Dead 7900GT need replacement advice
 

Right all today my 7900GT has died, I was getting crashes left right and centre, so I then took it out of the pc and carefully cleaned it on on the static pad with a aresol air canister, I then made sure it was seated properly and that all leads was connected, once and twice over.

When I goto boot the pc up everything spins over inc the gpu's fan but nothing to my screen, I am thinking the gpu is dead.

I will have in a few weeks about two hundred pounds for a replacement gpu card for my pci-e mobo.

I am looking for something 7950GT I did spot a 7950gx2 with 1gb onboard memory which caught my eye but cannot find it again on SCAN Or OCUK.

Any help would be nice. I'm posting this from the old P3 Dell Dimension 4100 we have...and boy is it flaming slow.

Re: Dead 7900GT need replacement advice
 

mate your not having much luck with your pc eh ;)

but finding a nice 7950Gx is hard as hell... looked on ebuyer, microdirect, novatech and some others for ya no go.

get a cheapo card now (say 7600) I know its a downgrade, save the dosh that you have and get a really nice and shiny card in say 3 to 4 months

Re: Dead 7900GT need replacement advice
 

This 7950GT is cheap! Linkage

or even this 8800! Linkage

as for the dead card (7900GT) silly question but havce you tried plugging the monitor into each of the DVI outputs?

Also try turning thge PC off and unplugging it from the mains supply. Then wait 5 minutes or hit the power button to get rid of the remaining power, plug it back in and try again - every now and then i have to do this to get my 7900GS card to display...

hope this helps?

Re: Dead 7900GT need replacement advice
 

here is ONE 7950GX2 http://www.overclockers.co.uk/showpr...597&subcat=637

Tho its not that cheap and an 8800 would probably be faster though the dx10 performace of the G80 has a very big ? over it

Re: Dead 7900GT need replacement advice
 

Thanks for the tips all gonna check it out later with the 7900thing, as for a dx10 card I am not too worried about dx10 I would like something which can improve my gaming on Battlefield 2142 for now, until I can save for my next system.

In regard to the computer being left without power for five minutes the computer does spin up and the HD powers up and the gpu fan spins.

Okay well brought pc downstairs been about a hour since I touched it, setup all wires with no ethernet or usb etc and still nothing.

Re: Dead 7900GT need replacement advice
 

does the machine post? have you tried resetting cmos

Re: Dead 7900GT need replacement advice
 

Nope nothing the monitor sits on an amber light ( green normally ) like it's getting zip from the computer, yet everything in the computer powers up, this is what baffles me, the gpu spins up the HD wires into action their is no beeps no voice over no bad noises no smells it just sits there booting up

Re: Dead 7900GT need replacement advice
 

do you get any beeps upon booting the system??

OK i see you don't... have you tried booting with no RAM in it - you should get beeps then...

Re: Dead 7900GT need replacement advice
 

so the machine isnt posting? reset cmos and try.
Im not convinced its the gfx

What were the crashes? sounds like a mobo problem to me tbh and the crashes were a sign of it dying. Could also be psu

Re: Dead 7900GT need replacement advice
 

How do I reset cmos... i've an asus a8n32 sli deluxe socket 939 nforce4 sli

The psu seems fine all fans working and i've no other than a 350watt to try IF I can find it

Re: Dead 7900GT need replacement advice
 

Re: Dead 7900GT need replacement advice
 

Done that to the letter and nothing still all spins up wirres away like normal just the monitor remains on standby.

I don't get this the psu twin fans are spinning the HD wires into life and the rest of the pc works fine.

I've tried with Ram out and only single sticks. I've removed all unneeded stuff from it... I am totally and utterly baffled.

Re: Dead 7900GT need replacement advice
 

Have you tried the monitor with the Dell Dimension?

Re: Dead 7900GT need replacement advice
 

Here's a thought: try turning it off [including on the PSU if it has a switch, otherwise unplug], then take the graphics card out, & try powering on the machine again. If the card's toast then it should give you some sort of error beep, if it stays silent my money would be on the motherboard or PSU.

This might not work, but if it doesn't beep without the card, try it with the HD disconnected [both data & power wires], as well as anything else [except for essential fans], so it's just mobo, CPU, & RAM. If it beeps then my guess would be the PSU is the culprit. If it still doesn't beep, it still could be the PSU, but without testing with another 1 I don't think there's a way to be 100% certain.

If it was the monitor he'd hear his system beep when it POSTs.

Re: Dead 7900GT need replacement advice
 

Yup in fact I am using the tft I use on my computer with the Dell right now.

I have tried the above diagram twice now, and no avail, It must be the gpu I must've borked something up when taking it out :( but it's a fecking price tag I could do without just to find out wether the gpu was the problem.

Just tried with no HD *nothing not even a beep *
Just tied with no ram *same as above*
Tried with no dvdrw drive *same*

All the times the computer and the gpu fires up with all fans yet the monitor gets no visual, the gpu fan wires alive and it sounds like the HD is booting up but I get nothing from the graphics card to the monitor.

Re: Dead 7900GT need replacement advice
 

If it turns out to be the Mobo Mate, I have a Brand new asus a8n32 sli deluxe sitting here doing nothing. Still boxed and never taken out of the bag which i`m selling. :)

Re: Dead 7900GT need replacement advice
 

PM us how much matey low on cash right now but I'm sure we can come to some agreement.

*in meantime guys keep hitting me with ideas*

Re: Dead 7900GT need replacement advice
 

Yeah, but did you try it without the graphics card in there? If you try that & the mobo & PSU are ok, it should beep at you complaining there's no graphics card. If it doesn't, then chances are it's not the graphics card. Having said that I suppose it's possible that a motherboard might not beep in the absense of a card, but they always have in my experience. It's a shame you don't have another PCI-E card to try in there.

Re: Dead 7900GT need replacement advice
 

Right now I have remembered it helps to plug the pc speaker in

*-add ur ****take posts here*---------------------------------


It does beep when the gpu was removed

One long beep three short

Re: Dead 7900GT need replacement advice
 

Dime... bar...? :p:

But nothing when it's in its slot? If that's the case then I'd say your card's toast.

Re: Dead 7900GT need replacement advice
 

Yup nothing just silent with the card in I have to admit was happy to hear some beeps, checked the wise google and it claims the gpu is dead.

Sooooo coming soon a Top Gear styled 7900gt tied to a firework on youtube :D

So whats good for about two hundred quid tops? Would prefer to spend about hundred and fifty as money is tight right now but it has to be a minor improvment on Bf2142 for me...

Re: Dead 7900GT need replacement advice
 

Is it not still in Warranty?

Re: Dead 7900GT need replacement advice
 

Keep the HSF from it though as a spare [assuming it was still running at a decent speed & wasn't the reason why it fried in the 1st place].

Re: Dead 7900GT need replacement advice
 

Yes I bought it from Scan was my first purchase from them, I'm going to see about getting a lift from a friend on here to their Bolton store in the morning, I have no reciept or box for it but heh their is hope as I am skinto till a week this Wednesday.

If anyone has a PCI-E card going VERY BLOODY CHEAP and I mean postage cost lol I am interested.

---------- Post added at 20:40 ---------- Previous post was at 20:40 ----------

I never OC'd the card.

Re: Dead 7900GT need replacement advice
 

Buy a £15 graphics card to be sure.

Re: Dead 7900GT need replacement advice
 

fifteen quid? where do I find a pci-e card for 15quid?

Re: Dead 7900GT need replacement advice
 

This one is around £20 and i only looked for 30 seconds.

Re: Dead 7900GT need replacement advice
 

I normally use Scan thats why ;)

Re: Dead 7900GT need replacement advice
 

£18.79 at Scan http://www.scan.co.uk/Products/Produ...oductID=190650

You may as well go down to your local shop tomorrow and pick something up dirt cheap seeing its just for testing purposes. :)

Re: Dead 7900GT need replacement advice
 

Would if I had the cash :( *sigh* had a huge spending spree when I got paid and never had a thought.... *realises he has twenty quid lying about*

*goes scan in morning*

Re: Dead 7900GT need replacement advice
 

I wasn't implying you had, even at stock speeds a lot of cards would fry if the fan wasn't working properly.

Re: Dead 7900GT need replacement advice
 

Well the fan seems to be spinning up just fine, I am going with defunct GFX now for a few reasons

1) I was getting artifacts on BF2142 even though temps are in the clean
2) I also was getting crashes on other games INC the ultra reliable HL2
3) The beep error
4) The factor this problem only occured after I removed the card to clean it, although I had been having errors on nv4.dsp for a long while now at least a few week, and had put this down to BF2142 having bug issues and I had not been gaming as much in recent days.

Re: Dead 7900GT need replacement advice
 

go direct to the card manufacturer they will know the age of the card and honour any warranty

Re: Dead 7900GT need replacement advice
 

Well I'm giving Scan a go first thing may aswell give them first dip's and see how I go, plus I can grab a cheapo card while there even if MSI honor the warranty I still could use having my pc up and running in the meantime.

Re: Dead 7900GT need replacement advice
 

Well been Scan and the 7900gt come up clean no faults got myself a new PSU unit and when fitting it noticed something.

Before I had not noticed this due to the light, but today while on phone to a friend that something glinted at me from the PCI-E socket.....a single human hair.. was laid in the socket likely fubaring the connection.

So removed it gently and now all is fine.

May the mickey taking commence, and on a plus note my 12v and 5v rails are stable and a new PSU was needed.

Re: Dead 7900GT need replacement advice
 

Log in to the Scan website, you should be able to get old Invoices without a problem

Re: Dead 7900GT need replacement advice
 

kinda cracked it in post 9 ;)

Re: Dead 7900GT need replacement advice
 

All is good and I am back to my gaming ways.

But I still get the artifacts you see in the two shots especially on Battlefield 2142, I have my Windows updated and running a fully legit copy of BF2142, I have tried various gfx settings to no luck i get them randomly on random objects.

It is not really obtrusive but just annoying and a cause for worry as I do get it on Star Trek Bridge Commander yet I do not get it on Half Life 2 or F.E.A.R MP mode.

Re: Dead 7900GT need replacement advice
 

That looks like driver issues to me? Have you used older drivers newest drivers omega drivers if your not on vista?

Re: Dead 7900GT need replacement advice
 

I am using some tweaked drivers from the Omega website they're the latest ones they have.

Re: Dead 7900GT need replacement advice
 

Have you tried running with v/sync on,came across this here

Re: Dead 7900GT need replacement advice
 

I shall try that I was getting the weird glitches on Half Life 2 though and I have that setup....

When I was at Scan they claimed to have run benchmarks and tested it and it was fine, yet with the nvidia control panel temps always in the green max about 59c after gaming ( pc in living room ) and cpu and mobo temps never going to high I am only thinking my card is tired or perhaps my case has poor ventliaton?
