New PC won't Start Up

Hi Guy,
I need some help please.I've but the pc together and it won't start.
I've purchased the following items

-GIGABYTE GA-8I915PL-G S775, 915PL, ATX, FSB800, PCIEx16, DUALDDR400
-1 GIG PQI TURBO RAM (2x512) DDR 400 (C2.5)
-Antec Sonata II Case
-Intel pentium 4 3.2 775 (800) 2MB Cache
-Dual DVI 6600 GT PCI- E
-200 GB Hard Drive
-And other items.


I belive i've connected everything right but the pc won't start.I don't see any lights coming on the motherboard.Seems it's a power issue.I had another GIGABYTE GA-8I915PL-G and still same issue.Can you please advise what i should do?

Many Thanks

Simon

 

Did you place the motherboard standoffs in the correct locations and use any fiber washers if included? The motherboard may be shorting out against the case.

 

Thanks for the reply.

I've placed the standoffs correcy
I connected the 24 Pin power to the mb and also connected the other one for the cpu.

Peter how come two power supply?I got the one that comes with the case and i connected it.I had purchase similar cpu last week and did not have any problems.

Please advise

Thanks

 

Unless it is one full block of 24 connectors, the power supply connectors to the motherboard will be one block of 20 connectors and one block of 4 connectors, that is the two power supplies that PeteC is referring to.

No lights, do any fans start?

The CPU may be too "modern" for the motherboard. I found this lately trying to install a Sempron 64 bit, 754 pin CPU on a motherboard whose BIOS did not recognise the 64 bit CPU, it only recognised Athlon 64 bit or Sempron 32 bit, if this sounds familiar you will need one of those CPUs to start the machine, then upgrade the BIOS to "see" the Sempron 64 bit processor.
or
send it back to the motherboard supplier for them to upgrade the BIOS.
Edit: reread and see you have an Intel system, although "the song remains the same ".

Hi Matt,
It comes with block of 20 and you can attach the other 4 blocks,which i have done that.It makes it a total of 24 connectors connecting to the main board.

anything else u can suggest.

Thanks

 

Do you see any "activity" when you press the power button? This is important.

It may not recognise the CPU.

There may be a problem with the type of RAM, although you would probably find there would be "beep" signals.

You may need to let us know more about what "symptoms" it shows.

Run through the "stickies" at this website:

Matt,

Does still Bee even if there is no power coming to the mb?
Ill go through the url and see what ill do.Ill try using different psu

 

I've tested different psu and it worked stright away
seems a faulty psu.Ill return the case.Thanks for the help

 

the last time this happened to me the connector from the power switch on the front of the case was not plugged into the correct pins on the motherboard,
Trev.

 

I'm 100% i checked and still didn't work.
I used different psu and it worked fine.
I wanted to know if the motherboard is faulty,does the cpu startup?


Thanks

 

i replaced the psu and it started normal
however it won't display the monitor due to no singal.I tried different monitor and same issue.

i Installed XFX GeForce 6600 GT 128MB DDR3 into the PCI Express (Black expansion)i removed it again and made sure its installed properly.I hope not a faulty video card.Any suggestion Please

 

How can i Peter?
They screen is not been displayed Just get no singal on the monitor.


Thanks

Simon

 

The monitor is not getting a signal from the graphics card. I just saw PeteC's response and was going to suggest connecting the graphics card's other "head" as well.

Pull out and reseat the graphics card, you can also try cleaning the connectors with a soft pencil eraser.

Does everything else work? Do you see the drive LEDs flash? No beeps?

Since you have had problems with the PSU, I would consider using the "reset CMOS" jumper and after that, maybe removing all hardware and connections and starting again from scratch.

My Gigabyte motherboard has real problems with graphics, of 4 graphics cards I have installed on it, only 2 work, but I must say that it is a 2001 model.
