What Do I Do If My System Regularly Encounters Unstable Situations?

1. Clear CMOS and update your systems BIOS. (This may improve system stability)
   
   OR
   
2. Try other hardware devices, such as RAM, CPU, video card, and power supply.  Make sure that they are not encountering any compatibility issues.
   
   Otherwise
   
3. Backup your hard drive information to a separate storage media, then format and reinstall operating system.
   
   At last
   
4. If the problem still persists, it could be due to hardware compatibility issues on your system.
