Help with graphics performance issue please

I become the owner of a pretty bad ass PC a couple of months ago. The other day I noticed that when I booted up my PC I got a couple of seconds of static on screen before it got to the windows login screen. Then it happened on a separate occasion where the static didn't go away until I rebooted.

I have also noticed that flash videos have been freezing for a second despite being fully loaded.

Now I am having issues playing TF2. I can be playing for about 20 mins and everything is fine and then the game will freeze and stop responding so I have to manually shutdown the process. This has happened the last 3 times I have played. (anyone else experiencing issues withTF2 right now?)

I spoke to the company I bought the PC rig from a few days ago before I noticed the issues with TF2 and they said that the static could be caused by the gpu drivers kicking in, and that they didn't see a real problem.

What do you guys advise?

On a side note I have looked at my device manager and noticed a couple of warnings next to 2 things but I can't work out what drivers I need to install and if they are having an affect on this problem I am having.

Thanks for taking the time to read my issue and I appreciate any help you guys can offer.

  1. Are you sure you have the latest nvidia drivers? I doubt those things that don't have drivers are causing the issue. How is your fan setup inside the case? Also check to make sure that your cpu cooler is seated if it is only making partial contact it would provide enough to keep the heat down while idle but not enough during load. I prefer to have my cases setup with fans so that the front is intake as well as the bottom while the side is out as well as back and top.

    Yeah I am using the latest drivers 335.23 I have the Geforce experience thing, so that keeps it up to date for me.

    I have the default fan set up for the case I guess as I didn't build the system myself, I ordered it custom from computerplanet.co.uk I think the 2 fans at the front of the case is the intake and then the top fan is the exhaust I think all 3 fans are 120mm they look it. As for the watercooler on the cpu I am not sure really, and am a bit wary of messing with it :S How do they fix onto the cpu? I have never fitted a heatsink of any sort to a cpu before. The H80 radiator is fitted to the rear of the case.

    Is there any way I could monitor my cpu temps while in game?

    Try that one run your game in window mode see if you can't catch it. I'm not sure on that particular setup I have the older h100 which uses screws to attach itself down so you'd have to look it up in a manual or online if you can get it.

    CPU while playing TF2 gets up to 52 degrees celsius while running a stress test it doesn't go above 62 degrees celsius. That is fine, right?
  5. Also the GPU didn't go above 58 degrees celsius playing TF2
  6. OK I have just been playing TF2 and the problem occurred again, game froze and had to terminate the process. I was running the temp monitor program and the max cpu got to was 64°C and the gpu was 61°C. I believe these temps are good especially with an overclock on the cpu.

    Any other ideas about what could be going on? Thanks.
  7. Try settings your clock speeds back to normal on the cpu that could be causing an issue if its not completely stable. If that doesn't work i'd recommend if possible to do a fresh install of windows with just drivers and the game. See if it was an issue with software. Have you tried any other graphically intensive games to see if it is just a problem related to the game? The static on the screen almost seems to me like it could be psu related or something perhaps related to the monitor itself. You shouldn't be getting stuff like that on screen. Other thing might be to give it a really good load test for a couple hours with something like prime95 which would let you know if you are stable or not.
