IS7 ghost random reboots. Help please!

[Darland]

Hello people!
I'm writing from Brazil, so sorry for the bad english.

I have this configuration:

Abit: IS7 (BIOS updated to 22)
Intel: P4 3.0 GHZ, 800MHz FSB
Kingston: KVR400x64C34/256 x2 Slots 1 and 3(Dual Channel)
Matrox: G-450 Dual Head (Video card)
Seagate: Barracuda 80G 7200 Sata HDD x2 (Raid 1=mirror)
Realtek: Lan onboard
Realtek: Audio onboard
Windows 2000 Pro (SP 4)

My problem is totally random and inexplicable reboots.

Some considerations:

1. In the power management on BIOS, "Restore on AC power loss" is set to power off, so I think that we can forget power supply failure, am I right?
Let me explain further, we have an ATX PSU 828C (http://www.sdc.com.br/Conteudo/Produtos/Anexos/ACE-828.pdf) powered by a 24VDC power supply. So I think if we have low voltage or power this BIOS config will make the mobo stay off, right?

2. The option "Automatically Reboots" is unmarked and I don't see a BSOD;

3. Some Bio settings. Ask if you need more details:

Hi, Welcome to the forums.

To give us more idea about your problem,
See if you can do the following:
Control Panel
Administrative Tools
Event Logs

Look in the event logs for 'X' and '!'.
Post back to this forum with the SOURCE, EVENT ID, and any text that goes with the error with the same timestamp as the reboot.

Also, it might be worth disconnect all your drives except your main hard drive to see if it is a power issue
