Hi, hoping for help. in the middle of playing a game, my monitor got all these pink LINES going from left to right across the screen. (looks like a heart monitor). went into device monitor and there is a yellow mark next to the video card. According to driver detective the drivers for the nvidia GeForce 8800 gt needs upgrading. went to dell, and there is no upgrade listed there. Went to Nvidia and they show an upgrade, tried to upgrade with the driver they said it needed but no difference.  Tried uninstalling the drive, rebooted it put it back in and still has the yellow mark.
Should I pay the price for Driver Detective to install the driver? or is this a dead card?  do not want to pay for the Detective if I will need to buy a new card anyway.
Any advice will be welcomed
Thanks DebbieSince I don't know what make or model your computer is but you did indicate monitor so I can only assume it is a pc not a laptop.  Have you tried hooking a different monitor up to the pc to rule out the monitor itself?NEVER pay for drivers...or any app that pretends to find them for you...it's a scam.

Drivers are Free.Just noticed it's a Dell...
Travel to the Dell site ...enter your Service Tag # from the PC and all your drivers will be listed.
DLoad and re-install the APPROPIATE driver and re-boot...if still the same then the card/chip may be failing.Sorry the computer is a Dell XPS Demension 630i,  I do not have another monitor I can switch it out with. 
I did go to Dell,   Guess it is the card/chip. I was soooo hopeingit was something simple   Did you re-install the video drivers ? ?YES I re-installed and when that did not work I tried to update the drivers. no difference.Just a thought.  Before you go out and buy another video card try downloading a free program to stress test the one you have.   I don't play games but it is possible it might tell you something about the GPU.  Sorry, can't even tell you exactly what to look for.  Probably temps.  Maybe someone else can be of help here.

 http://www.ehow.com/video_4445594_test-video-card.htmlibfox1, I would like you to read (totally) this link. It represents extensive dialogue between one PERSON's seems to me same issue as yours and the evolution of attempts to resolve it with primarily the assistance of one other forum member. It details very well all the things that could have contributed to the problem. That part may serve you to see if you have tried all of them. The good news is that the problem was resolved. But don't jump to the point where it becomes solved because YOUR solution may lie somewhere else along the process.

Good luck,truenorthAnother couple of things you could try is checking the connections on your monitor.  What size is your PS?  Might need a bigger power supply for  the nvidia GeForce 8800 gt.  ibfoxy1, have you tried reseating the card? (taking it out, putting it back in)
