I just built my first pc and on bootup I'm getting this message:
CMOS settings wrong
CMOS date/time not set
Chassis intruded
Fatal error...system halted

I tried to clear the CMOS, however I don't know if I did it right. I cleared the RTC RAM (CLRTC) because manual says the jumper allows me to clear the RTC RAM in CMOS. I moved jumper cap pins from 1-2 (default) to pins 2-3 and kept it that way for 10 seconds...then moved it back to pins 1-2. On bootup I'm holding down the delete key to enter BIOS, but it doesn't get that far as I'm getting the same errors as above.

What does this may mean? Also I'm getting three beeps on bootup. I checked my memory and it seems to be seated properly.
I have the P4C800

Any suggestions?
 
Easy solution: Unplug everything from AC, hit the power button to discharge everything, pop out the cmos battery. come back tomorrow.
 
"Unplug everything from AC, hit the power button to discharge everything, pop out the cmos battery."

What's the AC?
 
AC being the wall power sockets.

AC is what runs in your home, aka Alternating Current.

DC is what your power supply converts the AC to for use inside your computer.
 
My mind was set on inside computer problem. I never thought I could help fix this problem outside of the computer. Of course AC is the house current. Ok. I'll give it a try. Thanks
 
The CMOS battery is inside the computer, make sure you take that out....
 
Dew gave you the quick method of clearing CMOS. The long method is to pull the battery and wait a while... I've had CMOS not clear for 24hours in the past, that's when I started as Dew said.

Unplug the system, remove the CMOS battery, then press the power button. Generally the fans will start to spin, then the system powers off.
Its best to hold the power button for a few seconds, make sure its dead.
Put your battery back in, plug it up and see if clearing the CMOS fixed the problem.
 
As you know it's difficult to get at this battery and to see what is holding it in place. I've done a google search to get a clear picture of where and how to unclip it, but I've had no luck. The manual itself is useless in this case. Also what parts of this battery can I safely touch without shocking it out?
 
I got it. Thank you all for your suggestions. Being my first build, sometimes I'm so nervous that I can't think clearly but I keep on plugging.
 
It is normal for a new board to report a CMOS error on startup. it should load the default settings and be fine after that.

and if you do need to reset the CMOS you only need to remove the battery for a few mins.
