Help with a 7850

[Xerse]

Hi all, i'm new here and needing help!

I just recieved my Gigabyte windforce 7850 OC today, just fit it all into my case, placed the 6pin power cable into the card.

Boot the pc up (connected via HDMI) and nothing.

I had figured maybe it was the new ram (i also recieved 2x 2gb kingston hyperx blu ddr3) so i removed the new RAM, booted again, nothing.

The fans on the card aren't even spinning.

Silly enough, i didn't even check if this card would be okay with my motherboard - stupid move..

Can anyone help?

I'm running a Asus M4A89GTD Pro (not the Usb 3.0 version)
AMD Phenom II x4 955 black edition
2x2gb OCZ Gold DDR3 ram (and obviously the new kingston ram too)
650w power supply.

Have i done a silly and bought a card that isn't compatible with my motherboard?

(excuse to buy a new board!)

I have that same motherboard and purchased a MSI 7850 when they first came out, and could only get the card to work in my 2nd pci-e slot.

RMA'd it and bought a gtx580.

No problems since.

I thought it may have been a dodgy card but seem it may have been my motherboard to blame.

I've got ONE of the fans to spin now on the card, but nothing else to report.

I will have a look see if it will run in the other PCI-e slot, and see if it's the same problem.

I'm not sure if it's a dodgy 6 pin, or the motherboard to blame. Going to try the other 6 pins i have also, just to be safe.

The way i got ONE fan to run is with the "6 pin-2x molex" adapter in the box that came with it.

I'm perplexed!

Switching the card over to the other PCI-e slot makes both of the fans spin. Still no image on screen. Nadda, nothing, zip.

Yep - i'm just simply replacing this with my old OLDDDD 8600GT. Onboard graphics have always been disabled.

I will double check and make sure the bios is set accordingly.

EDIT: No i won't. Now i'm getting nothing even when booting with my old card and old RAM. Time to throw it out of the window!

I can't understand how or why this is happening?

We're all fixed!

My fix?

I took all RAM out, CMOS battery, disconnected all cables, removed GPU. All that was left connected to the motherboard was the CPU.

I placed everything back, still no luck.

I swapped the OCZ Gold RAM from the prime position, to the secondary slots, and placed the kingston hyperx Blu into the prime positions on board.

Booted up fine with my old 8600gt like this.

Replaced graphics card with new card, placed 6pin connector into the card, booted up perfectly fine in the usual PCI-e slot i always use.

A mod can close the thread now Not a clue why my computer decided this would be a good time to faff around, but we're all sorted now and installing drivers as i type this on my laptop!
