Help IT7 mobo won't boot

[SolrFlare24]

Ok, first off I just got this board *back* after RMAing directly to Abit earlier this month because of other issues.

I have everything set up right on the mobo, I go to power on but the system never boots. All my devices power on and the mobo starts the bootup process but then stops at post code 0d...all this before the video intializes as well.

So far I've tried, changing/removing all my PCI devices, swaping out my GF4 with another video card, clearing the CMOS, and removing IDE devices. No success.

Since I just got this board back after an RMA, I question whether this is an issue with the mobo itself. Is it possible the cause here is the RAM or did I just get shipped a broken board?

look lin the manual normally it tells u wat to do i got the it7 max no probs make sure when u clear cmos u actually clear it mine is finicky wit the clear cmos jumper

I checked the manual and no success there, also I did make sure the CMOS got cleared...yeah I know they can be twitchy.

I have some updated information regarding this problem. Thinking it might be ram I tried changing its slot. Now, no matter what slot its in, I get the following post code: A7 and the system beeps on and off. If I recall A7 is trouble with your ram. So considering that this is a mobo that I just got back after RMAing my last one, you guys figure its the RAM? I just ask because I don't have access to another stick of DDR and will have to order a new one.

Hmm do you know anyone that can try it in there computer? Or do you have a nice local computer store that would test it out for you for free of course?

Have you looked in your manual for what the A7 code means for your motherboard? Also I don't know the brand of the IT7 could you tell me?

Also what happens when you boot without the RAM in? Same error code?

yeah a7 is memory, i get that when i oc my memory to high and just have to clear cmos but you migh have bad mem. What kind is it? size? what proc?

I have tried clearing the CMOS and checking out other mem slots. Its an Abit IT7 mobo, 2.26 P4, 512mb of Official(aka true) Samsung DDR333(have confirmed by checkign serial numbers on both chips and board, its the CTL series not DTL). Here are even more details:

I should also note that this is a board I just got back RMA from abit. I originally sent the board to them because my system started blue screening like crazy, would give a BIOS Checksum error: No Keyboard (on some reboots, clearing cmos would fix until next bluescreen), and it locked up while I was in the BIOS. I figured at first it was simply a bum mobo...but now I wonder if it was really a RAM problem.

The bluescreening by the way also happened during a Windows XP reinstall, I seem to remember hearing somewhere that that might be caused by bad RAM. Also I was originally running my RAM at 3:4 2-6-3-3 with a 133fsb. This worked for about a month, then blue screens started happening, so I scaled back to a 266fsb with a 1:1 ratio and the system worked great for a week then it just up and freaked out.

So with all that in mind, and it not working in any slot on a fresh RMAed mobo...is it just plain bad ram?

I am inclined to say its bad RAM. It's either that or your Motherboard again. But I after you already RMAed it once I am going to recommend getting some more RAM. Also that should have a warranty on it if its original samsung.

Did you try the reset (JP3) on the motherboard, and the PS_ON (JP2)? Try pushing either one in with the power on and see what happens. It will either do nothing or start up.

Tried that...its a no go there too
