Games lagging

  1. Hi,
    Not sure this is the right place for this post.

    I have just built a PC out of spare parts for my kids to use. The problem is that when first I start playing cod world at war it starts off ok but after a while it slows down and gets very jerky. Also after that the next time I play it starts off jerky from the begging. I am using cod war as a test game as they like to play zombies.
    I have done the memory timings,disabled speedstep in bios, updated all drivers, defragged, and made sure no unessassary programs are running in the background. All temps are ok.

    The spec's:

    Pentium D 3.4ghz
    Asus P5Q SE2 m/b
    2gb DDR2 800mhz (corsair)
    Factory O/C Geforce 8800GTX 768mb
    80gb HHD sata 2
    600w PSU
    Windows XP x32

    I have used the cpu,ram and gfx card together in a P5N23-e sli plus m/b and it played everything.
    I first put this machine together using an older different m/b but that was lagging so I bought this new m/b and it still dose the same thing.

    Any idea's will be gratefully received.

    Two limiting factors could be the amount of RAM you have and the page file. See if you can add another gig or so of RAM and set a page file about about 2 gigabytes and you should see an improvement. Aside from that, I don't know what else to do.

    If you don't know how to set the page file, start > control panel > system > advanced tab > performance > and check the page file size. Enter in a new size in megabytes i.e. 2048, and restart. It's been a while since I worked with XP, but I'm fairly certain that was the process.

    Right click on My Computer > Properties > Advanced Tab > Performance Settings > Advanced, See the bottom box "Virtual Memory" and click Change. The paging file should be set to 1.5 multiplied by your amount of your RAM.
    So 2048 * 1.5 = 3072

    I know you said you updated drivers, but have you checked to see that your bios is up to date too?

    Try resetting cmos battery on motherboard?

    Manually setting the size of the page file might work, but I don't think that the paging file is the problem here. This is most likely a video driver problem. It might have not installed correctly the first time and even after you updated the problem still remained (it happens). Try uninstalling it from safe mode and install it again.

    If it doesn't work then try installing windows7 or reinstall xp.

    EDIT: after googleing a bit i found out that many people experience the same problem. I'll try to find a a solution.
    EDIT2: it seems the game has some memory leak problems. Not everybody has this problem. There is a patch for the game (v1.1), but it doesn't help much. Just try what i told you do. If now then you're out of luck. buying another 2gb of ram might help.

    Pentium(R) I've heard of not that I'm try to 'squeak' you does it have a code eg.SL94W at the bottom / lower edge as I remember reading some 478pin & LGA775 having latency problems with large single Ram sticks?
    Which then begs the question is this one 2Gb stick of RAM because the article I read said the firing order was where the problem "most defined itself" They were testing a game called "Conflict : Denied ops" needless to say I bought the game as they described it in more detail than the Rig they were writing up :D

    still lagging

    Ok first thanks for all the replies.
    I have tried all the idea's except the last one as i'm not sure what is meant? I have also been using ProcessExplorer to try and nail the problem. I'm not that sure of what i'm looking at there but there are no hardware interrupts as far as I can tell except when the game first starts I get 1.78 then it returns to 0.
    I have 2x1gb corsair CMX 1024 I cant see the memory timings but I think they were 5,5,5,12.
    Also I am only using ATA drives.
    Again thanks for the replies i've been bashing my head off a wall on this one.


    Edit: the cpu is a Pentium D 3.4ghz 945 LGA775 without taking it out I cant tell you anymore. But it ran cod waw with no problems in a P5n32-e sli plus. sadly that m/b is broken.

    Here is your family of CPU
    You've probably tried reducing the frame size eg. from 1280*1080 to 680*480 in the game (and what about the shading and fog/definitions)
    Here's a link to Asus for drivers in-case yours are old and scratchy
    And there are better ways to loose Brain Cells than banging your head on a harder object ~ try a nice Red instead :)

    I have tried the minimum settings but with the MSI geforce 8800GTX (F,O/C) running at core speed 610 and 768 ddr3 running at 2000 it did run every game I had including Modern warfare2 at full spec with no problems. I have reinstalled xp downloaded a fresh gfx driver in case something was lost when I burnt it to a cd. There seems to be no reason that games slow down. But they do? (bangs head off wall again!). I even tried the gfx card in my comp and it ran fine no problems. It's looking like I'm gonna have to start from scratch again.
    The cpu is definatly a Pentium D 3.4ghz 945 and has ran everthing with no problems before.

    Thx again for the replys and idea's keep em comming please.
