AMD 64 overheats when booted into BIOS

This is just not my week for overheating issues...First my Dell laptop...then my Subaru Outback...now my AMD desktop...

I have an AMD 64 X2 4800+ CPU on an ASUS A8N SLI32 Deluxe mobo. When I boot up the computer into Windows XP 64 it consistently runs at around 40 degrees celsius.
When I boot the computer and enter the BIOS, and go to the temperature monitor, I watch the temperature rise up to 70degrees celsius and then the computer auto-shuts down. Obviously since it runs fine when in the OS, it is not a life or death matter, but I can't go into BIOS and stay there very long and I'm trying to configure the RAID settings.

Any ideas?

Thanks, Kevin.

Fans all are running ok. BIOS shows rpm's for CPU Fan, Power Supply fan, and Chassis fan.

One thing I noticed with the AMD CPU is that it came with a fan/heatsink and there was already a layer of thermal compound applied to the heatsink. I am wondering if I should add more thermal compound?

Also, I am trying to update the BIOS to make sure I am on the latest version.

I will give an update once I get the BIOS updated.

Thanks.

Ok, I have bigger problems now. I flashed the BIOS and now I do not get any video.
It actually sounds like the machine is booting up though. I read that sometimes when you flash the bios, it disables PCIe video so you have to reenable it...Through the BIOS !
so you have to put an older video card in it to boot up and reenable PCIe
I'm going to try putting a normal PCI video card in there and see what happens.

Stay tuned...

Did you 'clear the CMOS' with the system unplugged from the wall?
I have seen several mobos suggest this as a way to avoid some possible update problems.

I was finally able to get back the video (I did not need to use a different video card). I just had to RTFM on how to properly reset the CMOS.

Steps -

turn off computer
unplug power from wall
remove all peripherals including ram
remove cmos battery
move cmos jumper from 1-2 to 2-3
wait 5-10 seconds
move cmos jumper from 2-3 to 1-2
reinstall cmos battery
reinstall peripherals (as few as possible just to get things up and running)
power on machine
reset BIOS to defaults.

Now I'm back to trying to determine if I still have an overheating problem.
I'm giving up on XP64 and going back to XP32.
Also trying to get RAID configured, but that's for another day and perhaps another post on EE...

Thanks for all your ideas. I will split points as best I can.

Thank you much. : )

>> how to properly reset the CMOS
First time I have heard of taking the peripherals out. But it makes sense.

Good luck on the temps.
