Video card over heating?

I was playing a game on my desktop then suddenly the graphics went all distorted, there where these neon green pixels all over the screen shadowing things

I am using a Nvidia Geforce 9800 gt xfx

After i tried to restart my computer the loading screen looked like this

I can no longer open a game to repeat what happened, it says "can not find Direct3d"

Also i found that when i moved windows it leaves this dragging/lagy effect.

I tested some things by using a different video card to start my computer and found that it no longer had those dots from the picture in it.
*was a very old card and could not open a game to test more*

On top of all this i found my video card to be rather hot but even after cooling it with a room fan the lines stay *it seems that it may be permanently damaged*

I have tried updating the graphics driver but it does not seem to work

And the last thing to happen is an error that says "Can not find graphics card information*

Im rather sure its an overheating problem i was just hoping for other possibilities before spending a few hundred dollars on a new one.

Thank you for your time and any help you can give

 

From your description and snapshot I'd concur that your card is permanently damaged.

 

Also i seem to be able to play Videos and watch youtube and the only thing i notice is the lagy window moving. I use VLC for videos

 

I would check overheating. Dust blocked somewhere.

Sounds like it could be a heat problem tp me.

 

If you install CPUID HW Monitor, you can read your Graphics Card Temp there.
Looking in the NVidia Forum there are quite a few users with heat problems with this card.
Replacement coolers are available, not sure about compatibility with yours but worth looking at.

Guys, all due respect but if it were overheating surely it wouldn't show symptoms so early in the boot process, screenshot looks like memory (graphic not system RAM) damage to me?

It is likely that overheating caused the issue but I do think the card has been permantly damaged.

@AdmSirRed you could try taking the side panel off and directing a desk fan toward it, if all seems ok then replace the fan, if the issue still exists you probably are looking at a replacement.

 

Yes wildfire, I do have to agree with you on that score.
Personally I don't really know what is a safe operating temp for a video card.
I have been told that a high end gaming card can tolerate temps of up to 90ºC, my cards run at around 40 to 45ºC on average.
I replaced a card recently on a friends machine that was showing 79ºC and it was knackered, showing similar effects like the one from SirRed.
There are many good cards available well under the $200.- mark.

 

I go along with wildfire. I used A Nvidia GeForce 9800GT card for about 18 months and it packed a sad. It had a large cooling fan assy but it still gave up.
I'm currently running a GeForce 6200 512MB GDDR2 AGP 8X and it's working well.
Like hawk22 said - there are reasonably priced cards out there. Mine was on clearance for $93.00 NZD. Cheers Neil.

 

I just had similar experience with my GF 8600 card.
Have you removed the card and looked at it?
Are the capacitors blown,tops bulging up maybe split?
Wouldn't be the first Nvidia card I have seen overheating problems on.

I have flashing on my display at about 2Hz. Seems to be worse the more things are running in background. The power light at the bottom of the monitor flashes in synch with the picture.

I'll be opening things up tomorrow and checking card/connector seating and blowing the dust off everything, but it might be the video card is beginning to die.
