  2. The reviews on your site is good, but better if you inform the details about the compatibility for Xp and the support given,most problem is the the specs quite few informative, for example some laptop only ship with vista, and some of them will decrease brightness with XP,i also wanted to know since i can't keep up with the recent laptop release, busy with my jobs and study=) thank, i will drop comments on your site later

  3. I can not download IDT High-Definition Audio CODEC Driver
    from this site

    Can anyone give me another link.

  4. I will update the link and check back tomorrow, i will upload it and give the link, i already try the link and everything went fine but may be there are other problems preventing you from download the file, anyway i hopr you will be patient and check back tomorrow, k

  5. I have problem to install windows xp pro -- blue screen of death!!

    Trying to find setting in BIOS to enable and disable some harddisk figure but can't find it, please help!!!!!

  6. Trying to install Windows Vista Business, when come to Completing Installation ...... Nothing moving for hours !!!! What is happening to this notebook??

    This is my first time using HP laptop and it gives so much headache !

  7. I think you do not have to change the BIOS, follow this steps:

    Install windows XP on Compaq Presario CQ40-324TU

    If you installing Windows Vista and nothing moving for hours, try to use other Installation DVD,I myself sometimes need to repeat the installation of Vista in Compaq CQ especially because the problems is like yours, nothing moving for hours, i Have a loyal costumer that whenever i format his laptop i need to put extra fan on his laptop because if i did not, the blue screen of death appear(windows XP. Hope this information helpful and inform your progress

  8. Thanks. I used another vista Home basic license dvd it worked.

    But it is just plan stupid that the laptop doesn't come with driver cd or dvd but a guide cd(for what??)!!

    I am using windows cp pro (license) version and it still give me "blue screen of death" Defiitely, need to reset BIOS but how? For ASUS laptop setup in BIOS fixed the problem but for this laptop I wonder how?

  9. i have post the method how to install windows XP(see my previous comment), you need to do some work before installing windows xp,

    "But it is just plan stupid that the laptop doesn't come with driver cd or dvd but a guide cd(for what??)!!"

    compaq CQ design for vista, not for XP, that what they didn't exactly tell you, but i don't know why seller nowadays don't remind every costumer the problems with XP. I will not go for compaq CQ if i want to use windows XP, i will go with Dell

  10. Good forum..But I'm having a problem while install sound device, once install a IDT sound driver, another high definition sound bus pop up and can't find driver. After reboot, my sound card driver lost already. Please help

  11. First i want to know the sound work or not, it seems that the driver here still not complete, i update soon but give me some time to make research for the appropriate sound driver, i will inform when i update the solution. thanks for your feedback

  12. Is work after installed the sound driver, after reboot, the sound driver is missing. Then you need to update UAA driver 1st then update WDM. Then the sound card works again.

  13. Do you mean every time yoou restart computer you need to do the same method to get the audio works?

  14. after installing all the drivers for vista I still can can't get touch pad working.

    Any driver for touch pad (using it without mouse)

  15. try this:

    suggested you install Microsoft .Netframework 2.0 first.

    also don't forget to install and update your laptop:

    Essential System Updates for Microsoft Windows Vista Service Pack 1 (SP1)

  16. Vista should have Microsoft .Netframework 2.0, right?

    I installed both and it is still not working :( I read somewhere saying needs to set in mouse properties. But can't find what mentioned.

    HP is so stingy in giving drivers cd :(

  17. You know what, the silly little rectangle button above touch pad being pressed making it not functioning :)

    Press that button and turn light from red to green it will activate the touch pad.

  18. lol, but i,m happy you solved it, it should help others too=)
