About mid 2006 my cousin took me to MSY, a computer shop in Australia where he selected parts and MSY put it together for me.
I am really not very good with computers and there dyfunctions so I came here.
In the two and a bit years I have had my computer I have had very little problems. But recently it all gone to sh*t.
Ill first post my specs:
AMD Athlon(tm) 64 Processor 3700+@ 2200mhz
NVIDIA GeForce 7900 GT
2G RAM (not sure which type)
i am running windows xp home edition.
I mainly play battlefield 2 online as my computer cant run much other games at high fps anymore. About two months ago different parts of the game started going wrong with "shimmering" i think its call and just huge strips across the screen.
I did the 3Dmark test and these were the images i got on the first two tests.
I did the 3Dmark test and these were the images i got just on the first two tests.
its the exact same in battlefield 2 except it just get worse and worse and u end up being unable to play the game. with it sometimes crashing. i have reformatted the computer and try it again and it did not work. there are no viruses on my comp or spyware and i have tried playing with new gfx drivers, old gfx drivers and no gfx drivers. i got told to run speedfan and i did, these are the results i got.
Ok, just so you know, a gpu core in the range of 50c is very good! I've heard of the x19xx series cards going over 85c and that was acceptable. Sometimes, I have my 9600gt going over 60c and that's considered normal.
What you showed in those pics look like artifacts which are a sign of errors in the gpu's calculations. Usually that means your card is dying or just flat out overheating. instead of using speedfan, try gpu-z. Run that and see what your gpu is at for temps. I suspect that speedfan is giving an improper reading.
also, does your rig do fine under normal 2d apps? I.e. no gaming, but in windows? If so, then it does sound like your card is on the way out.
What is your psu? If you have a junky psu that isn't powering everything enough, then that could also be the culprit. If that's the case, then you can probably buy a new psu and pop that one in. Over time, psu's wattage goes down because of aging in the capacitors. although this rig is fairly recent, like my own.
First, i'd run the gpu-z app during a game and recording the temp, then while you are surfing the web.
Second, try underclocking the graphics card to see if that solves the problem temporarily and check the psu wattage and brand (post here).
Third, i'd try a new psu.
Fourth, probably a new graphics card is in order.
it was an inbuilt psu that came with the tsunami case. I think it might of been 350w ... 400w. sorry not sure. how can i check that? the guy said it was just enough, so yeah, that could be the problem. but does that mean because its inbuilt that i will have to buy a new case and a new psu? or is there a way of taking it out?
It runs fine when its come to running windows, or under no use of games. the only thing that happens is sometimes little pixels go different colours down the screen, if i like scroll.. i couldnt take a screen shot because you would see enough detail to see them. but i can on my monitor. its not my monitor because when i move the pixels change different places. and that only happens sometimes.
ill run he gpu-z and get back to u... thanks for the replies, keep them coming.
It's probably dying then. Try downclocking the card. If you downclock it and artifacts don't appear, then it's time for a new card. An 8800GT (also called the 9800GT) is a good buy right now. If you didn't want to spend too much money on it though then you can go with (in order of descending price) a 9600GT, a 9600GSO, or a Radeon 4670. Since your processor is a bit outdated there isn't much point in picking up two 8800GTs(9800GT) or two 9600GTs and running them in SLi since your CPU will be a limiting factor. Of course, if you can get two 9600GTs for less than a single 8800GT then go for it.
note::: if you do upgrade your video card to say an 8800gt class card or even better,,you will have to also consider upgrading your cpu,because it will seriously bottleneck any new card,and of course you will also need a new psu,in other words ,,it's pci-e time,
unless of course you can find another 7900gt,they are around but are really expensive,here in north america they go for around $200.00,when and if they can be found,scarcer than hen's teeth,one more thing,make sure that you do not have a lot of junk running in the background,that barton is a good cpu but it is still only a single core,and all the help that you can give it to do what you are focused on will help..
Sorry, but I dont know how to downclock the gfx card. Can anyone help me there?
And to the person that want to know the exact card I have. Its a Nvidia XFX 7900gt/gto.
Oh and to the person that said he heard that they give out pretty easily, I am happy with the thousands of hours gaming it gave me last year and a little bit this year.
... to the person that said have you removed the gpu. do you mean have u moved the actual card?
I have not bothered to do that because i have no card to replace it with to see if it works..
I really dont need an amazing card, just one similar or slightly better then the 7900gt. This time next year after my final year of uni i will be able to maybe get into some gaming. i just dont want to go buy a card and then find out it a psu problem or something.
I still would be interested to find out what the problem so keep giving me advice... thanks for the help so far...
I like the HD4670 or 9600GT idea. You can get a really good upgrade for around $80 if you look around. I would take this opportunity to step up your system so that you can play newer games that come out. Coming from the 7900GT, you don't have to spend much to improve your graphics.
If you cleaned out your entire system and did a fresh install and still get the problems there is a pretty high certainty that your card has just reached the end of it's life.
I think JayDJ is probably right. If your GPU is running that cool I think it is pretty safe still but the VRAM may have reached the end of it's life.
one more thing,,you could remove your card,take the fan and heat sink off and clean both surfaces and put on some new tim ac5 ,for instance,there's only four screws to remove,just be very gentle but firm when separating the heat sink etc from the card,also while you are at it clean the contacts with a clean eraser and brush off the contacts..
now then if after all the above suggestions there is no improvement,,,, well,OTOH there is no technical reason why that system should not work happily for quite a while yet,can you test it with another psu..
