My problem is this:
In the last couple of days I started playing Dragon Age (great game btw) , and while I was playing the game froze and I saw glitched pixels (green , red etc) and the PC restarted.
I was surprised to see that even on boot , the pixels remained , so I shut my PC down for a while and then turned it back on ,
at which point the glitched pixels were gone.
After that event , the same thing started happening to me over and over in all games , and also while being on the desktop , with the monitor turning black and then returning to normal , at which point I noticed this message:
Subsequently , I tried using RivaTuner to force the clocks at stock (although they were already at stock) and forcing the fan to 80% with no success on solving the crash.
I completely uninstalled my Nvidia drivers , restarted my PC , and then reinstalled Nvidia drivers to version 191.07.
Interestingly , I think I spotted the same crash with the glitched pixels while I was on the desktop with the Nvidia driver uninstalled (although Windows 7 did install some sort of a generic VGA driver) , but without the freeze followed by a restart.
After reinstalling the drivers , I was able to record temps while playing MW2 and while crash was occurring (I was able to "save it" before PC restarted by hitting Alt+Ctrl+Del) the max temp I got was 78 C as recorded by HWMonitor.
If its artifacting, it could be your gpus ram, and it got hot at some point and cooked.
Try underclocking your card, and keep it cool, it may work, make sure the profile is set for underclocking at boot, so as not to cause more harm.
This may or may not work, if it is the ram
Oh I forgot to mention , another symptom of this "crash" is object being displayed in an off color (such as green , purple) or completely corrupted pixels. EDIT: it looks something like this: (this is a google'd screenshot)
@ obsidian86: I bought it at the end of April , 2008. BTW , it was never OC'ed for a long period.
@ jaydeejohn: weird thing if it did got cooked - I was using the current setup for a while now , and it suddenly happened out of nowhere...
Here is something I tried and seemed to stop the crashes:
I clocked everything at stock (ie FSB 333) and removed two DDRII I installed about a month ago , and the problem seems to disappear , thought my PC is considerably slower.
