Windows 7: Windows 7 Pro x64 hangs during startup even after fresh install

SOLVED-Windows 7 Pro x64 hangs during startup even after fresh install

Hello, I'm having a problem with a computer that I've had for a while now. It's a custom build that's several years old, but I have recently changed out the CPU and fan, video card, and hard drive all within the last year. The operating system, Windows 7 Professional x64, was installed by me almost 2 years ago. It has been running fine this whole time, through all the hardware replacements, until yesterday when I shut it down, left the house, came back and the system froze on startup. After several restarts in which it froze in exactly the same place, during the logo, seemingly just before it goes in to load the desktop, I ran memory and hard drive tests using my Windows installation disk, and also an Ubuntu Linux DVD. Both came back without problems. I tried partitioning a section of the hard drive and doing a clean install, but after installation it rebooted and had the exact same problem. I'm thinking it could be memory related, whether its a bios setting or maybe a bad stick, but I'd like to get some input before I go any further. My system specs are listed in detail on my profile.

Load bios defaults and run memtest for some loops.

First thing I'd try if it were mine would be a safe mode boot to, possibly, determine software or hardware fault.

Sorry it seems I left those out, safe mode hangs during driver loading, and I have loaded the bios defaults with no avail. And after installing Windows on the seperate partition I made sure to take the disk out after the first reboot. I have even installed Ubuntu Linux and couldn't boot into the desktop, it kept bringing me to a command promt login, even tho I specified in the installation setup to log in automatically, and besides it should go to a login screen not a command promt. Remember the system ran beautifully until yesterday. I should also mention I'm typing all this on an Ubuntu LiveCD booted on this system.

Ok, so this still has me really confused, ive completely wiped my hard drive, I now have Windows 7 dual booting with Ubuntu Linux, and I can run Linux perfectly whereas Windows still hangs during that loading screen.

do you have a ide cd or hard drive ? I had the same issue -when I disconnected the ide cd drive and no pause , when I reconnect the ide cd drive , 40 sec pause ..

GRUB can corrupt Windows 7 when on the same HD. Best to use separate HD's booted via the BIOS, not GRUB.

How many times did you run Startup Repair on Windows 7 from the booted Windows 7 DVD Repair console or Repair CD? Startup Repair - Run 3 Separate Times Using multiple tests and fixes, it can sort out causes of such problems but may need to be run repeatedly.

Test your HD using maker's diag/repair full CD scan: http://www.carrona.org/hddiag.html

It has the same issue even with windows installed by itself. The only reason I have Linux on here now is because Windows stopped working. I've ran startup repair a few times, it doesn't help.

Did you wipe the HD with zeroes before reinstalling Windows 7 by itself? GRUB corruption remains if not.

We need to rule out GRUB corruption before proceeding to troubleshoot why Windows 7 hangs at startup whereas Linux doesn't.

Tips for getting a purrfect reinstall based on hundreds done here: re-install windows 7

i dont believe its anything to do with grub corruption because ive never had linux installed on this hard drive until recently, because of this freezing problem. it ran with windows installed by itself for almost 2 years and then out of nowhere just started freezing during the loading screen. i then did a fresh install and it still froze. now i have linux installed just to have something to use but windows still freezes and i havent found a way out of it yet.
