Hi all ,

Suspect my card has unexpectedly died , really disappointed but things happen. Just wanted a few confirms or ways to totally confirm its dead.

I basically fitted a h80 cooler bought from ocuk. Removed the graphics card correctly sliding out perfectly. Fitted the h80 ,,, eventually. Put my card back in slotted in fine. Connected up the hdmi, power pin and powered up.

No boot. Just h80 whirring loudly. That's odd. Checked the connections , 7850 powered and all well. Amended fan setup on the motherboard for h80 then attempted to boot again.
This time system span up fast the slowed down to manageable level. Seemed from the led's system was booting. But nothing on screen at all. 7850 was spinning perfectly , both fans and power connector fully pushed in. I was stumped.

I then tried booting from the motherboard connections. It booted. I went into the bios. Checked the graphics options as it was going to use the igpu I guess. It did show PCIE x16 lane - x0. Which began to worry me. I then grabbed the only other graphics card I had a 5570. To see if the mobo pcie slot was faulty. But it booted first time. So now the 7850 is looking bad.

That's where I'm up to. I've contacted the seller from the mm I bought it from to see if he can help me RMA. I will look to try the card in another system today to see if it works there.

Is there anything else I should test or do before I accept this is dead.
 
did you try the second pcie slot if you have one?

cleaned the gold contacts on the 7850 where it slots into the mb?

Hi wazza ,

Cheers for the reply mate. :)

Yeah been doing that this morning ( cleaning the gold contacts ). All good and clean it seems to me. :( :( I am using mini itx so one and only PCIE slot im afraid.

Again i tried the 7850 in the system. using all the out options , HDMI and DVI even VGA to DVI and nothing. No boot.

One other thing i will add is , that upon re-installing this ghastly 5570 as windows boot appears i get a message screen. It stated " startup failed " and gives me the options to " start windows as normal " or " repair startup tool ".
If i just boot it works fine with the 5570.

I also checked in the bios , where the system detects the lanes and bus. It shows 8x for the 5570 as apposed to 0x on the 7850 when installed. :confused:

This is not looking good. Any other pointers or tips welcome.

Yeah ill check again , anything is worth a try mate.

Just tested in a friends pc , screen flashed a few times keyboard lit up and looked liked it was going to post. But it didnt and kept restarting the system.

New Card --- Same issue ????

Ok guys really need all your help here. :confused:

As per the rest of the thread i concluded my 7850 was dead. So its in the process of being sent back RMA.

Anyhow , could not wait around so bought a brand new card HIS ICEQ 7870 2048MB from ouck on the one day only sale.

The problem is i got the card this morning , carefully installed it in the system. (Its not hard and i know what im doing). :( Connected everything including the two 6 pin power connectors required and booted up pretty happy ............

BUT NOTHING !!!!! WTF :mad:

System does not post. Similar to how the 7850 was showing ... ?? I admit the fans were a bit off when trying the 7850 , but this new 7870 span fine and the system leds flashing and the sounds felt like it was booting into windows but nothing on the screen. Nothing ODD to me.

I took out the hdmi ,, tried vga to dvi and still nothing. The system was working fine with the temp 5570 installed. ?? So cant be a slot issue. ?

I am now using the IGPU on my i7. It booted first time. Went into bios and altough the IGPU is being used its showing the PCIE lane as 0x as it did with the 7850. But is this due to me using the IGPU though. Surely this card cant be dead as well.

So please any help appreciated. I not only lost a 7850 ,, but cant use the 7870 I have shelled out on either. :mad:

Kind regards

Hi noob cannon ,

Well it seems to work fine when without this gpu. Using either a 5570 or the igpu it boots and works fine. Just when I use either the 7850 or the new 7870. I'm using a cooler master gx650 psu.

Thanks

latest motherboard bios? seems strange the new card wont work either

Yes mate, the very latest.

I am thinking the exact same. Surely I can't be that unlucky. :( got to be something else. But I've tried all the bases you would start that I can at the moment and its not posting like the old 7850.

I am going to a mates on the weekend he has a i7 920 system and a 850w psu so going to try it there before rma'ing. I just really pi***d at the moment.

Any other ideas or theory's welcome ,, ill give it a go.

did you try booting up with onboard graphics,then in bios set to peg or pcie

save/shutdown pc then install the graphic card and bootup? sometimes there's a fault with the auto detection when a gpu is installed
 
You might need a complete bios reset. Ive had this issue myself and thought that the gfx was dead. Did a complete reset meaning deplugging the power cable and removing the UEFI battery and then left it for 30 minutes to "derage" :P. After i plugged the gfx back in and the power cable and the beast was alive and well again.. I hope its really this simple for you as well.

Cheers for your input.

Thanks a lot. I got nothing to loose so I'm going to try this now.
 
Well I had a go ....... unsuccessful im afraid.

There was a bios update available wazza , so i updated it. One of the improvements was that of pcie graphics cards.

I also removed the bios battery for nearly 25 mins.

Firstly after removing the battery no boot on card. So i then went back on igpu and booted into windows. Updated the bios to 1004 which is the latest.
Went into the bios and made sure of the change. Changed the first display to pcie and shutdown. Changed the hdmi to the 7870 re plugged the power cable back in and powered on. No visual post. One thing i did notice as i mentioned before the system looked liked booting. Hard drive working was flashing like normal. So when i had to power off and replace the hdmi in the board , on normal boot into windows again i got the " Windows failed to boot " error message and i chose boot windows normally. In which it did. Does this not say the system is posting in some way ? Just not so that i can see it. ? Or am i just hoping ........

Damn thing

you've tested with dvi/vga ports if your monitor has them?

Hi Wazza , Tested with a vga to dvi cable and same result. Im using a Toshiba 42" HD LCD. :( Only have this and hdmi inputs im afraid. :confused:

I am begining to think im just seriously unlucky this week.

Thanks for all the effort mate. Appreciate it. ;)
 
I can't think of anything else,other than setting to peg gen 2 mode in the BIOS for the graphic card,I think it might be a BIOS bug or could be BIOS/incompatibility issue with your tv,ill ask stasio to see if he knows any more recent bios's

Hi all,

A interesting update.

Ok took the new card to test in another machine. I plugged it in same as i did in my machine. Did not notice any difference of seating or anything. Plugged in the two power supply pins and booted .........

It posted !!!! Went into windows and everything. Card sitting at 27degs.

I'm absolutely like WTF mixed emotions. I mean it works ,,, but now the hard part why not in my machine.

Just to confirm I just also tested the dead old 7850 too. ......

Yeah you guessed it...... Posted as we'll.

:confused::confused::confused:

So the information so far as to find out possibly why.

It's not a TV LCD issue. As tested today with a very old 50" plasma and worked fine. My LCD is full 1080p and worked fine with the 7850 previously.
I am using a coolermaster gx650 power supply. My dad's is a thermaltake tough power 850w psu with quad rail. Could this be a possible issue ? Though prior to this it was enough to work.
Other option is motherboard ? Have I done something to the pcie lane ? Damaged it somehow ?
But how comes it works fine with the 5570 card installed ?

Since getting home I tried again and same no post. But the PC is booting. The keyboard is active I can turn on caps and num lock so ideally the PC is on the welcome screen if windows. But no visual.

I'm going to up trying different things tonight so any ideals welcome.
