I am using 815 chipset in my computer. The processor I am having is Pentium Pro 350 Mhz Processor. Actually When I am playing freecell or Hearts ( Windows Game) , Machine freezes. No mouse movement occurs. Keyboard is not working. I have to restart the machine.

I have changed several BIOS settings. No improvement on the work. The probelm occurs only when I play freecell or hearts.
I suspect the mouse setup. The mouse is connected on the serial port.
Any of you, Have you ever faced this problem. Please give me a solution.
I am using Windows 95 OS and System memory is 32 MB.
