[Solved] pc home swap build wont boot

[matabhaine]

I had a lot of spares so decided to build a spare pc, i press botton on front of case and it powers on and off when i hold it in, so it isnt that.

 

my specs

1x dvd writer

Intel duo 6600

MSI P6N SLI mobo

2x 1 gig sticks ram 800 ddr2 Vitesta extreme edition A Data

1x sata2 HD 500 meg

850 watt psu almost new, worked fine in other pc with even higher specs

1 palit gf9600gt 1024meg ddr2 128b GC

 

everything worked b4

i have done things like this b4 and it worked fine

 

I am getting no boot up, no beeps, just a black screen, the fans work, hd works, psu fans work, dvd works, have pulled everything out till only the cpu and psu, no beeps, tried all configurations, i may have the front panel headers in wrong but would that stop the machine from booting? thought after reading all i could on trouble shooting, i thought i would ask here first b4 taking it to a specalist to see what might need replaced.

Hi,

 

I suggest that you follow my instructions here: (It looks as if you have done this anyway :) )

I assume that there is a speaker connected on the motherboard ?

 

Try unscrewing the m/board and sitting it on a piece of card / newspaper to insulate it from the case.

Switch on.

You should get POST beeps.

speaker

 

i have a cable from the front panel that says audio, from that there is a large connector with M.B. on the back and several others with mic bios etc, i tried plugging the mb into jaudio jumper on mobo but nothing, i tried it outside the mobo but no beeps with everything out except psu power 24 pin and cpu 4pin nothing, thanx for the link but i had tried all that, one of the fan clips for cpu has snapped the ones that go thru the mobo, but the fan still seems tight, i might change it

speaker

 

i found a speaker small round black plastic with speaker written on the plau plug plugged into front panel jumper but still no sound, lifted cpu, thermal paste flat and spread evenly, re did, no beeps

Beginning to look like a duff motherboard, have you tried it with the motherboard out of the case as Ken suggested? That will at least prove if something in the case is shorting a connection.

motherboard out

 

tried it with the mobo out, maybe take it for a diagnostic at the local pc store and just buy the wonky part i think, but thanx for any replies

mobo touching case

 

the case has built in spacers, i applied the ones that came with the case also, when i tighten the screws, the machine wont boot, when i loosen them it starts up, or that seems to be the problem. the guy in the pc shop gave me eight round sticky pieces of rubber to put on the mobo to stop the screws touching but i thought i would ask here b4 going ahead seems a make do and mend to me

taking the rise

 

well i read a little bit about risers. I had seen something on the net which said make sure u have enough risers and not too many, a piece of paper and pencil was used to denote where and how many spacers etc, well I removed the mobo and counted, nine holes on mobo, but 8,9...10 risers, removed a riser and viola booted up, maybe early days but i can at last get my retro gaming pc setup, thanx for all help and i hope this post helps others in the future.

Good to hear you found the problem, for others following, check the risers are both correct in number, and also in the right places. In this instance a wrongly positioned and one too many was shorting the motherboard to the case. It is an easy mistake to make, you aren't the first to make it and possibly not the last matabhaine.

Happy to hear that you managed to sort it out.

 

The riser was obviously shorting out the m/board to the case - which was why I originally suggested sitting it on card.
