GT 540M Problems

Hello, i am having problems with my graphics card GT 540M i don't know why but it's become really slow, like i play Far Cry 3 on lowest settings and average 10-20 fps when on youtube i see people with the same graphics card average 30+ fps, i have no idea what was going wrong with it, i bought an external fan which i place under the laptop to cool the cpu, right now i have got FC3 on but not playing (as i am writing here lol) the temp is 80%, the 540m temp is 73% and the intel hd graphics family temp is 88% (no idea why that is high, only applications i have on are fc3, gpu-z, ds3 tool, cheat engine (don't judge me lol) and mozilla firefox), so i don't see what is wrong, i have also updated the graphics card to newest version.

Every time i open gpz-u it says Intel OpenCL driver bug detected, skipping OpenCL detection. Please update your Intel OpenCL driver to re-enable this functionality. < is this like a really bad error?

  1. I also have intel i5-2430m 2.40ghz and 8gb ram if this helps
  2. Looks like you're running the game using integrated graphics. I'd try to run it by right clicking the shortcut, and selecting to run with "High performance nvidia graphics adapter".
  3. No, i am definitely using the nvidia card which i do for every game from the way you stated
  4. What GPU usage does GPU-z report for your GT 540M?
  5. well memory usage (dynamic) is 21mb and dedicated is 199mb, for intel graphics dynamic is 111mb and dedicated is 12mb
  6. I meant GPU load, not memory.
  7. oh sorry haha, gt 540m is 0% and intel graphics is 2%
  8. And maximum load for them both?
  9. well for gt 540m the gpu load stays at 0% and for intel the maximum i have seen it gone upto is 5%
  10. You're suppose to look at it when you're gaming/lagging.
  11. ohh in that case the maximum load is 63% for gt 540m also to state the temp has gone to 91'C and for intel graphics the max load i have seen is 8% and the temp is 91'C
  12. What is CPU temp?
  13. CPU Temp is 88'C
  14. When was the last time you cleaned your PC from dust?
  15. It's a laptop so i wouldn't know how to clean it from dust
  16. You should be able to open up the bottom panels. All of the laptops I've seen only required a screwdriver (except for Apple's newest laptops).

    BTW, don't let the cooling fan spin too much if you're using compressed air or a vacuum cleaner. It may become damaged.
  17. I don't know, it might be a risk if i open in case i bust something, and i don't have any compressed air at the moment
  18. Hey, just checked, unlike other laptops where there's a certain panel for the cooling fan, mine requires to open every screw and open the laptop up, i really do not want to do this in case i mess something up on the motherboard
  19. sorry i meant to say open the whole laptop up, this is way too risky for me, so is there any other way to clean the dust, or is there another problem that might be causing the lag
  20. I'm pretty sure it's overheating. 88°C is very high for a CPU.
  21. So do i have to go to a shop to get it checked out because i don't have the experience to fully open a laptop up, well saying that, this external fan is preventing from completely overheating and shutting down right?
  22. dude you are supposed to just blow compressed air through the fan outlet and inlet on the exterior of the laptop. no need to open it up like you say.
  23. Ohh right i just said it because on what A Bad Day said, but okay thanks, the cooling fan underneath and the fan that blows the heat on the side that's what you're talking about yeah?

    Don't do that. You might damage the fan that way.

    @OP: If you really don't want to open it yourself, you could contact the warranty service and tell them the laptop is overheating. They would clean it for you.

    you can do it without spinning the fans up high though.

    Okay i might as well do that i don't want to risk damaging anything, but you're sure that is the problem of the lagging yeah?
  27. One cannot be 100% certain of anything, but I think that it is the problem, as CPUs slow down when overheating to prevent damage. And 88°C is high.

    If you're not going to clean it yourself, we should do some more trouble shooting. Could you check your CPU usage during the lag?
  28. Yeah sure, the only way i know how to check cpu usage is task manager but im sure that includes every other app in its usage, but anyways during the game the highest it had gone to is 70% and averages around 55 id say
  29. Could you check what is actually using up the CPU by opening Resource Monitor (it's integrated into windows 7), CPU tab and sort it by Average CPU? Then, play a game and after ~10 mins just check the list again. Report the top 5 usages.
  30. Okay here are the usages
    1. Far Cry 3 - 50 average
    2. System interrupts - deferred procedure calls and interrupt service routines - 8 average
    3. system - nt kernel & system - 7 average
    4. firefox - 1.7 average
    5. perfmon - resource and performance monitor - 1.5 average
  31. Okay. Looks like the CPU is overwhelmed. I'd suggest you play with settings. Increasing some settings might shift the bottleneck from CPU to GPU and thus increase your performance. I'd test many combinations.
  32. Thanks, there's an option in the game for gpu buffer it says 'The number of frames the GPU is allowed to buffer' there is selection of 1-5 i have set it at 1 should i change that to 5
  33. Sorry, I have no idea what it does.
  34. Alright thank you, i will defo need to get that overheating thing sorted out though even when im not playing games the temp still seems to be around 70'C+ when i'm not even doing anything that excessively uses the cpu
