Solve : graphic card dying?? |
|
Answer» Hello, What I am suspecting, is some kind of "degenerative disease" of some component of the graphic card, that would be exacerbated by overheating. That sums it up. You tried drivers and it did not really resolve the issue. Dust and heat can cause permanent damage. On not. Here is something you can try. Bit the laptop in your refrigerator for an hour. Cover it so that moisture will not enter. DO NOT let the laptop get down to freezing. About 50 F or 10 C is enough. Now turn the laptop back on and notice if there is a noticeable improvement in normal boot mode. If so, then yes, it is a over heating problem. The logic to this is that it will take longer for the GPU to get to the critical temperature where is fails. This is not a cure. Your GPU has a thing internally called 'thermal runaway' and happens after damage is done to the silicon. If it was a desktop, could try extra cooling, but not easy to do on a laptop. Here is a video. This guy says it is easy. I don't believe it. But see for yourself. How to remove and install a laptop graphics card. (Part 1) Yes...Someone on the chat suggested that I should also use a better paste that the one I used when replacing the thermal cooling assembly (a silicone paste, white in colour: better use arctic paste?). I will do both of them at once (the paste and the fridge), and yes, maybe it will start in a better way. What I do not understand yet, is how a GPU can be damaged (irreversibly damaged) but still work sometimes. Is it a matter of the distance between conductors, that allow tunneling effect at higher temperatures, but not on lower ones, and the max temperature getting lower and lower? So it seems this laptop is beyond durable workaround. It will teach me 2 lessons: first, get 5, not 3 years of warranty, and second: clean your fan more often! Thanks for the reply, it puts words on it! And by the way: I cannot replace only my graphic card, as it is integrated together with the motherboard, on the same card! And the GPU chip cannot be taken off on my motherboard from what I saw...maybe I'm wrong...Dell Latitude D830 motherboard is about $200 as a used or refurbished item. They have a limited warranty. The CPU has built-in protection to prevent thermal runaway. Plus it has a fan. And you can replace the CPU. The Graphics processor should not generate as MUCH heat.Dust will shorten the life. Dust impends air flow. Tao bad they don't put fans on laptop GPUs. Maybe soon we will have mobile devices with better thermal control. Are you interested in Thermal runaway? Some of the research gets kind of deep. Here is a sample of what they want to do: Quote Abstract— Preventing silicon chips from negative, even disas-Pretty heavy stuff. EDIT: That link is hard to find. Here is another that sounds like your problem. Notice they focus on the CPU and ignore the other overheating issues, such as the GPU overheating. http://www.howtofixcomputers.com/forums/dell/dell-inspiron-1525-overheating-296811.htmlAbout motherboard replacement, I came to the same conclusion: it costs far less than a new laptop, and if I use good thermal paste with regular cleaning of the fan, my laptop should last this time. The problem is: I am afraid of compatibility issues. Like: will my processor (T7500 core 2 duo) fit on every D 830 Motherboard? will the GPU always be aligned with the cooling assembly I have? Will it always support my WSXGA+ screen (1680x1050)? On all the links I saw, the said nothing about such compatibility...And I cannot make dell tell me the dell part number of the motherboard I already have (this way I could be sure). Is there a spot on the motherboard, where this part number could be written? Or some hardware recognizing utility on the web? Once I am sure, I buy the motherboard, the thermal paste, and then pray whatever computer god that all my guesses were right... BTW thanks for the link :-)In my opinion you are throwing money away resuscitating a laptop for any reason and looking down the road for things to get better or stay the same is wishful thinking at best... Others here may have differing opinions however...I have thought about that. Although this laptop is old, it has a lot of advantages, modern "cheap" laptops lack: - a good screen with good resolution, good refresh time, very clear, you can see everything _ really everything _ no matter what angle you are looking at it from; - not bad calculating power - The Gpu, when working, can cope with 60 fps HD videos, works well with Cinema 4D and other stuff, - the system is still XP and works well (I have some science computing software that would not work on Seven) - I recently purchased a second battery - and...I won't have enough money to buy a new good one, before 2 months! Because of a hole of 3 months with no income at all...and this computer is also kind of my workstation (I have a computer at work, but a PC: I like taking my data with me, like in the train as I travel every weekend, or at home, and I have no PC at home!) And compared to all that, now I understood the problem that killed this laptop, for like 200$ I could refurbish it...if I find something trustful, why not!EDIT: after a useful lshw command on a live cd I have (pretty useful command, this is), I knew everything I needed to know. From my motherboard part number (OHN338: apparently Google too hears it almost for the first time, and never heard of resellers), to the true name of the enemy inside my PC: the G86M chip. By browsing about that I found a lot of complaints about overheating, even someone who had his motherboard changed 5 times because of that by dell (he had warranty of course), until I stumbled upon this: story don't know how reliable this is, but this might explain a lot...about precision laptops failing the same way etc...or maybe it is just today's laptops that always want a too big graphic performance for the cooling and thermal stress they can afford...So, maybe you're right about that motherboard stuff, maybe it's still too much money for what it is...I will keep searching just in case, and just to try out, but this is quite embarrassing...I did not want to buy a cheap computer just to link today and in 4 months time when I will have all the money needed to buy a true good laptop...But *censored* if I can live with no PC for all this time!Thanks for sharing your research. The reference implicates that you will have the same issue again with a replacement motherboard. It seems THET the designers did not pay enough attention to thermal design. Here a a partial quote of the three-year-old article: Quote All Nvidia G84 and G86s are badQuote from: patio on October 27, 2011, 02:51:53 PM In my opinion you are throwing money away resuscitating a laptop for any reason and looking down the road for things to get better or stay the same is wishful thinking at best...If you can fix it for less than $100, then OK; otherwise, I agree with patio, new laptops have never been cheaper. |
