Weird Computer Lag Problem

I bought a Alienware m15x not to long ago, I installed a few games (Starcraft 2, TF2). Every thing was working fine until I bought CoD4 from Steam. CoD4 had a really bad frame rate lag problem, but i noticed it was also affecting Starcraft 2. I have re installed CoD4 a few times and it has changed nothing. Starcraft will run fine some days were I will get 60+ fps but other days i will get 12 fps. This only started to happen after i had bought CoD4 from Steam. I have no clue why this would happen and i could use some help.

  1. Try a virus scan.
  2. Yeah, I've done that. I did a full AVG scan and it came up clean.
  3. Have you tried uninstalling COD or has it nearly filled your hard drive.
  4. Check if you're GPU is overheating. Does the dip in FPS happen with all games ?
  5. you need to clean registry when you uninstall something,

    you wouldnt leave the burnt on crud at the bottem of a pot after making stew then leaving it there till you make the next one, would you?

    ccleaner is one of the easysit to use, might as well install and run smart defrag 2 while your at it as well, this will speed your computer up

    yeah the fps drop happens in all games, how can i see if it is over heating?
  9. Download HWMonitor

    Ok, so I downloaded it but how do I know if its over heating? What temperatures are too high?
  11. Tell us what Graphics card and we can give you a specific answer.

    I'd say 80 degrees C is when alarm bells should start ringing, but some systems run higher than that.
  12. Either what Nihilis told you
    Or just take a screenshot and upload it.
    Otherwise, just check the temps and type it here.

    @Nihilis
    Where were you the past month ? :)

    Ahhh, I was only here on a pseudo "holiday" while in France :( I still pop back every now and again (like now), but unfortunately time waits for no one, and I never have enough to carry on like I did back then.

    I'll try to make sure I'm around as much as possible though so I can continue being an accomplice ;P

    Nice to see you all again though folks :)

    the moment you start playing a game, it can overheat. You could leave it off for a month, and it would still happen if overheating was the case
