New Built, no POST

Hey,

My bits came from overclockers today and I assembled them and tried to boot up for the first time but nothing seems to be happening. When I press the power button the fans spin round and everything seems to come alive but there is no signal on the monitor and it stays in standby also I hear no beeps coming from motherboard. I'm pretty sure everything is plugged in correctly and there are no warning lights coming up on motherboard that I can see. Is there something really basic I have missed that might cause this?

Specs:
C2D E6750 (New)
2GB OCZ Platinum 2 XTC PC6400 (New)
Asus P5K Intel P35 (New)
X1900XT 512MB (From Old PC)
X-fi Xtreme Music (From Old PC)
WD 74GB Raptor (From Old PC)
WD 120G SATA (From Old PC)
WD 400GB SATA II (New)
Seagate 80GB IDE ( From Old Old PC)
Philips DVD-RW (From Old PC)
NEC DVD-RW (New)
Acoustic Energy Aego M 2.1 Speakers (New)
Logitech G3 Laser Mouse ( From Old PC but only 2 months old)
Logitech Media Elite Keyboard ( From Old PC but only 2 months old)
LG 22" Widscreen 2ms 3000:1 TFT ( From Old PC but only 1 months old)
XP SP2 ( From Old PC)

Now with my old PC when I went to press the power buttton nothing happened and I assumed the motherboard was dead hence this upgrade but maybe its one of the old components still haunting my new system?

Thanks

Try reseating everything and i take it you didn't just put the Motherboard into the case without putting the pins in which hold it off the case?

Additionally try clearing the CMOS (See your mobo manual) after reseating everything.

Nope I put the risers in, the only thing which I did not manage to do was put the 4th restraint in fully on the CPU cooler because I felt if I pushed any harder the Motherboard would snap!

If the Heatsink is not properly seated, CPU's can hit major temps in seconds from a cold boot.

I assume you seated the cooler while the mobo was out of the case?

I applied the HSF while it was inside the case, perhaps a bad move in hindsight! The HSF is secure to the motherboard though and is not going anywhere but I will rebuilt it now.

try with one stick of ram, i sometimes forget to plug the PCI-E power to the card so make sure thats plugged in.

Make sure the second motherboard power cable is plugged in, this can usually be found near the CPU and can easily be overlooked if you have a large CPU cooler hiding it.

PK!

Which PSU are you using for this new build.....?

MG42Maniac · 24 Aug 2007 at 16:55

Hiper type r 580w.

By 2nd motherboard connector do you mean the 4 ping one? If so this is plugged in.
Also one of the pins that holds in the HSF is well alittle different from the rest of them and as such will not push fully down ( top right one):

Because of this there is not full coverage of the chip.

That pin looks like it needs to be pulled out a bit or twisted up.

Does the mobo have a d-bracket?

Edit: If it does, are they all green?

MG42Maniac · 24 Aug 2007 at 17:53

It has one gren LED lit to show power is on and LED's are supposed to lit if a PCI or PCI-E card is incorrectly fitted and none of them are lit.

I have completely rebuit the PC and am now using the bare essentials and it still won't POST

Possible hardware failure?

Edit: Just tryed booting up it up with no VGA at all and it did not beep at all so that surely cannot be good?

MG42Maniac · 24 Aug 2007 at 19:24

I think I fixed the problem, It only likes one of the sticks of RAM. If I try and use the other it refuses to boot!

Thanks for the help guys, people like you make this forum one of the best there is!
