Gigabyte GA-8IPE1000-G wont POST

[The Terk]

So I acquired a new box through work and it is not able to boot. In the default loaded setup (memory, hdd, agp card, etc) I do not get any POST screen or speaker beeps, so it is time to investigate. All fans, harddrives, and loaded CD-ROM drives spin up and it looks like it's thinking (hdd activity light doesn't show up on case though)

Changing out AGP video cards and using a PCI video card do not provide any graphical output and no BIOS beeps.

Taking out all memory gives me a BIOS beep (very short) but does not output anything to the monitor (using all video card options)

The original CMOS battery measured in at 1.8V (3V rated battery) so I replaced with a battery that measured in at 2.8V - still no go.

Anyone have another idea I could use? Thanks in advance

Components (that I know of):
Gigabyte GA-8IPE1000-G
Intel Pentium 4 - ???Ghz Northwood (Socket 478)
256MB DDR400 (PC3200) - can give model number if needed
80gig SATA150 - Seagate I believe
Antec 380W PSU
PNY AGP 6600GT Video card

I don't know how low you can go, @ 2.8V, I'd consider it dead.
A new 3V battery is well above 3V
I'd eliminate that first.

Hmmm....a bad battery would not cause post failure. It just wouldn't retain settings when the system is powered off, I believe. My first impression is that you got a gimp motherboard which does happen. I've bought more than one MoBo brand new to discover that it wouldn't execute POST. So...here are some things I would try, if you have some extra parts or a friends computer to do it with.

1. Test your CPU and ram. If either has gone bad, it could cause a POST failure.
2. Check that your CPU is installed properly, has adiquate cooling paste on it, and is secured under a functioning CPU fan.
3. Check the motherboard using other components than the ones you are using right now. Try a different CPU, different RAM, or a different power supply, one at a time.
4. If none of the above provide answers for you, I'd return the MoBo and get a replacement.

Hope this helps. Good luck to you.
