Graphics Graphics card help

I built my new system last night a core i7. I think i have the leads in the right place etc. However when i connect my monitor to the powercolor 4870HD graphic card i get nothing on the display. i have connected the card to the pci-e x16 slot, however on the back of the card are 2 other connector sockets. i connected 1 of my PCI-E power cables to the back but nothing happen, do i need to connect 2 PCI-E power leads to the back? or none at all? Also the fan on the graphic card does not spin. where have i gone wrong?

Thanks

 

You need to connect BOTH PCI-E connectors. Won't work at all without.

 

Thanks for the advise MM vR.

I'm going to be building my first rig soon, and this seems like a problem I would run into also, haha.

 

Thanks mm vr i will give that a go and see what happens

 

I have tried as stated above but still no luck the fan is not even spining and no display. i have tried with two PCI-E cables in the back of the card and also one.

I have put my old PCI card which works as its in my old computer but this did not bring anything on the monitor.

Could there be something i have done wrong on the motherboard a wrong place cable?

 

Try clearing the BIOS.

 

Just cleared the BIO's, by shorting the 2 pins, still the graphic card not working suppose a faulty graphic card.

 

You probably have something plugged in where you're not supposed to, I remember I plugged something in a socket called AC 97 and my system would boot at all.

 

tried removing the ac97 but no luck the motherboard seems ok, all the leds light up on the motherboard ok.

 

Did you plug in the 8-pin motherboard connector? It's usually located in the left upper corner of the mobo, near the CPU socket, CPU VRMs and rear IO.

 

Maybe we could diagnose this better if we could see what was going on. Do you think you could post a picture of the inside of your computer as it is?

I will get a pic up soon, im using a Gigabyte EX58-UD3R motherboard and the PSU is a Corsair TX650W the power connector i have used is a ATX 24pin ( the big one), should i be using the smaller one 8 pin?

 

you need to use the both the 24pin and the 8pin power connections, i presume you mean the 8 pin power next to the CPU? if thats not plugged in there is your problem

 

Thanks crompers thats where iv gone wrong, i have not put the 8 pin plug next to the cpu in. i will give that ago.

 

easily done, let us know how you get on

 

so basically i need the 8 pin top left of cpu connected and the 24pin to the right of the ram both connected?

sorry for daft question new to this...

 

yep thats exactly it, make sure you're turned off and unplugged though obviously!

 

I have good news the graphic card is working i connected both the 24 pin and the 8 pin, the fan is now spinning.

thanks for the help, i will probally be back with another issue later

 

glad to hear you sorted it

remember its always better to come online and ask here than brick your nice shiny new hardware so even if you think its a silly question just ask
