Tested a repeatable problem with a new Gigabyte AMD RADEOPN HD 7870. After about 5-10minutes of gameplay in windowed mode my computer will turn off with no error messages and restart.
The computer is not overheating as I have my eye on Hardware Moniter & Speedfan. Temperatures max out at worst 60celsius.
While in full screen mode during the same games I have no issues.
I recently upgraded from a XFX AMD HD RADEON 4890 and this problem did not exist. The only new hardware in my computer is the 7870.
