please help diagnose my Abit IS7-E

Recently I purchased an OEM Abit IS7-E motherboard and I think it may be busted. It won't post. Here's what I tried so far to eliminate other possibilities:

tried 2 working CPUs (tested in another P4 machine so I know it's not the proc) - one is a p4 2.4c 800fsb, another is a celeron 2.4 400fsb

tried 2 different video cards (tested in other systems so I know they work) - one is AGP Radeon 7200, one is PCI S3 Trio 4mb

tried 2 different 350watt PSUs (tested in other systems so I know they work) - a Zalman 350watt and another generic 350watt

I know the RAM works because I just pulled out a stick from my main system and used that.

I thought maybe something wasn't grounded so I installed the motherboard in a case (before it was just sitting on my desk). No go.

So, here's what happens. Everything is plugged in and the motherboard receives power (it's not running, but it has power so one of the LEDs near the connection headers is lit green). When I hit the power switch, another LED below that one turns on and is lit red. Both the north bridge and CPU fans spin up. The system doesn't beep (it did when I didn't have any ram in there ... so I think the board may kind of work).

So why doesn't it post (i.e. nothing shows up on the screen)??? Maybe there's some jumper I'm unaware of? Looked but couldn't find any suspicious ones. I also reset the CMOS a few times (and even took out/replaced the BIOS battery). No dice.

By the way, here's a picture of the two lights I mentioned earlier. It would really suck if this board is dead.
 
in your thread you said

"No beeps on startup. I forgot that the RAM is PC3200 which I am reading may contribute. I will take out the Mobo & try booting as suggested below after I read the info. Thanks."

the ram I'm using is pc3200 kingston. how does that contribute? should I use some other type of ram? do I have to have 2 sticks?
 
A red LED below the AGP slot? Indicates the card's faulty, not a 1.5-volt or 0.8-volt card, or is not seated completely in both layers of contacts in the slot (only halfway down). If I recall correctly. 😉 I'll pull up the manual and check.
 
no, it's a red led below the green led that comes on when the motherboard gets power. both are located near the lower right corner of the board (next to the power/reset/hdd led/power led/etc connectors).
 
Ooops, I've been reading too many Asus manuals 😀 Sorry, I see that one of them indicates board has power, the other indicates the board is fired up. You do have 😱 the ATX12V cable plugged in, right? 😱 Keyboard's in the purple port, mouse in the green port (for PS/2 types)?

More no-run/no-POST things to check here (first link on the page).

BTW if you plan to use SATA on it once you get it running, then let me just get this in right away: ---> :camera: They can be a rough ride to get them to run Windows Setup and then to boot from SATA.
 
yes, that cable is plugged in. it shouldn't matter if the keyboard or mouse are plugged in/not plugged in ... it should still post regardless. which it doesn't.
 
I'm saying, if they're plugged into the wrong ports. I've seen the keyboard-in-mouse-hole cause your symptoms with my own eyes, so check that... easy to check, anyway.
 
everything is plugged in correctly. I'm going to RMA the board. douche bags didn't even sell me a new board, I can tell it was used (dust collected in-between the fins of the northbridge cooler).
 
Disconnected all front-panel connectors except the power switch? Reset the BIOS to default (Clear-CMOS jumper)?
Is the Clear-CMOS jumper set to clear, which will stop a board POSTing or even powering on?
