the BIOS doesnt work I'd still put it to stock just to see.

Absolutely sure you replaced the battery the correct way up?

Tagan isn't any highest quality brand so could be PSU.
But could be also something in motherboard.

So first thing to do would be trying with different PSU

Certainly not a no name brand though :confused:

Quite possible could be the PSU causing an issue though, you proven the OC is stable but have you tried booting at stock to see if the same issue appears?

Would also clear the CMOS and try it then, failing that update the BIOS (but i find it unlikely to be this)

Ok, I've gone to the newest BIOS (F14) and reset the CMOS and put in all my settings again.

The battery is in the correct way up, and at least now it seems to be remembering the time. It still loses the overclocking settings when I reboot tho, which is wierd, it takes 2 attempts to boot.

When running at stock then I get no such problems. When I get time I'll try a 600W Seasonic PSU, I know Tagan aren't amazing but they're better than Hyper!
