I get a beeping, going up and down like a police car in London. I assume its a cpu heat warning, but I can't figure out how to stop it. I've tried to disable the CPU warning to no success. Any suggestions would be appreciated.

I got this info from another forum:

Basic Beep Codes for ABIT AWARD BIOS Motherboards
1. No beep at all - this means your motherboard is dead, either due to a defective or underpowered power supply, poorly seated CPU or RAM, or a dead-on-arrival board
2. One beep - board is working fine
3. One long beep then machine shuts down - faulty, improperly installed or missing CPU
4. 1 short(Beep) System booting is normally
5. 2 short(Beep) CMOS setting error
6. 1 long - 1 short(Beep) DRAM ERROR
7. 1 long - 2 short(Beep) Display card or monitor connected error
8. 1 long - 3 short(Beep) Keyboard Error
9. 1 long - 9 short(Beep) ROM Error
10. Long(Beep) continuous DRAM isn't inserted correctly
11. Short(Beep) continuous POWER supply has a problem
12. A two-tone siren, generally caused by overheating or out of specification voltages
13. Four beeps then machine shuts down. This is because this version of the BIOS will shut down your machine if no fan tachometer signal is detected on the fan header. Make sure you attach a fan to the FAN1 or FAN4 header or clear CMOS to reset to default (no checking).

Assuming that it is beep code #12 in th list, check your cpu temps and voltages in the BIOS. If no luck, it might be worthwhile resetting the BIOS to the safe defaults.

If it's overheating now and hasn't done previously then I would open it up and give it a good clean, check all the fans are rotating etc...
