Graphics corruption

[ch9lss]

Please help me..aargggghhh

I am currently experiencing what seem like graphics corruption on my PC. At random intervals the screen shows lines on it and sometimes the monitor powers down and says it has no signal. I have tried reseating the graphics card but it still does it.
At the moment I have only seen the problem on the desktop and not in any 3d game.
My card is a Point of View 7800gt plugged into an abit AN8 fatality motherboard. The card is barely a month old and I'm pissed that I already seem to have a problem.

PS It's hard to eplain the corruption. Sometimes it's parts of the start menu staying on the screen and sometimes its small lines like =_= and almost always ends with the monitor getting no signal

I really hope you can help

Sounds like a driver issue....did you install drivers from Nvidia cd or allow Windows to install drivers?......always best to use the provided cd.

Also have a look in device Manager to see what drivers are installed.

Could also be a heat issue as this can happen if the gfx card is overheating....do you have sufficient ventilation...dust the pc regularly.....check your temps?

Try running with the side of the case removed and see if that has any effect.

yeh i would suggest a drivers change

i have a XFX 7800GT -my drivers are 81.95 and its perfect

download the 81.95 drivers from Guru3D

I removed the case and it still seemed to happen. As yet it hasn't affected my games so I'm wondering if it might be a hardware fault in 2d mode. The problem started for no reason. I hadn't installed new drivers or done anything to the system, so it has stumped me.

Many thanks for help though

have you tried checking your cards temperatures| they should be monitorable thru the driver panel - my 7800gtx used to chuck up artifacts like that when it got to hot...and the monitor used to go off like yours does - turned out it was just getting to hot...changed the cooler and it worked fine after. do you have a fan on your case sidepanel you could set to blow air onto the card?

Are you running your pc through a switch by any chance?. This has been known to cause some problems so try switching\changing monitor lead.

Alternatively dumb down your refresh rate and see if that has any effect.

[ch9lss]

Might try the refresh rate reduction. The core only registers about 46C on the nvidia control panel when the artifacts start appearing.
I am still wondering if the 2d part of the core is faulty somehow. Can that be possible?

Many thanks for your help

Could be the 2d but it sounds like you may have something externally affecting it.

Have you got any electrical leads running close to the monitor data lead which could cause interference?

Is the lead damaged? Give the monitor cable a bit of a squeeze/flex along its length to make sure the picture doesn't degrade?

Do you have a mobile phone near the monitor that could be causing interference?

If none of the above solve the problem:

Pull the card out of its socket and reseat it - that'll clean the contacts in case it is a build up on the pins. Additionally it will also clean the connector pins on the cable from monitor to card.

If these and the monitor refresh reduction don't work then I guess you may have to return the card (:

I have a spare monitor lying around and tried swapping it over when the problem occured but it still decided to switch off the screen, so I doubt the cable is the problem.
Nothing around the PC has changed recently and the card didn't do this when I 1st bought it, so I am unsure if intereference is the problem.
It looks like I will have to send the bloody thing back. However the problem is intermittent so RMAing it could cause some hassle, but if it is the graphics card and not a different component then I don't see why I should put up with a duffer.

Just a quick update.
I have emailed Point of View to see who I should seek to get the card sorted. I have also seen the same artifacts and corruptions on the game F.E.A.R, although they disappear when you enter and exit the menus.
Hopefully Point of View will be able to help me with me having to resort to their rip off premium rate tech support.

Good luck with that and let us know if it gets resolved and what the problem was

Hello to everyone

Finally sent off my card and Ebuyer have found the fault as well, so I have been refunded my money as they do not stock this card any more.
Thanks for the help you all gave me.

My Hercules Geforce 2 MX used to have 2D corruption like you describe, nvidia fixed it after a couple of years in the drivers. Also, some cards get it when the video card pipelines go faulty. However thats in 3D and 2D.
