Ask for anything else?
 
Now, I have no idea what's actually wrong, this didn't start happening till recently after I reformatted.
I reformatted twice after just to make sure and it still does it.
Any videogame I play will run fine for a bit, on any mode.. High or low graphics, and will eventually TURN into a screen like this, and keep running, or sometimes crash.

Please Help?
the "f" word has been censored so you will be unable to give us a link to the photo unless the name is changed.I just changed it, thank you though.Go into display properties/advanced once there uncheck the "enable write conbining" box so it is disabled then reboot.
Ive seen this correct similar problems in the past with Nvdia cards.

And if that dont work
Other suggestions-
Turn off any overclocking you may have done and run the card at its normal clock speed and pipeline configurations.


Go to the Nvidea website and get the lastest drivers   http://www.nvidia.com/object/winxp_2k_93.71.html , download them to your desktop but dont install them, next goto add/remove programs and unistall the existing video drivers.
Now reboot
Computer will start in super low graphics mode don't panic, Ignore the found new hardware wizard and press cancel, click the driver install package you downloaded earlier to your desktop, once finshed installing reboot once more.

Cooling upgrades maybe needed as the card maybe overheating, in that case you will need to get creative and build somesort of fan setup in there or just buy an aftermarket VGA cooler.


If all that fails- get it replaced under warranty or buy a bigger better card like a 6800 or 7600 series Nvdia.Thank you, tried disabling write combining.. nothing.. tried the new driver.. nothing.. Didn't have any overclocking.. I even tried setting my graphics card lower.. nothing.
I posted another screenie after the driver..
Umm I'll try some fans and stuff.. I think maybe my best option is...
Buying a new computer?  Buying a new computer seems a bit drastic.. a new card would probably fix the problem. Does your card allow you to check its current temperature using some utility? Before you spend money on cooling. Also, if you can, try borrowing a friend's card, and trying your card in his computer, to see if the problem still occurs.I just bought this card, I was only running a geforce mx 440 64mb before this.. and the TEMP is running at 36C  normally with a game running it's.. still 36c (GPU is 34C) Problem persists with both cards.
About two hours later, the car is running at 39c and the GPU is 37
