Random low fps spikes in game

Hello there, I have an Acer Aspire 7720z (awesome laptop), no modifications whatsoever and its fairly new. ive had it for coming on 3 months and about 5 days ago my games started to lag randomly. I would get 5 minutes of high FPS in whatever game, say Garrysmod or Half life 2 i get about 50-60 frames, Countestrike is about 60-70 Left 4 Dead i get 20-30 and so on.

anyway this lag spike lasts about a minute and i get another 5 minutes free from it. I get this pattern untill im sick playing the game with that pettern of annoying drops in performance or i do something to crash the game. i always find a way to crash every game in every level =/. so my normal good FPS goes down to the likes of 10 to about 3, it gets gradual and lets off. my fps counter i had on shows in hl2 its that 50-60 then a while in it suddenly goes to 10-5 then its unbearable for a while showing only 1-4 and suddenly lets off. in some other games it starts and never goes away. Now Ive updated all hardware drivers, virus checked it, scans, defragged the lot. no improvement.

  1. i have the exact same problem, have you found anyway to fix it yet?

    it really does ruin gameplay and many people seem to have this problem but no reason why!! :(
  2. Its the Intel(R) 965 express chipset you are having on board.... ditch that and get a better graphics card...
    max refresh rate you can get currently is only 60pfs.... 75fps and above.. then you be in action :)
  3. It's not a graphic issue, at least in my case. I can run old and new games with the same problem. 20 seconds of 100FPS then like 10 seconds of 4 fps.

    -It's not a temperature issue, 45°C looks fine.
    -Not a spec issue, I have the 9600GT with latest drivers, 4 Gigs of Ram and AMD 64X2 3.0Ghz
    -Not a background processes issue, nothing is consuming neither RAM or CPU.

    Actually, with the game running, the CPU Usage is around 30% and the Commit Charge around 400 / 5211 M
  4. This problem used to happen to me too. Really annoying. Like my Fps usually is 70-100 in Counter Strike and all of a sudden 5-15. But I did the following. Worked for me at least: One of my RAMs was probably damaged so I took it out, but still didnt resolve the problem, then I cleaned my CPU fan and everything in PC. I play with my computer open. I get 70-80 FPS no problem. Though I am getting another problem now and I would like some help, its similar to this one. But a bit less annoying. Instead of falling to 5-15 FPS it falls from 60-80 to 18+ FPS in like 15 milliseconds. Its still annoying. I belive its cuz I havent enough RAM. Im gonna test low graphical games and see if thats the problem. If it is im gonna buy 1 more 1GB RAM. IF it isnt I, will be saving money to buy a new PC. Thats it guys.

    Here are My specs:

    Video Card: Sapphire ATI Radeon x1650 512mb(Pretty good)
    Proccessor: Intel Pentium 4 3.0 GhZ(Pretty good too cuz of the Proccessor speed)
    RAM: 1 GB ram(Acceptable)
    Motherboard: ASUS P5PE-VM(Not very good)
    Cooler for CPU: Came with my Proccessor(Seems to work fine, CPU temp around 60)
    Cooler for GPU: Came with my Graphics Card(Not very good, I get around 70)
    HDD: 1 with 49GB(CRAP) and anotherone with 149GB(Good)

    I have these games:
    1. Counter Strike Source (60-100 FPS)
    2. Half Life 2 Franchise (30-70 FPS)
    3. Crysis (20-40 FPS)
    4. Burnout Paradise (IDK, around -30 FPS)
