It sounds like not enough RAM, how much do you have? RAM is cheap. I upgraded my laptop with 8 GB for $42. What version of Windows do you have? My crystal ball was unable to tell me.
When i start my pc the first time of the day after around 5 to 10 min the whole pc start jumping, this means video, sound and mouse... i just restart the pc then i can use it for hours with no issue...
I have changed the GPU 3 times so i don't think it is the GPU or well maybe any of you could help me identify the problem.
Thanks in advance.
