New PC wont start... HELP!

[brentonhill]

OK so I have got all of my computer parts but somthing is not right.

I have:
HX520W PSU
Asus 650i
e6600
2gb mem
8600gt
sata dvd
sata hd
1 front and 2 rear case fans.

when i turn on the psu the motherboard light turns on and when i hit the on button on my case the psu spins for a second and then stops.

Help me please!
What could I have done wrong, this is killing me!

Have you plugged in the four pin plug as well as the 24 pin into the motherboard?

[Recoil]

as spiral said - check that the connectors are sitting flush with the board - and that you have attached all that is needed to power the pc..

Strip out everything which isnt needed HDD's/DVD's just leave 1 stick of RAM in and fire it up then - see if its becomes stable in BIOS - then slowly add the parts in "bit by bit"

It may just be the case that you have missed something by accident - or something maybe causing a short..

Take your time - go and chill for half an hour then come back to it - with a fresh attitude to it (always helps with me when I cant figure something out)

[Clunk]

Did this myself yesterday, forgot to put the 4/8 pin plug in and it did exactly like yours.

[Madafwo]

If none of that works strip everything out of the case and start with just the CPU/HSF. Power it on and if the same happens you probably have a duff motherboard. I doubt it would be the PSU or the CPU.

If it changes and the system is powering up add the components one by one.

You will probably find it is one of the power connectors you have missed though.

Could be a short. Putting the mobo on cardboard outside the box would check that.

[brentonhill]

I didnt miss any power. Was up untill 3 last night trying to figure it out and then got up in the morning and had a play but can not go back to it untill monday now.

What does it take for the mobo to die cause I suspect it was that . Had all the power in.

When I go home I am going to try it with just 1 stick of ram, the pro and the mo and see. grrr

sounds like the mobo shorting - cured by them red washers. if none handy then i just use sellotape over every mounting point. usually cures problems.

[Thorsson]

Could also be a duff PSU. Seen similar behaviour before from one.

Are the MOBO case risers correct?

make sure nothing is touching the back of the mobo, ie only use the ones you will screw in

[Biscuit]

you could try flashing the bios

[mrbenns]

may well be a faulty stick of RAM, have fixed 2 pcs in the past week with exactly the same symptoms, and that was what was wrong with both

I am unsure, what should they look like?

If my mobo is raised then the back panel will not align correctly. hmmm

[Supershanks]

As Thorsson said earlier take it out the case & have the minimum components connected. If this is a shorting issue then your board should start.

But, u don't need washers, or sellotape the mobo risers are meant to earth with the mobo, provided they are only located against the mounting holes in the mobo. with the mobo out check that the standoffs are in the right position to match the mounting holes.

What memory have you, some have issues with memory volta needed to operate memory being higher than the default. most performane ram works on over 2v whilst default volts are around 1.8~19v if u can try some cheap crapo memory., that might fire up, enabling u to get into bios increasing the vdimm to 2.1v say then shutting down , turning off & putting your main memory in.

luck

[brentonhill]

I did not put it on the raisers because it doesnt look like the back plate will align if I did. I am home on tuesday so I will give it ago then because I'm prettys sure that will fix it!! Grrrrr fingers crossed!

[kalniel]

Yeah they need to go on risers - though getting the back plate lined up can often be a real pain, it's meant to go that way Good luck!
