BIOS reset when wake up from sleep


I'm using Windows 7, and when I try wake up my computer by pressing a key from the keyboard or pressing the power button from sleep (either selected from start menu Sleep, or automatically entered by the power saving options), it doesn't wake up.

The only way to get my computer working again, is by pressing the reset button, but after the reset, the bios is also reset (it prompts me to Load Default Values or Enter setup).

Note: I've updated the bios to version 1004, and the problem still persists.

My computer configuration is the following:

CPU: Intel Core2Quad Q6600
CPU Cooler: Arctic Cooling Freezer 7 Pro Rev.2
Memory: 4 X 1 GB Kingston DDR2 800mhz
Motherboard: Asus P5QL Pro (Intel P43 Chipset)
Hard Disk: 500 GB Samsung Sata I
Power Supply: LC Power Arkangel 850W
Graphics Card: PowerColor ATI Radeon HD 5770 PCS + 1 GB
Operating System: Dual Boot between Windows 7 Home Premium and Ubuntu 11.04, both are 64 bit.

Thanks for your attention,

Maybe CMOS Batt is empty. If shutdown normally when computer starts BIOS settings is remain or reset to defaults?
Hi looks like you have put together this computer, first thing I suggest is that check all the connections from the front panel to the motherboard.
Also please confirm if the BIOS resets if you shut down the windows and start the PC again?

If I shutdown the computer normally and turn it on again the bios won't reset, only after sleep.
OK, I will check the cables and battery, thanks for your suggestions, soon I will reply with the results.

Check in the BIOS or on the PC. their is a option that says something along the lines of "wake pc up after it is asleep". make sure that the check box is ticked. allowing the PC to be started using any key or the mouse.

Hi again,

I've checked the cables and measured the battery with a voltimeter and it appears to be good.
But now, when it goes to sleep, it shuts down after some time, and the bios settings aren't lost. Windows generated some dump files, which I've attached to this post.

The attached zip, contains a document generated with the command perfom /report and the dump from the blue screen generated with jcgriff (please check the latest one, from today at about 17pm).

Thanks a lot for your attention.
