So, I just built a new box and had pieces that was going to make up for one of my brother in-laws to use.
So, bought a case and put the pieces together and turned it on..fired up...unplugged it, put the casing on...now, won't turn on.....

So, I took the whole damn thing apart again, with ONLY the cpu/fan attached..plugged in the PSU (with power header as well)...nothing..

Changed the power header to an old HP I had sitting near..nothing
Plug the PSU into another computer, works
plug another power supply into my new build..nothing, does not work...

So, I don't think it's the power supply..but, I have everything stripped down except for the board..nothing. The green light shows when having the PSU plugged in, so the board seems to get power..it just won't do anything....

My board is the INTEL 975XBX2KR


Any suggestions....?

When it fired up at the start was it in the case or out?
So when you say,"...unplugged it, put the casing on...now, won't turn on....." I assume that it's in the case.
Have you pulled the board out again and tried it?

To answer both questions.
I believe the MoBo has a built in speaker


2nd response,
Yes, I had everything in and booted..fans spun;everything working. But on the sides of the case, pushed the button..nothing. So, took everything out and now have the Mobo sitting by itself w/ only the PSU plugged into it. Still nothing. Click the PC power button and nothing fires...not a thing. Like I said, change the power head to a few different ones and same thing...nothing. . . . .

I built a new machine and the only thing I took w/ to the new one was the PSU. So, in reality, the only thing I had to replace on my old machine was a PSU. Bought a new one, same model that was there before(corsiar). I didn't like the case so replaced that as well.
This build worked fine a month or so ago. Not sure the issue now. Like I said, the only thing that is diff is the PSU, but I put that into another old machine I have laying around and it booted fine...

PSU brand and model number, watts?
Ram brand and serial number, volume, speed?

INTEL 975XBX2KR
http://www.intel.com/p/en_US/support/highlights/dsktpbo...

Q6600 is supported -
http://processormatch.intel.com/COMPDB/SearchResult.asp...

Ram -
http://www.intel.com/support/motherboards/desktop/d975x...
System memory features. The board has four DIMM sockets and supports the following memory features:

1.8V and 1.9 V DDR2 SDRAM DIMMs
Unbuffered, single-sided, or double-sided DIMMs with the following restriction: Double-sided DIMMs with x16 organization are not supported.
8 GB maximum total system memory
Minimum total system memory: 128 MB
ECC DIMMs and Non-ECC DIMMs
Serial Presence Detect
DDR2 800, DDR2 667, and DDR2 533 MHz SDRAM DIMMs
"Remove the Primary PCI Express* x16 (electrical x16 or x8) video card before installing or upgrading memory to avoid interference with the memory retention mechanism."

The motherboard only supports Windows Vista, XP, and Windows 2000
http://www.intel.com/support/motherboards/desktop/sb/CS...
"Intel does not currently plan to develop and offer Windows 7 drivers for any of the discontinued desktop boards "


The PSU, is it AT ot ATX? The motherboard with 20 pin connections require AT PSU whereas 24 pin connection requires ATX. The difference is that the 3.3v and 5v rails provide higher watts than what is provided in ATX PSU however, the 12v rail in AT PSU is somewhat lower that in a simlar type proffered by the ATX PSU model.

Ten,
I can get you that info..but would have to grab it...but the thing is, I don't think it mattes.I do not have any of the components connected. The MoBo simply will not boot. Can't get the PSU to kick in, the CPU Fan to run..anything.

Like I said, this is the same build I used for 6 years (swapping PSU). Should still work. Used the same make and model of the PSU as I did before (Corsair Builder 500W 80 PLUS Bronze Certified ATX12V Power Supply)

You have to have ram installed.

The PSU is most likely at fault however as this motherboard is slightly out of date (you can't install Windows 7, Intel have no drivers for it), it just might be that the motherboard is actually faulty due to some sort of issue. They do eventually cark it.

DIMM Type Processor system bus frequency/Resulting memory frequency
DDR2 533 800 MHz/533 MHz
DDR2 533 1066 MHz/533 MHz
DDR2 667 800 MHz/667 MHz
DDR2 667 1066 MHz/667 MHz
DDR2 800 800 MHz/800 MHz
DDR2 800 1066 MHz/800 MHz

Basically, for your ram to be properly 1:1 with the cpu, it would need to be DDR2 800 (800mhz).

I had to add that info, the Intel site for your motherboard is slowly being eaten up by the Intel webmasters and am having problems accessing parts of the spec pages, as per links in previous post.

So this board that is not firing up is the 6 year old board from your old build.. right?
If so I would hazard a guess that it has expired.
Now the question would be, what if any board to replace that dead one that supports the 775 socket.
You could knock on a few local shop doors to see if they have any working 775 boards they'd like to get rid of or look on your local Kijiji/Craigslist to see if you can score one there.
If you can't find one cheap then I would suggest a cheap combo from Newegg.
