X58 Pro will not install Vista/7

Specs:
Mobo: MSI X58 Pro MS-7522
CPU: Core i7 920
RAM: Corsair TR3X3G1333C9 Triple-Channel DDR3 1.5v 9-9-9-24
PSU: Thermaltake PurePower 500W +12V-14A and +12V-15A
OS Installed: Vista Ultimate 32-bit
Primary HDD: Seagate 750GB 7200 RPM
Secondary HDD: Seagate 200GB 7200RPM
History: Original BIOS always gave me a delayed POST issue. Fan spins at full speed for 15 seconds before POST'ing. If running for 15+ hours, a restart will cause the fan to just spin at full speed and NEVER POST unless I turn the computer off, reset the mobo, wait about 20 minutes and then boot it and it will do the 15 second thing. I just got used to this and dealt with it.
Finally I updated the BIOS to 8.6 when it was the current version and that delayed POST problem was history! Then other things happened. "Host process sevice" would stop working and force a 1minute scheduled shutdown that I would have to terminate by typing 'shutdown /a' in the shell.
Recent events made me decide it was time to just wipe it and move on to Windows 7. I already have it on laptop (i'm on right now), so I'm using the same disc to put it on this desktop. I have tried a Retail Vista disc and this Retail Win7 disc and both of them yield the same result: I boot to CD, it loads the prep files and just when you think the installation program is going to begin, the monitor goes to standby and the computer just runs doing nothing. It simply keeps running without anything happening.
I went back into windows and wiped my alternate HDD and decided to try just installing the new OS to this alternate disc. I wiped it in Disk Management, turned off the computer, disconnected the primary HDD so that only the one I wish to interact with is available. Same result, install hangs just after prep
Assuming the only thing that's now possibly affectin gthis is either the BIOS or the RAM. I flashed the BIOS with the newest version, 8.8. Same result, I flashed again with 8.7; same result. I decided maybe I need to go back to what I had when I installed it the first time, so I flashed it with 8.1 which is just a tiny bit more recent. Guess what, the delayed POST with the full-speed fan issue came right back, but the install gave me same result. I'm usually pretty good about things like this, but I really can't figure out where to go from here> Someone please give me a little insight, I really appreciate it.

My Video card is an ATI Radeon X1900XT PCI-E card that I've never had issues with in the past.
I am running the 64-bit Win7 disc right now....fingers crossed....(only 1stick of RAM currently installed)......fail :(
EDIT:: OH MY GOODNES!!!!!!!!
Okay, so thank you for mentioning the video card because I would have continuted pulling my hair out. The fix? drumroll please.......The prep showed in one monitor but when the program actually got to the "install now" page it was sending it to the 2nd monitor which I only turn on when I'm doing web work.
Removed 2nd monitor from equation, rebooted and the install is running. Wow I feel so dumb right now.

  • Acrobat 9 Pro will NOT install (CS4 Design Premium)

    Acrobat 9 Pro will NOT install (CS4 Design Premium)
    Acrobat Pro 9 will not install (FAILED), although every other program on the CS4 DVDs did install properly.
    I have followed the instructions, and have tried with no programs running, not even virus protection (which is an insane thing for Adobe to demand of a product being installed where the installation routine is expecting an Internet connection): FAILED.
    I uninstalled my Acrobat 6 Pro, (a standalone Pro version that I had to have  a few years ago.) I uninstalled that working program knowing I had no idea where my original Adobe Acrobat CD is located, so I was essentially cutting myself off of Acrobat Pro if the Acrobat 9 Pro install continued to fail.
    I reported this to Adobe support online.
    I have followed the instructions to disable startup items and services, then tried the Acrobat 9 Pro install: FAILED.
    At that point, I gave up installing Acrobat 9 Pro. I didn't have any more time to screw with it - I would re-visit the installation failure later.
    Lo and behold, a client sent me a PDF file of a brochure, in an email, and I had to grab some text from it to put on his website (Done in Dreamweaver CS4.) Well, damn, now I'll have to go back and get that install to work...FAILED!
    Suspecting a problem in the installation routine on the DVD, I decided to download the trial version of Acrobat 9 Pro. So, I did. It downloaded and installed without a hiccup, and I had Acrobat 9 Pro working for 30 days...
    I did what I had to do, using the trial version, then figured I would re-visit the installation issue later, when I had a few hours to dedicate to all the hell of calling Adobe software support, handholding, maybe registry edits, multiple reboots, and multiple attempts at doing everything again, just so the support person would know that I did follow all the steps correctly to prove thw outcome is sill FAILED!
    Oh crap, I got another PDF file. No problem, I thought, I don't need to edit the PDF, just read it. When I tried to open the file, Acrobat 9 Pro plastered a screen over the program - the screen saying my 30 day trial version has now run out, demanded a serial number, or quit. My CS4 serial number would not activate it, and so I had to quit, not even being able to read the PDF file.
    So, I un-installed the trial version of Acrobat 9 Pro that had installed without a hitch and had worked flawlessly for 30 days.
    Now I'm going to have to visit hell, and get the software that I paid hundreds of dollars for to work...
    Please STOP and NOTE: Acrobat 9 Pro installed perfectly from the downloaded Internet version. What does that tell you? There are no operating system issues, no hardware compatibility issues  (which I knew anyway, as the OS and hardware is up to date.) Even more significantly, there is no issue with the Windows registry, or other versions of Adobe Acrobat that had been installed before in the machine. My conclusion was that it has to be a problem with the installation routine on the CS4 disks.
    So, I spent an hour on the phone with Adobe personnel: software support, to customer service, to sales, to customer service, and back to sales. After software support came to the conclusion that I needed to UNINSTALL ALL OF CS4, and run a clean-up utility, I knew I had to try getting a new set of DVDs and hope the installation routine problems/bugs had been worked out.
    After being batted back and forth by Adobe Customer Service and Adobe Sales, I finally got someone to agree to send a set of DVDs to me.
    I got the DVDs. I tried to install Adobe Acrobat 9 Pro: FAILED
    As I told the software support person, I do not want to un-install the entire CS4 suite. I have all of those programs working fine, and have about a dozen web sites within Dreamweaver CS4 painstakingly set up and active, and some of them are current projects that I am working on daily. I also have multiple extensions installed, and spent quite a bit of time getting all of those programs set up for my preferences and my work flow. I DO NOT WANT to uninstall the entire suite of applications to get Acrobat 9 Pro to install.
    And the conclusion of the "sophisticated" Adobe Support Advisor as to what specifically was the instalation issue?
    Adobe Support Advisor
    The module found no solutions to report for the selected log file.
    If you continue to have difficulties with the application,
    please contact Adobe Support: http://www.adobe.com/support
    System Information :
    Operating System = Windows XP
    Locale = en
    At this point, what I want is to know what registry keys to edit and which folder(s) to delete to eliminate previous traces of Acrobat. In other words, just exactly the tiny piece of the "clean-up utility" that I need to run in order to allow the *Y#^%@#&#(& installation routine to work for Acrobat 9 Pro. I have no intention of uninstalling Dreamweaver CS4, as that is my business livlihood, and I know that my Dreamweaver CS4 client files/sites could not be read by earlier Dreamweaver versions. Asking me to uninstall Dreamweaver, Photoshop, Illustrator, Flash, InDesign, and Fireworks is insane. Your bad installation routine is not my fault, and you cannot expect me spend countless hours getting all those programs set up the way I want and with all my client/work files working correctly and all the extensions set up properly. So, if Adobe software support refuses to tell me what registry keys need to be changed, then I want Adobe Sales to send me a new, standalone version of Acrobat 9 Pro on disk.

    I hit the same problem except I had a Reader X installed not a pro version.  For me the solution was to really make sure that nothing else was running.  I followed the steps from http://support.microsoft.com/kb/2438651#reso2 the link is goofy so here is the pertinent text:
    Programs that are currently running on your computer may be interfering with the installation processDisable programs that might be interfering with the installation process. To do this, follow these steps:

    , type msconfig in the Search box, and then click msconfig.exe.
    If you are prompted for an administrator password or confirmation, type the password, or provide confirmation.
    On the General tab, click Selective startup, and then click to clear the Load startup items check box.
    Click Services, click Hide all Microsoft services, and then click Disable all.
    Click OK, and then click Restart.
    Try running your software program installation.
    When you are finished troubleshooting the problem, restart the computer in Normal Startup mode. To do this, follow these steps:

  • Mid 2010 Mac Pro will not install 10.7.3 update

    Hi all,
    My Mac Pro (Mid 2010) will not install the 10.7.3 combo update. I use the software update tool to download the update, it goes to reboot. It starts loading the update in and at the very end it will tell me none of the updates can be installed because an unknown error has occurred. I have tried multiple times and had the same result.  It also will not install any other updates such as the Airport Utility and iTunes update.  This is a work computer so I think it is important to have all the updates installed on it.

    Then the problem is:
    You have Apple Pro RAID controller
    A software RAID
    Lion Recovery should be on one of your hard drives, not RAID.
    Do a clean install of Lion on one of the other hard drives you have
    Anything else we should know about your setup? controllers do matter.

  • Acrobat Pro will not install

    Okay, excuse my lack of patience. But I have now called Adobe customer servic (in India, and I'm in the U.S.) three times now, and I have not resolved this issue! I am a Creative Cloud member, and my Adobe Acrobat Pro will NOT work. On top of that, the Adobe Application Manger is $%@ useless. I get errors constantly. I'm on Mac OS 10.8.1. My other Adobe software works. But Acrobat Pro has not worked at all since I purchase Creative Cloud a few months ago. At any point, if Adobe would like to fix this issue, that would be great. Like I said, I've already called three times in the last two months. And the low level tech support guys are useless. I spend an hour or two on the phone with them and the issue is NOT resolved.

    So, it totally appears as if it was a network issue. The corporate network where I work is quite likely the culprit. Where I was thrown off is that since I have admin rights on my computer, I can install software. But using Adobe Application Manager to install Adobe software wasn't working. And to make matters worse, there didn't appear to be any way to install Acrobat Pro for Mac without using AAM. The workaround that I used previously was to install the trial versions of Adobe software, and then just register them using my username and password. But the workaround for being able to install everything using AAM was to bring my computer home and download from my home network. Unfortunately, Adobe tech support didn't suggest this during the three times that I called them. But it doesn't matter now, problem is resolved.

  • Itunes 7 - win xp pro will not install "iTunes needs quicktime" error

    iTunes 7 will not complete the install - it says the old version of iTunes could not be uninstalled and then says "iTunes needs quicktime". I tried installing quicktime alone and it also won't install saying it cannot remove the old version. Tried a manual uninstall and I get the same error.

    A tip posted by b noir on the following link solved my problem. I just downloaded "Windows Installer CleanUp Utility" from Microsoft, removed my existing version of Qiucktime. Restarted my computer then started fresh with Itune 7 installation. No more problems.

  • MacBook Pro will not install iPhoto

    My new macbook pro would not let me update my iPhoto application. So, I was told to try to delete it then reinstall it. The apple tech I emailed with told me this was because I needed to download the iOS x lion software so I did and it will not let me reinstall my iPhoto back to my computer. When I try doing so, it asks for my apple ID and password, I enter it, then a message appears that says, "These apps cannot be accepted on this computer. Future updates of these apps can be found through Software Update." What do I do to get my iPhoto back!

    Contact the apple tech you worked with and have him resolve the issue for you.

  • My MacBook Pro will not install yosemite

    MMy installation will not work at all it sits at 22 minutes remaining then cuts out and pops a message saying 'file system verify or repair Failed' then I try to to verify disk to repair it but it says I have to repair it first! Help I can't use my MacBook!

    Since it sounds like after you did the install it worked good for you, but after using migration assistant you ran into problems . I would have to say that something in you older files is causing a problem. Try booting in safe mode.http://support.apple.com/en-us/HT201262  Then is this works go to your system preferences /users/login items and uncheck any that are there. Then go to security and uncheck require password. You might have to unlock and inter password to do this. Then go to utilities/console/crash report and see if you can port it in here.  See if you can now boot normally.

  • X58 Pro will not power on

    CPU: Intel Core i7 920
    Motherboard: MSI X58 Pro LGA 1366
    Memory: OCZ 6 GB (3 x 2 GB) 240-pin DDR3 13333 (PC3 10666) SDRAM
    Video Card: nVidia 9800 GTX+ 512 MB
    PSU: Rosewill RP600V2-S-SL-S 600W
    I just received all my parts today and I set everything up. I'm fairly certain that I put every power cord in the right spot. I have the CPU, heatsink and fan, three RAM modules, video card, two SATA hard drives, one SATA DVD drive, and the PSU hooked up. The LED power light on the motherboard lights up, but when i press it, nothing happens. When I press the on button on my case, nothing happens either. The fans don't start, it doesn't post - it seems completely dead.
    Does this seem more like a motherboard problem, or a power supply problem? Maybe one of them was dead on arrival? Thanks in advance for you help!

    Tried what you suggested - nothing.
    Minus the lone green LED light on the power button on the board itself, there really is no other indication that there is any electricity. Yes, there is a power button on my power supply, and it's turned on. I can tell when the power's on, because when i have it unplugged, the LED light goes off. It's just weird that electricity is getting to the light, but no other part of the motherboard...
    If i did connect something wrong, which is possible, do you have any suggestions of what it might be? My power supply has a 20 + 4 pin cable, and i connected the 4-pin on pins 12-24 (closer to the top of the motherboard) and the 20-pin closer to the SATA connectors. That's what the directions said to do. Other than that, I connected two 4-pin cables right to the left of the CPU, in order to power the CPU. Those are the only power cables that connect directly from the PSU to the motherboard.

    I hope you don't mind me asking this question for Jack the Newbie.
    You say i have to use a Windows XP-Pro Install-CD that includes SP2 as well as the JMicron driver for the JMicron IDE-Port which i have my Optical Drive connected to.I know this is telling me how to fix my problem, but what i would also like to know is WHY do i have to install it with SP2 & the JMicron driver like this on my P965 when it installed on my old pc with just the XP-Pro Install-CD.
    Your Windows Installation CD should be as up to date as possible, especially for newer hardware.  SP1 is from 2002, SP2 was released in 2004. Neither SP1 nor SP2 install CDs provide the proper drivers for the JMicron chipset used on your mainboard.  I cannot give a detailed list about the differences between SP1 and SP2. I just know, that there are a lot of problems when people do not use SP2 on Intel 975/965 Chipset-boards which where released in 2006. 
    When you say that your installation works fine on your old PC I believe you.  It worked on my old Laptop too.  However I was not able to install XP Pro on my 975X-board without SP2 at all until I upgraded my Installation CD.

    Garfield,
    I had exactly the same problem--because I had my optical drive hooked up to a Promise IDE controller, rather than to a mobo IDE connection.  Turns out the Promise will read and write the optical drives OK, just won't boot from them properly.  And, somehow, that affects Windows Setup.
    I don't know anything about the JMicron and the need for SP2.  But, as you can see from my sig, I'm using XP Pro SP1, and once I moved my NEC 3500 back to the mobo IDE (as secondary behind my IDE hard disk) everything worked like a champ.
    Just my $.02.

    To relate Garfields problem with your solution is a mistake.  Your board does not use any JMicron hardware, has NVidia chipset instead of Intel and an AMD CPU.  Your are talking about a totally different Setup here.

  • Windows 7 Pro will not install on iMac after HD replacement.

    I have a late 2009 iMac on which I have OS X 10.8 Mountain Lion and ran Windows 7 Professional in Bootcamp. My iMac wound up having a defective hard drive which was just replaced last week under warranty. The problem is now I am unable to install Windows 7 in Bootcamp. I use the Bootcamp assist to partition the HD, it goes through the motions of installing Windoes 7 but at a certain point after 2 reboots and just before it would say Windows is setting up your computer for first use the screen goes black and nothing happens. The iMac is still turned on because if I hold the power button down I hear it shut off. When I turn it back on I can see that Windows was not fully installed.I tried to see what it says running in safe mode, and then I can see that it wants to continue setting Windows up but I get a message that Windows cannot be installed in Safe Mode, and I should reboot but then I get the black screen again. I've tried to repair the installation but to no avail. I've done this using both 32 bit and 64 bit with full disc of Windows 7 Professional but neither work.
    Does anyone have any idea what could be wrong and what I can do to rectify this problem? Thanks in advance for any help.

  • My Macbook Pro will not install/restart for updates when I use Software Update

    So when I go into System Preferences and go to Software Update, I click the Check Now Button. It looks for available updates, and gives me a box that says "Software updates for your computer are ready to be installed. Do you want to install them now?" with options to "Show Details", "Not Now", and "Install and Restart". However, when I hit the install and restart button, after hitting a few confirmations, the app simply logs me out, but doesn't restart the computer. When I restart the computer from the Log In screen, the computer reboots without installing any of the updates. I'm on Snow Leopard, is that why updates aren't installing? Am I going to have to manually download all of the updates, or at least that updates that are compatible with Snow Leopard?

    There are no updates for Snow Leopard except to Mountain Lion.
    Upgrading to Snow Leopard, Lion, or Mountain Lion
    You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
    Upgrading to Snow Leopard
    You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
         Snow Leopard General Requirements
           1. Mac computer with an Intel processor
           2. 1GB of memory
           3. 5GB of available disk space
           4. DVD drive for installation
           5. Some features require a compatible Internet service provider;
               fees may apply.
           6. Some features require Apple’s MobileMe service; fees and
               terms apply.
    Upgrading to Lion
    If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
    You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax.  It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
         Lion System Requirements
           1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
               or Xeon processor
           2. 2GB of memory
           3. OS X v10.6.6 or later (v10.6.8 recommended)
           4. 7GB of available space
           5. Some features require an Apple ID; terms apply.
    Upgrading to Mountain Lion
    To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
         OS X Mountain Lion - System Requirements
           Macs that can be upgraded to OS X Mountain Lion
             1. iMac (Mid 2007 or newer)
             2. MacBook (Late 2008 Aluminum, or Early 2009 or newer)
             3. MacBook Pro (Mid/Late 2007 or newer)
             4. MacBook Air (Late 2008 or newer)
