Make sure you are installing the right driver. A driver for the same looking card that has more ram can be easily mistaken. If you have installed a driver for a card with more ram then it would explain why it is fine until put under load. when under load it will try to use more ram than it actually has and cause problems.

My intel stock that I am using to cool a 1st generation i3 has recently stopped working I have tried plugging it into other fan headers and setting the fan to max speed but with no success, fan has very little resistance when pc is turned on but cannot be spun manually when the pc is turned on. I have done everything I can think of but would like some help/ advice to try and get it spinning. it is installed in an intel desktop board DH55PJ and using an hd5450 1gb for display
