Diagnostic tests are software programs that test different parts of the component.
They may test all of the component, or they may only test part of it.
And, the things that they test may not let it report accurate information
But, they are the best tests that we have.
The ultimate test is to try another, known-to-be-good video card.
1) It may take a while to reproduce the problem (so how long do you wait when trying another video card - when does no sign of a problem = the problem is fixed?)
2) not many people have a spare video card laying around (you can offset this by finding a store that will let you return the test card if it's not needed - and be able to get your money back)
Start with these free hardware diagnostics: http://www.carrona.org/hwdiag.html
Also, monitor your system's temperatures with this free tool: http://www.cpuid.com/softwares/hwmonitor.html
Check the video card for:
- is it seated properly?
- does it have the proper power connections and are they firmly seated?
- is the cooler free of dirt/dust/ect?
- does the fan on the cooler spin freely?
- is the system pumping hot air into the cooler?
