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?

  • I think i have fixed my issue. I changed 3D settings from balanced to max performance and now no flickering. I have tried to install newer driver, but the program sad that something is missing, and when i tried to reboot, blue screen appeard. :( i didn't read it, but everything seems to be working and my motherboard isnt overheating anymore :)

The most likely cause of the flickering is an issue with the graphics drivers. You mention that you installed the graphics drivers off of the CD. These are often out of date. Your best bet is to head over to AMD's site and download the newest drivers for your card and OS. AMD Driver download site

I am not an expert by any means with over/underclocking hardware, but this looks very suspect to me:

GPU Clock 165 MHz (original: 600 MHz)

When the driver says "the graphics card stopped responding" that usually means it hung, or it thought that it hung. I easily could trigger that popup by running a complex graphics program on hardware that essentially was very slow for it. Since it looks like your graphics card is severely underclocked, you'll get a big performance hit, and so it wouldn't surprise me that when running Crysis on that system (a Pentium 4 to boot!) you would experience that behavior.

  • It overclocks it self. Maybe this is the prob, but how can I fix it?

    No, it is not overclocking itself, rather the opposite. Graphics cards underclock themselves when not under heavy load to reduce power consumption and heat generation. This is perfectly normal. All graphics cards do this. Just because the graphics card is reporting reduced clock speeds when at the desktop does not mean it is underclocked while playing a game.

  • I wanted to write underclocked :D

  • @Mr Alpha That makes sense.

  • @Robrok Since this isn't the answer, you should probably uncheck it. :)
