So I recently got a new computer and every now and then when I run games the computer basically freezes. (The display shuts off, the sound loops, and I have to shut it off) I have a Lenovo Thinkcentre 7522J4U, here are the specs:
OS: Windows 7 Ultimate x86
CPU: Pentium Dual Core E5300 @ 2.60 GHz
Memory: 2 GB
Video Card:Intel G41 Express Chipset @ 782 MB Shared RAM
