  20. need help!!
    may i know the procedure to format the compaq CQ40-401AU by using XP driver? i had burned a XP driver disc, and download all the driver installation software from the link given.. isit all the procedure to format is same as normal laptop example boost the XP driver disc and then format the partition and install the WXP. after that install all the drivers? Thanks very much for your kindly information.

  21. You must create a new win xp CD from your original it called slipstream process. You must format it with a new cd which you need to create, read here for the guide:

    after finish creating the cd,insert the cd and format it normally.

  22. Thank's a lot black-x. My laptop is running well and all my drivers are working except my microphone near my webcame. in my device manager said my "sm bus controller not installed". i didn't update my bios because my bios version is F.42 is up then F.22 or the others in the web. is it make any problem ? but my audio is working well without microphone function.
    should i downgrade my bios version ? which version i must use ?

  23. That bios is for Compaq Presario CQ40-104AX Notebook PC with Vista. Is it compatible with cq40-401au with XP ? There are 3 versions :
    F.22,F21,F.03. Which one is compatible with my cq40-401 ?

    thank's for your help.

  24. I suggest that u avoid bios upgrade and downgrade, because it can cause system failure (your laptop will freez and running very slow)and i suggest use the default BIOS. Before i suggest any software or driver, did you check at the volume manager (double click the sound icon on the taskbar or right click and select open volum manager), click options and select propertise, mark all of the list given then click ok, then make sure the microphone volume in not mute. Inform back the progress

  25. Thanks very much again. I have already checked my microphone is mute. And it is working now after i disable its mute. And how about the sm bus controller driver ? is it chipset driver for amd ?

  26. this file is corrupt :
    "High-Definition Audio (HDA) Modem Installer and Driver"

    and i cant open "Realtek RTL8102E Family PCI-E Fast Ethernet NIC"

  28. mr_fatcher i dont really know about the sm bus driver (controller) but i think it is not essential and you can use your laptop normally without update those driver,check back one week from now i will update the smbus driver.

  29. My problem is solved now. my sm bus controller is detected now by using your ATI Catalyst Driver for Motherboard edition. I had used ATI Catalyst Driver but not for motherboard edition. I have changed it now and it's working excellent.

    need some advice pls...

  48. here are some suggestion for your bluetooth driver:
    you also may try to install your original bluetooth vista driver

    I must use headset to hear the sound..

    I do not know is it driver problem or hardware problem?

    Please help

    thanks before..

  50. hi jollysols, first i hope your model is CQ40-401au or CQ40 model, if u are using this model the driver id gave will solve your problem, you may reinstall again the sound, second, you have the small speaker icon at your taskbar near to the clock, double click or right click select propertise, there make sure the setting is right, if there any panel mute, uncheck the box, for now thats the solutions i can suggest, it may cause from the hardware itself, if you dont want to replace the speaker(internal) you may buy the speaker that ppl use for desktop, any updates report back,

  56. greetings
    i just bought my new compaq laptop which type is CQ40-416AU. But it came up with Wndows7 OS and i have no idea how to work with. I prefer XP SP2 just like my Acer. And those driver links... so confusing :(

    Can you send me all driver links for my CQ40-416AU to my email?

    thank you in advance

  57. i'm using compaq cq40 401au... but, when i try to format from vista to xp sp3, an error occur when the boot want to enter windows setup.. please mr blackx.. help me..

  58. you cant format and install xp directly by using the windows XP cd, you need to create a new windows XP cd using the one you have now. Follow this guide here:

  59. I can install automatically 7 unknown devices by connect the internet. Unknown devices --> right click --> update driver --> next --> next

    thank for links.

  60. Sir, pls help me wd my problem.. i really cant figure out how to install win xp on my compaq presario cq40-416au..ive tried the instructions u have given, still no luck..please email me the full details step by step process. please mr black, hope you could grant my simple request..thanks hers my mail

  61. Hi Dhenz,
    check your yahoo inbox =)

  62. thanks for the quick response..ive followed everything, the instructions the steps and yet still no luck.I got a err message of: The file ahcix64.sys could not be found Press any key to continue.. what should be the problem mr black..thanks and more power.

  63. I'd change the instructions, check back the method in step 8

  64. Ive already done it sir but still no luck..ive also tried to load the x64 only and its looking for the x86 so ive tried both to load and it would prompt me that ahcix64.sys is corrupted...huhuhu..i need this to be in XP badly. please, is there anything else i could do..thanks

  65. yup, check ur email, normally x64 is corrupt cause by use the same folder to repeat slipstream. If you were to repeat the p[rocess delete the old file and folder, create new one.

  66. mr black sorry for late post..i was asleep..and it turns out ur tips works..i did wat u said earlier and viola! i installed d win xp, now i hav to work with the drivers post bak for progress..thanks so much to you sir and more power..salamat!

    yes normally for CQ AMD model use same drivers but use the drivers from the link i gave because the version is newer and updated. =)
    report back the progress

  69. Dude, I have to comment.

    I was attacked by a malicious virus about a month back. Then, I reinstalled Windows XP SP3.

    I wanna thank you for providing me the drivers and necessary softwares for this CQ40-401AU; seriously, if you had not done this, I would have no computer to work with.

    Again, I thank you for your amazing work. My gratitude, good sir.

  70. Please help! How do I fix this! my laptop user account failed to load. this is what appears on the screen everytime I entered my password: The User profile Service failed the log on. User Profile can't be loaded...Please help, I need to access my USER account.I currently use the guest acct for an access. thank u very much!

  71. Ok, first try system restore,

    1. Restart, press F8 repetedly.
    2. when options appear, select safe mode,
    3. Wait until log on screen appear, the select administrator
    4. Log in, click start, all programs, accecories, system tools and select system restore.
    5. select restore my computer to erlier time.

  72. for Black X:thank u for the advise! (Re:USER Profile Service can not be loaded

    I brought my unit to the store where i bought it..the attendant tried the same option as you have advised me earlier. We can't find the restore point when opening the safety protection..worst, he was trying to figure out how to fix it until he came to removing the password of the admin acct, which was I guess was never the problem. bottomline, he made the problem worst, he removed password, he made new password, and I guess forgot it..worst, when restarting again and accessing the admin acct, password incorrect appears..can no longer access the safe mode. what do I do with it! I don't want to have it reformatted (if I still have other options), coz I got to lose lots of impt files..Pls. Help! Big Thanks!

  73. ok some info ans option that might help you.
    First when u log in to safe mode, you can create new ADMIN account, and after restart and log in to new admin account, you can remove the old admin account (the one that you forgot the password). System restore is one of the solution which normally works.

    ok now several option you can do which i always do to recover file.

    1. Installing windows without reformating it:
    if you perform this (if you know how to format make sure when the screen appear ask you to format it or leave current system, choose leave current system) It will install new windows XP and when restart you will have 2 windows to choose, the old one and the new one. So you files are not wipe out and you still can access it.

    2. Another faster without installing windows XP is to get a bootable UBUNTU CD, you can run it without having to install it and you can recover all your files (transfer it into another partition or pendriver before format it.

    3. My favourite is installing windows 7 b(also without format it), this similar to XP (no 1) but the installation process are far easier.

    There are maybe way to reset it, ill keep you update and do some study about this.

  74. How to change the memory controller from ACHI to IDE for HP Compaq Presario CQ40-401au because when i install Windows XP sp2 the blue screen appears because the Memory Controller Doesn't Support..

  75. For CQ40-401,
    The option to change IDE to ahci only for certain laptop especially acer, CA40-401 doesn't have that option, but to install windows XP in CQ40 model you need to follow this guide:

    a little info, when your laptop cant install XP, first cj=heck at BIOS for the setting to change IDE to AHCI, but of there no such option, you have to perform slipstream like the link i gave above. For now i confirmed that CQ40 doesn't have option to change IDE to AHCI, and you need to perform slipstream.

  83. Hallo black-xx
    I have posted the question on your block about bios problems on cq40-402au and ask you to give step by step to replace the bios. until now still no answer from you. or you did not know?

  84. i think i already reply it but maybe i miss your comment

    here is the BIOS file for your model:

    (p/s: i suggest use the f.33a version.)

    Download and extarct the file using WINRAR. inside the folder you will see a file name 30FBF33.FD, change it to 30FB.BIN then follow instruction here

    i suggest you do head reset first beforore flashing BIOS.

    1.Disconnect all peripheral devices and remove all USB devices and media cards. You want to test the computer not the accessories!
    2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds .
    3. Reconnect the AC power adapter (but do not connect the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a disk drive and fan turning.
