Windows 7: Windows 7 hangs at Start logo

30 Jun 2013   #1

Windows 7 Ultimate 64 bit
Windows 7 hangs at Start logo

Hello All,
Wow I have been at this for two days. Initially began when I installed an update. It was a Security update and I have no way of finding out what exactly. A program wouldn't load so I restarted computer and it hung at Starting logo.
I tried repair numerous times to no avail-windows cannot repair. I tried reverting to previous state before update or new software installed or whatever that option is called. It would hang.
I did a memory check and that is good. Re-seated memory as well
I turned off power and re-sat all of my cables.
I returned my bios to default settings. I had system overclocked so I thought this might help.
I pulled c: drive from computer and ran windows disk check from another computer. Windows and Crystal disk both said it was ok.
I ran a power test on the power supply and it is fine.
I wiped the c drive. I ran custom install of Windows 7 ultimate 64bit from my disk. I have done this many times before with no issues. The install worked first time I was able to get into windows. Windows stated it had to restart to finish something and guess what HANGS AGAIN.
I thought maybe my disk was overused so I burned and new one from ISO. I have LEGIT KEY.I ran it it loads temporay files and now hangs a Start logo for install. Lol.
I do not have a backup for this computer I just put together 3 months ago. I know, I know.
PLease help me with any advice.
Thank you for your time,

Win7 Ultimate X64

Generally when problem persists after reinstall i would suspect hardware issue in particular RAM
I would try running memtest to give RAM a thorough check or try booting on individual sticks

Test also your HD using the HD maker's Hard Drive Diagnostic Procedure extended CD scan, followed by Disk Check if necessary run from the Win7 installer's System Recovery Options Command Prompt.

If the hardware checks out then follow these steps:

Unplug all other HD's and peripherals,

Boot into BIOS setup, reset to defaults, save changes. (If an EFI BIOS you'll need to decide if you want UEFI BIOS vs. Legacy BIOS. If UEFI follow these special steps for Install, otherwise enable Legacy BIOS or Compatibility Support Module to proceed with normal install.) Set DVD drive first to boot, HD second, set SATA controller to AHCI, Save changes and Exit.

Then boot into Windows 7 installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here.

At first installer screen Press Shift + F10, or enter System Recovery Options to open a Command Box, type:

SELECT DISK 0 (after confirming Windows 7 target HD #)

Next click Install Now, then Custom install to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt. You are creating the partition here for the purpose of wiping the HD and marking Active which overcomes certain install failures.

Windows 7 Ultimate 64 bit
Update: Problem SOLVED!

I don't know if I am more excited about my system running better than ever or the wealth of knowledge I gained from this experience.
Your suggestions and steps were detailed and explanatory. I learned 15+ and executed successfully 10-only needed to do ten for the time being.
I can't thank you enough.

I decided to run in UEFI mode. Considering my motherboard was geared towards this, probably a great idea.
Windows UEFI. I looked up and/or implemented all of the options in the two posts.

Concerning the ASUS m5a99fx pro rev.2 Motherboard specifically.
In the UEFI Bios Utility(the BIOS):
1) I set to optimized defaults
2) Set Boot priority to 1-UEFI Optical drive 2-UEFI SSD for installation
3) Under Advanced Mode(defaults to EZ mode)>Advanced Settings> Boot>CSM=Enabled(it fills out rest for you)
a)I first tried to do disabled=UEFI only and saved but it would not save so CSM
b)CSM=Compatibility support Module:"for better compatibility, enable CSM to fully support the non-UEFI driver, add-on devices or the Windows UEFI mode"

I then began the process step by step in post. Install went without a hitch. My computer seems snappier but only time will tell.
I am currently working on SSD from options in post. Samsung Magician offers a lot of options and suggestions I need to look up before I execute. I do not want to hurt my performance.
Thank you both again for your time.
Time to back-up, optimize and get to overclocking again.

Well, Grant, with your enthusiasm and positive outlook I'm not surprised you excel at this.

We often see problems with overclocking. I'd seriously weigh the benefits against the problems it can cause which are manifold. But I am not a gamer, only an installer and Win7 guy.

After a new install I always check the logs and system resources, assure a Clean Boot for best performance, and other steps described in the tutorial.
