My PC has games like GTA San Andreas, Counter Strike 1.3, Warcraft 3 Dota All Stars and Kill Switch. Also, I have applications such as, Adobe Photoshop CS3 Portable, Dreamweaver, Macromedia Flash MX, etc. Oftentimes, while playing GTA San Andreas or Warcraft, I am experiencing slow motion movement of my screen. And if I still continue playing, my computer has shutdown, or sometimes, it restarts. I also noticed that my CPU fan is so fast. Are you familiar with this problem? Thanks in advance.
