Periodically the bios settings will change causing my computer not to boot into windows. I have to reset the settings to get it to boot correctly. I think it may be my psu (700W) and my mobo calls for a minimum of 750W for the setup I'm running. Could that be the problem? If needed my specs are:
Mobo: EVGA 680i
GPU: nvidia geforce 8800gts
Cpu: core 2 duo e6700
PSU: 700W http://tinyurl.com/glnun

Your basic input output system (bios) usually has two types of memory; volatile and nonvolatile.
Your default settings are set by the nonvolatile memory and, thankfully, can't be screwed with (normally). The volatile memory is usually what people think of when they deal with the bios and it requires a voltage to sustain the settings.
The most common reason for you main board to loose its custom settings would be the small 3 volt battery that is inserted in the main board. These batteries will last anywhere from 6 months to many years depending upon how often your computer is turned on. When your computer is turned on this small 3V battery (usually a 2032) does not supply voltage to the volatile memory, only when the PC is off. So the more your computer is off the more often you will need to replace this battery.
I would change this battery before going into anything more detailed. Wow, 750 watt power supply. That's an awfully big supply, you must have a lot of power hungry peripherals. I don't believe that this would cause your bios to reset.
Good luck.

I'm having the same issue. Periodically my bios settings will change (not all back to default, just some) when I boot my computer. I've flashed the bios to the latest version. It starts wanting to find a PS/2 mouse and doing a full post (counting all the memory) and not the quick one. I'm forced to reset my settings back to default, then manually reconfigure them. A real pain and I'm thinking I'm going to have to send it back to EVGA. :(

Yeah, sounds like CMOS/BIOS arent synching up, any number of settings there, but is usually a battery or your setup is toasting the battery. Stepping 8? any faster and that could confuse the I/O sectors. I/O sectors would start looking for a solution and toast the battery in the doing.
700w is pretty heavy duty, have you tested the actuall output of the PS?

I would check to see if there is a bios update for your motherboard. Also your cmos battery maybe going dead.
I would check for those two things the bios battery is pretty cheap about $4 at most.

Sounds like your CMOS battery has a problem. If the CIOS setting keep getting wiped out everytime that you turn off the computer then that's it for sure. Then the battery is dead for certain.

replace the battery on your motherboard. Little round silver thing in the far corner by the power on self test LEDs.

Likely it's the battery on the motherboard. Needs to be replaced.

Yes try to get a bigger power supply if you can as the power draw might be too great and causing everything to reset.

Install a new battery.
