I had built-in video. I wanted to upgrade my graphics card. Friend gave me an ATI Radeon HD 4650. But to do that I replaced my 300 watt PSU with 650 watt PSU (because minimum for card was 450w). And after that I pluged in this card and installed drivers from CD that came with my video card. The problem is, that sometimes while playing games (Minecraft, Euro Track simulator, Crysis etc) the screen freezes for a second and turns black (flickers). Then turns on back again but some games crashes. When screen flickers, ATI Radeon Service poops up and says that graphics card stopped to responding. I forgot that my PC is overheating. When I used built-in video card, the temps were:
AUX 40C System 60-68C
After installing new PSU and this card:
AUX 42C System 65C-69C
If you think that video card is overheating, well no, max video card temperature was 47,5C.
So what can be the problem?
