What causes system bios to reset by themselves? In this case it's a K7VZA Motherboard with an Athlon 1000 processor runing Win98SE. The PCI IRQ assignments were set manually to avoid network/graphic card/sound card conflicts. Suddenly last week the machine started freezing after 2 minutes of inaction at the keyboard. On reboot I saw that the bios setting had gone back to default so there were device conflicts like mad. I corrected them and the computer booted fine but still froze after 2-5 minutes of inaction.

What gives??? Any ideas???

Thanks,
Sara Hedgpeth

What causes system bios to reset by themselves?

This could be caused by a bad motherboard battery.

The battery power is enough to allow CMOS settings to be "remembered", and a bad battery could be the cause for the CMOS to "forget".

Did you at any point allow the computer to set it's own IRQ's? Was there a problem that caused you to do this manually. Allow the computer to set it's own IRQ's and then this way you can at least see where the conflicts are--if any--and then troubleshoot from there rather then manually setting all IRQ's and then not knowing for sure what the problem is. The BIOS should reset only if you do it manually or perhaps do to a faulty battery, however, you never know with a Windows operating system how it will react to certain things. First make sure that your IRQ settings are not causing the problem by doing what I mentioned above. Then check battery and motherboard. I would also recommend contacting the motherboard manufacterer if problem persists.
