Posted: Mon, 31st Aug 2009 10:18 Post subject: Need urgent help with 8600GTS |
|
 |
Hi!
I have a big problem with my video card that needs a really fast solution. So it's a Galaxy 8600GTS 256MB with the pretty big original heatsink and fan.
It started yesterday, when the screen got corrupted and after a while the pc reset and right from the video card's post screen the text on the monitor was jumbled up and the boot logo had black vertical lines in it. From here on the picture stays the same with the lines, it looks like an old game like C&C in a very low resolution.
The video card is stopped by windows 'because it reported problems. (code 43)', the resolution is around 640x480 and I can't change any display realted settings.
As I have only installed win7 on friday I don't have any games installed so I don't think that it is an overheating problem, the card should be in 2D mode. Also I cleaned the rig on friday so there's only a little dust on the card where I couldn't reach because of the electric components on the PCB. Also it was turned off for 9 hours at night and it still has the problem right now.
I can't start the nvidia control panel because it disappeared because windows stopped the card. I ran however gpu-z but apart from the original specs it can't return any current values. The card was never overclocked (factory oc-ed though), and the monitor works perfectly.
Thanks for reading and I hope someone can help with something other than return the card (I still have warranty on it).

First take apart your rig and clean your fans thoroughly. You can buy canned and pressured air (if we have it here in Cro then you should have it too ), it's not expensive. Then put it back together and try to start it.
If that fails I guess that memory on your GFX is corrupted, or it's getting pretty hot (there are apps for monitoring that).

There's a point before windows starts where it says 'Checking nvram...', but there are no errors. I tried a video memory tester but it can't change display settings so it can't carry out any tests.
I wonder if the temp monitoring apps can show any data...
In the afternoon my father brings home his temperature scanner so I can at least get some info with that.

The GPU diode constantly shows 60°C.
Maybe it overheats but it has to happen right before it shows the post which is weird, I think.
I have two DVI connectors at the back, but I will try to connect one to the monitor's vga port. Though usually the digital ports are the ones that make the artifacts go away.

I can't believe it but it works. I connected the monitor's vga port to the one I was using before and the DVI connector to other DVI on the card. Now the desktop is spanned and both half is displayed correctly.
Yet I'm afraid if I connect it only with the DVI the problem will come back.
Temp went down to 50°C

I've tried Video memory stress test 1.7, it works like memtest86 but it's for video memory. There's an option called Ignore colors bit mask. If I uncheck it, there are no errors, otherwise there are more than a thousand of errors and it says that I should try to uncheck it.
The temp is constantly at 50°C.
I can't think of anything else so I will try a restart with only the DVI cable connected to the monitor, but on the other port that I was using before.

Dammit it's back again, tried both DVIs with VGA and DVI aswell but the screen is still crap.
I've tried logging temperatures while playing CS:Source but the highest in the log is 56°C, although the last 5 seconds are missing:
Mon Aug 31 13:19:03 2009, 10 %, 23 %, 55 °C
Mon Aug 31 13:19:04 2009, 11 %, 23 %, 55 °C
Mon Aug 31 13:19:04 2009, 11 %, 23 %, 55 °C
Mon Aug 31 13:19:13 2009, 10 %, 23 %
Seriously WTF??? It can't be temp problem, the connectors and the memory is fine so I can't think of anything else.
Could it be the mainboard? It's an ASUS P5K Pro.

Could be... have you tried switching from one to another PCI-e slot?

Oh, hmm... not quite sure :\ You don't have guarantee for that? It's better that the people at service break your rig than you
I think it should work but it won't use it's whole potential...

I built the computer but I bought the mainboard and the videocard at the same place and still have warranty on both.
It looks like I have to go near the shop tomorrow so maybe I will take it in.

I dont know whta the fuss is about, it seems pretty obvious to me the card is fubard, get another card in there for this test..
If you have not fucked about with over installing drivers, and uve been using a clean OS, then the above is probably even more true...
Temps mean shit when it comes to a card going bad.. new/old dont matter cards die when the components decide to die lol... can happen even right out the box after buying one..
Still I say borrow someones card to test, or you could end up going in circles for a long time.. not to mention the intermitent working then suddenly gone bad again, says to me again bad card.. They have a habbit of corruption then suddenly desktop is all well, play a game it blue screens or image corruption..
Or you manage to end task on a locked up game but desktop looks fine.. sometimes using internet explorer will show up line corruption when browsing etc but rest is fine to look at... Strange shit happens with cards when death is near...
Anyhow 8600, its a good bet its time for a upgrade anyhow

Thanks!
Well, the good part is that I bought it at one of the cheapest shops, so even if they say that I have to choose something else it's alright. The warranty ends in january so the question is if there will be another price fall because of the new nvidia cards coming out in the next months?
I payed ~$150 for the card so for a few more I can get a GTS250 with 1GB memory, but I will have to read some hardocp tests to see if it's worth it or I should wait. Th BFG revision B looks gr8: http://www.bfgtech.com/bfgegts2501024ocbe.aspx

Just be carefull, few years ago I had problem with DVD and I decided to upgrade to DVDRW, but I had to pay the difference, price of the DVDRW from time when I bought DVD...

My experience with two other shops was that they would replace if they had the same model, else you could choose anything else they had (not even have to be the same type of item) and if there's a price difference you have to pay it. But they would NEVER give back money.
Once my old samsung 4x DVDRW, which I bought at a super market like place (Saturn), stopped writing properly, I took it back. A woman behind the counter asked what is the problem with it and I said: -It wouldn't write. And she filled out the documents and gave me the 'coupon'. But in those days RWs were half the price, so I bought my current Pioneer and a lot of empty DVDs and I had to pay ~$2.5. (Also, we bought the samsung RW in a governmental program and this way we even got half of it's price back).
But even though this is one of the cheapest places they are very customer friendly, so I think they will even offer giving my money back, but I will definitely buy my videocard from them.

I think you have one of the bad nvidia chips. They released them a few years ago, made them with the wrong solder type...and when they get hot, the solder melts. I've gone through 3 on my laptop (has an 8600M GS. Glad to have an extended warranty) and the wife's laptop just died 2 days ago with an 8400M. (No warranty..had to buy a new laptop). They did have these 'bad' chips in desktop cards too, it's just that since the desktop cards usually run cooler, they didn't have as much of a problem with them. The bad news is there isn't any real "fix" for it..the chips are bad..period..nothing you can do but replace them. Do a search for 'nvidia defect' etc and you'll see what i'm talking about.

Yeah, thanks, I've heard about this, but there weren't too much specific information. Only speculations and probably some lies. I thought that if I had the problem then my card should be overheating, but now I know that heat is the cause of the problem and it happened only now because my card's got a Zalman VF900-Cu on it so maybe with a mediocre cooler it would've been hot and stopped working much earlier.
