I recently had three systems lockup(weeks apart from each other), once rebooted harddrive light remained on but no activity, and the cmos did not boot. The first system did this and i tried everthing from memory switch to cmos battery, nothing, power would come on but motherboard would not initialize. This happend on three systems, one harddrive corrupt, one hardrive loss partitions, third zero errors(this is after i replaced HD's in new system. The first system is now running again(dont know why)they are all same motherboards GMB-P57IPS-V0, i replaced cmos battery but cant get the other two to boot into cmos. virus?

Have you tried latest cmos upgrade for the motherboards you are using.

Possible boot sector virus also. Try running latest virus checkers and clear cmos memory before that.

Check manufacturer web site if other people experience similar problem

good luck

Since they are the same systems, I assume they all have the same power supply? If your power supply is not supplying correct voltage the computer will start to boot (HDD light) but motherboard will not initialize. Try a known good power supply, orcheck your voltages with a DVM.

My first instinct would be that you have had some type of power interruption and/or surge. Such as that created by a nearby lightning strike. These types of surges typically cause latent defects which don't always surface immediately. If you wereplugged into on of the $10 power strips w/surge protection, it means nothing. They are useless. I wouldn't spend less than $40 on a surge protector. If you pull all add-on cards (minus the video card) and disconnect HD cables and it still won't POST, it's either the CPU or the motherboard. If you can swap out the CPU and it still won't POST, it's the motherboard.
