Haunting FPS drop issue. Please help me get past this.

Hey guys I've been having this problem for the past 6 months or so and I have little reason to believe it is hardware related. I've gone as far as changing my PSU and it's really driving me nuts. Whenever I play a game I would set the optimal settings for my pc specs. I'd get the respective fps range and randomly the fps would drop to 5-10 fps. The audio would stutter a bit or become laggy too. It wouldn't last very long and you would then get the normal fps which feels like a movie going back to normal speed after the play speed has been decreased.

Here are my specs:
  • MSI G41M-P33 combo
  • Q8400 stock(using a Deepcool Ice Blade Pro HSF)
  • 2 x 2gb ddr3 ram 1066mhz
  • Palit Jetstream GTX 670 2GB - currently using this
  • Gigabyte GTX 560 - used this before
  • Palit GTX 560 - used this before
  • 1 x 500GB SATAII HDD


My OS is Windows 7 Ultimate 64-bit. I used to be on Windows Vista 32-bit which I never had a problem with. I know I used Win7 64-bit before but I can't remember which build and I had a different mobo and processor then. I didn't have problems.

Through my exhausting effort to fix this, I've read that Windows 7 has an issue with onboard Realtek drivers. I did all the fixes regarding this and they didn't work. Only thing I haven't tried is getting a separate sound card.

Below is a list of fixes I've tried so far:
  • Clean out the fans of the video cards I've used excluding GTX 670 because that is a brand new one.
  • Bought another PSU. First one was a Corsair VS550 and the one I'm using now is a Modular Silverstone 700w PSU.
  • Reformatted then did a clean install. Same OS though, Win7 Ultimate 64-bit.
  • Underclocking my videocards.
  • Tried out different nvidia drivers.
  • Totally lowering all of my games' settings.
  • Switching to Basic Windows 7 theme from Aero.
  • Disabling indexing service.
  • Updating my Realtek driver to the latest one.
  • Uninstalled Nvidia HD audio driver and 3D stereoscopic.
  • Disabled Windows Media Player Network Sharing Service.


This is really frustrating. The only fix I'm thinking of next is going back to a 32-bit Windows 7 OS or a Windows Vista 64-bit. I'm also going to see if buying a sound card would to the trick. I appreciate your input and whoever will provide me with a solution, man I owe you my life! :)

    2. Defragment your hard drive.
    3. Scan your computer for viruses.
    4. Make sure that EVERYTHING is up-to-date (e.g. Windows, drivers).
    5. Make sure all of your computer components are installed properly (e.g. check of graphics card is missing a wire).
    6. Refresh your Experience Index.

    No problem! ;)
  4. After scourging the internet once again for solution, I think this may have something to do with the northbridge of my motherboard overheating.
  5. I've solved this already. Replaced the motherboard altogether and I have upgraded my q8400 to i5 2320. I'm currently using an Asrock H77 board which is quite decent.
