Hello, I was using Acer Aspire XC600 minitower. Just upgraded my system to Sapphire HD6570 (and a 460Watt psu with a new casing) But sometimes when I was playing games the display turns off. The monitor is showing 'no signal' but obviously the pc is still running because I can hear the background music. The display returns after I restart the pc. Also there a couple of times when I was just only browsing the internet and the same thing happened.

Here is my pc spec
Intel Core i5 3330 3.0Ghz
RAM 4Gb DDR3
Graphic Display adapter AMD Radeon HD 6570 2GB
Windows 8 64bit
460Watt psu

I increased the fan speed for the gpu at the AMD Catalyst settings and it solves the problem :) I can play Dishonoured and Crysis Warhead at medium setting for hours without any problem. It probably overheat and causes the display to fail. Anyway I'll add an additional fan for the tower. The the gpu has a rather small fan and heatsink.
