problems with my 7800 GT

post #1 of 4
Thread Starter 
Hello,

The problem I have been having for quite sometime now has been occuring for close to 7-8 months now. I've tried new drivers, new directx drivers, everything that I can possibly think of.

So heres my problem:

I run counter strike 1.6, counter strike source, Day of defeat, Day of defeat source, and all other 1st person shooters flawlessly on my computer. However, the problem occurs when I try to play CoH (Company of Heroes). For those of you who dont know, CoH is a RTS game with high quality graphics. Anywhere from 5 min. to 25 minutes into MOST games, pixels will appear all over my screen, my screen will flicker, and it will lock up my ENTIRE computer, and I will be forced to manually restart my computer. Having said this, my problem does not ALWAYS occur. I have had spurts of time ranging from 2days at a time to a month straight without this problem, then it will come up once again for long periods of time.

Additional notes: Sometimes after i manually restart my computer, and return to the initial boot screens, the pixels will still be on my screen, however, my computer will continue to boot up normally, except with a bunch of messed up pixels everywhere.

Another note that might help, is that I get the SAME TYPE OF ERROR when I try to run 3dmark, which im sure everyone who reads this forum knows about.


I have an AMD Athlon 64 X2 Dual
Core Processor 3800+
2.01Ghz, 1 Gig of ram
Nvidia GeForce 7800




I have a hijackthis.log, as well as a DxDiag.log for those who may need this for diagnosis.

HOWEVER, the point of this thread is to get additional ideas about what may be causing this problem. I think I have found what is causing the issue. I am running this game on the lowest quality settings possible. I noticed my video card was running at about 70+ degrees Celcius mid game ON LOW QUALITY settings. I have 2 fans on my tower, 1 on the proc (obviously), and the fan on the card itself works fine. However, my card was running above 70 deg celc and would crash. In an attempt to try one last thing, I opened up my tower, and put a HUGE fan outside of it, and managed to keep my video card temperature at around 60 deg celcius MAX. I had no crashes, and the game ran fine. I HOPE it is my temperature thats causing my problem.


So, I was looking for a few extra opinions, do you guys think its a bad card? or just a higher temperature....

My card runs at around 48-52 degrees celcius idle, and around 60-64 degrees celcius playing CoH and 3dmark WITH THE HUGE FAN BLOWING INTO THE TOWER.

However, when there is no fan, as stated before, i'm running around 70+ degrees ....

any feedback is appreciated, thanks

Do you have any parts in your computer overclocked? I had a similar problem awhile back while playing WC3, it turned out my RAM wasn't 100% stable. Other than that I would say look into getting some temperature monitoring software to see if anything is overheating, that could be causing it as well. 70C I believe is within the limits of what a 7800 can take, but it seems that bringing that down helped so getting some case fans could do the trick. Do you know what case you have? It could help us help you pick out some fans.

Sounds to me like it's deff. on the gfx end. Correct me if I'm wrong guys, but 70*c seems well within the bounds of the card - so if it's artifacting under load my first guess would be that the card is nearing the end of its life.

nah i dont have any parts of my computer over clocked. everything is set to default. and yeah thats the reason i wanted to post this thread, is because i'm really skeptical about going out and purchasing a new video card, and continuing to have the same re-occuring problem. My software says that without the fan i'm running at around 70-75 degrees celcius, and with the huge fan blowing into my tower, im running around 60ish. I played like 6 games today and didnt crash with the huge fan. So, i'm not going to assume anything and think that its fixed...


anyways i have a friend who has a nice comp and has spare parts i can try out to see what the problem might be, thanks so much for your response man....


any other insightful replies are welcome!
