Intel D845GLVA Motherboard problem

[carbuff]

Hi, Im having a bit of a problem with this motherboard. Ive got the bare board on the table with a 2g celeron, 512 mb of ram and the power supply hooked up. The cpu fan is plugged in to the cpu fan header. When I short the 6 and 8 pins on the header the psu should start up and the cpu fan should spin regardless of if it posts. Im not even up to that yet. I always test stuff outside the case before installing it to make sure it isnt doa. Well, i get nothing. No psu starting up or anything. the little green light on the board is lit but thats it. I even dragged an old nforce2 amd board out of the closet to make sure I wasnt losing my mind. Even with no cpu or memory that board was able to start the psu and make the cpu fan spin. Is there something special about intel boards that Im not aware of? Normally I would just say the board is doa but its the 2nd one from the same seller with the same problem so I started to think that maybe I was doing something wrong. I just want to make sure before I contact the seller again. I dont think he tests these at all but he warranties them. Other buyers have left him good feedback already for the same auction so Im a bit confused. any ideas? Thanks. Oh, Ive cleared the cmos already.

6 and 8 pins on what header? try just shorting the power switch pins

The board definitely supports the CPU?

And the CPU is working?

Hi, yes those are the power switch pins on the front panel header on the motherboard. According to the manual and the bad motherboard still in the machine, (the one Im going to replace), those are the power pins. I get nothing when I short them, no fans, no power supply, no nothing.

Hi, the board definately supports the cpu as the whole combo was supposedly a working pull from another machine. Im assuming that its working. But as I stated in the other post it shouldnt matter as it should at least start the psu regardless of having any cpu or ram at all, unless intel brand boards have some special needs that Im unaware of. Normally, Id just say ok, its doa, but I find it hard to believe that the guy would send me 2 doa mobo-cpu combos in a row.

Silly question, but is there a 4 pin connector on the board next to the cpu? If so, do you have it plugged in?

Do you have the motherboard manual? If not, then you should find on the Intel website. I honestly haven't looked at the board layout to see if you have a plug like that near the cpu. Also, is anything touching the backside of the board that could cause a short? Okay, this one is reaching a bit. My experience with shorts is that usually things will try to fire up at first.

Okay, I lied, here is the link to the manual: ftp://download.intel.com/support/mother ... nglish.pdf

4-pin board connector is on page 9, item D. Is that plugged in?

Looking at the pin layout for the front panel on pages 60 & 61. I'm wondering about pin #9...

Gosh, this has to be one of the worst posts I've written, but I'm not going back! Check out the connector that I suggested from page 9. I think what you are describing sounds like it could be that.

Hi, thanks for the help. Yes the 4 pin p4 connector is connected to the psu plug. I kind of wondered about that pin 9 too but according to the info stenciled onto the mobo and the connectors on the old (dead) motherboard in the computer, it is not used. I think this guy is just selling junk that he got in bulk and has not tested. It was cheap but I guess you get what you pay for. Oh, well, thanks.
