What you have said is very possible. I have experienced that stuff personally. koolkat77
suggested me, after checking my system heat and some other stuff) to abandon the graphics card. Well, that's my story
You do four things.
- Use Speccy to monitor your system heat, including the GFX card's heat (specially just before the crash, if possible)
- Open teh computer, clean the accumulated dust very carefully.
- Update the graphics driver to latest.
- Video Card - Stress Test with Furmark
After doing the four, if still crashes -
- Use the onboard graphics to make it sure that if it is caused by the card itself. In this situation, we have to blame the card itself.
In my case, all gone against, and finally I changed the card (one sweet story is there behind it) and now everything is normal.
