[SOLVED] Windows 7 32-bit installs but 64-bit stalls

My system was running 32-bit Vista and I tried to update to 64-bit Windows 7. It would hang once it got to the starting windows screen. Control-alt-delete wouldn't launch task manager and I would have to use the power button to power off.

I tried repairing the installation but it says that it can't automatically fix the problem.

I did the memory test and it passed.

Reading at other places I have tried
* changing the boot order from HDD/DVD to DVD/HDD.
* ejecting the DVD and closing it while it was hung
* disabled the USB Keyboard and mouse in BIOS
* waited 30 mins
*disabled the USB controller in BIOS
* disabled the FDD and LAN in BIOS

nothing worked.

So I tried installing the 32-bit Windows 7 and it worked with no issues.

What would you try next to get the 64-bit version installed?

Thanks very much in advance.

what are your ur computer specs???

Enable Plug & Play OS to yes or enabled, if that setting exists in the bios.

Do as LeHam asked and post your computer specs. Motherboard model and brand, RAM, etc. as that will help immensely.

Nearly all recent motherboards of the last two years are "plug & play" so the previous reply may or may not help. Plug & Play was a setting for older motherboards.

You can't do a upgrade of 32 bit Vista to 64 bit 7. You need to backup what files you want to be in 7 and disconnect your internet cable from the back of the pc. Set the bios to boot from DVD drive by hitting Del key when you turn the pc on. Select to Boot from DVD by pressing Enter key. Click Install now, Click Advanced Options, Format your C: drive install Windows 7. After install is complete rehook your internet cable in Windows 7 and open and close DVD drive click on the UAC Prrompt to let it run yhe DVD and do an Upgrade Install. After the Upgrade install is compltet Activate Windows 7 by right clicking Computer on right side of Start Menu and clicking on Activate Now.

You can do a clean or custom install too. Follow this handy little tutorial from Paul Thurrott's Supersite for Windows:
Clean Install Windows 7 with Upgrade Media

It is an Acer Desktop with an AMD Athlon 64 x2 dual core 4400+ 2.3 Ghz
4 GB ram

I ran the Upgrade Advisor and everything checked out.

I was doing a custom upgrade.

You have to do a Clean Install going from Windows x86 to Windows x64. You can use the Upgrade version, just follow my instructions from earlier. The first install Don't enter a Product Key and Uncheck Activate Windows when online. On the 2nd install from inside of Windows 7 select Upgrade install, enter the Product Key and leave the Activate Windows when online checked this time. After the upgrade install completes right click on Compputer and click on Activate Windows now. After that get all Windows Updates. You'll probably have to run that a few times until it doesn't find any. Then update your drivers from either Windows Update or the various manufacturers of your computers components. If you get any BSOD's I'm sure TorrentG will be glad to help you solve them.

brkkab123 is correct. You cannot do an upgrade from 32 bit to 64 bit. You have to do a clean or custom install.

Check out Nibiru2012's link above for a tutorial.

DON'T DO THE UPGRADE INSTALL! You're just wasting time and it doesn't really work that great anyway.

Do a clean / custom install.

I have personally used Paul Thurrott's method many times on clients and friends computers and it works flawlessly! Believe me this one time.

I don't claim to be a "know it all" but I do know the Paul Thurrott method works!
