Anyone come across this problem?

I've tried changing to a new CMOS battery and hasn't resolved the problem.

Spec below:

CPU: Q6600
Motherboard: Gigabyte P35C-DS3R
Ram: 2GB Corsair PC 6400
GPU: MSI 5850
PSU: Corsair 620W

At the moment its clocked to 2.7GHz. I know when I switch this PC off tonight and back on tomorrow its going to go back to stock.

Any ideas what I can try and do?
 
Sounds like your bios chip is gorfed. If you are sure the button cell is a goon un, search ebay for a replacement bios chip. You can normally find them on there for about £7. Then flash it again with the latest firmware and you should be good to go. Take care getting them out and make sure you put it back the right way.. they DO go in 180 degrees out on some boards!

the P35-DS3R doesn't have a removable BIOS EEPROM chip.

OP, try replacing your BIOS backup battery.
 
The mobo can't be dead! is it my overclocking settings?

For example the CPU is clocked at 2.7GHz and when I run Prime95 it worked for hours without problems. Then when I shut down and reboot its lost its settings. Is it something to do with the overclocked settings?
 
Are you loosing the time as well? If your computer is not keeping time when switched off you have a problem with the backup battery, if it is keeping time, that eliminates that problem.

If you replaced the battery and it is still not keeping time, check the "handbag jumper" for resetting CMOS. You could get the symptoms you are seeing if the link is missing altogether rather than in the wrong position (which would prevent the computer booting). In the "normal" position the link connects the battery to the chip, in the reset position it shorts the chip power to ground resetting it. So if the link is missing altogether
the chip gets power from the PSU when switched on, but not from the battery when switched off.
 
Interesting thread this as I have a very similar problem.

I have a 8400 Quadcore running on the same P35 motherboard Rev1.00
4 gigs of GSkill DDR3 ram.

Managed to overclock the chip and memory successfully to enable a 3.2ghz overclock.
Ran a memtest for a few hours in windows 32bit sp3
and that seemed very stable. Played a few intensive games
all well and good.

Powering on the PC in the morning and blue screens
and hangs in windows loading procedure.
Had to reset everything in the bios to stock in order
to achieve full windows load up and stability once again.

I'm going to try a new cmos battery because
I did get a wrong clock time on one startup.
Nevertheless maybe the p35 board just can't cut it.

the P35-DS3R is a well designed board - i've had my Q6600 at 3.6GHz in it and it handled it just fine.

i suspect that something other than the board design is at fault, it is definitely possible that the board is faulty.
 
You are probably correct there about the motherboard.
But I'm trying all kinds of things to find out what the problem is.

I haven't got anywhere yet.

Even setting everything to stock does not make any difference.
I'm getting regular bluescreens. Although I think that if I immediately go
into the bios on bootup and leave it there for 5 minutes then save and startup,
it might work and start up OK.

But I don't know what that says about the system.
 
Is it just the overclocking settings that clear? How about boot order? Try enabling/disabling some other features of the mobo and see if they return to default on boot.

Identifying whether its just the overclocked settings or the whole CMOS that is clearing mat help in identifying the problem.

If it is everything going back to default it could be that you have the CMOS clear header on the incorrect pins.

If its just the overclocked settings then I would suggest that they are causing some sort of stability issues (prime is not the be all and end all of stability!) which is causing the mobo to return the clockspeeds to a stock state.
