I'm not quite sure how to describe the issue(hence the title) but through several diagnosis I think the Graphics on the motherboard is failing. There is no add-on graphics, the system is a HP Pavilion P6310Y, AMD Athlon 2, 6GB of RAM, 1 TB of HDD Space. The onboard Graphics is NVidia GeForce 9100. The PC is about 3-4 years old.
What is happening is the screen flickers and then either goes black or becomes a certain color. This happens whenever the PC is doing something involving alot of data(Scan Disk, Virus Scan, Email, Remote Desktop). The harder part is being able to tell whether the computer is crashing or after the graphics fails that the computer is still processing. I'm going go with a no because I have a feeling this could be an overheating issue as well.
I'm not quite sure how to tell whether or not it is.
Another question I have is if it is only the Graphics, would installing a Graphics Card solve the problem? Or will the rest of the motherboard eventually fail also?
