Welcome to AT...

You might want to list your computer specs and how old some of the componets are. Plus how long has it been acting up etc...

AMD Sempron 2600+
Asus A7N8X-X motherboard
1 GB ram
nvidia geforce 6600GT

the system worked perfectly fine for about 2-3 years then started to shutdown on its own last week.
