Windows 7: Crashes on Win7 Logo - Safe Mode Works

Crashes on Win7 Logo - Safe Mode Works

Hi, this morning my computer randomly locked up and needed to be restarted. Now it will not boot normally, only in safe mode. When attempting a normal boot, it sits on the normal Win7 loading screen for 4-5 seconds and then goes to a black screen with the computer still running. No error messages, no BSOD, mouse/keyboard are dead. The only way to get any response is to power off then back on.

I have nothing plugged in except for the mouse and keyboard (they both work) - I also unplugged my storage HD with no result. I have reset the Bios to default settings and optimal default settings - no luck. The whole computer is relatively new (2 weeks old), but I have not installed any new drivers or hardware since the initial setup. Windows automatic update is on (This is probabyly the culprit? I don't know for sure)

Originally when running the startup repair, I was getting a badpatch error. Now I'm getting ExternalMedia. I can provide the details if needed for the repair failure message ( just need to run it again)

I've looked through a lot of tutorials on this site, so far:
-Turning off processes in safe mode and trying a "clean boot" does nothing - it still freezes at the same point.

-I ran both an antivirus and malwarebytes scan in safe mode - neither found anything.

-System restore tells me it cannot complete due to an unknown error (no other information). Despite this, when I load in safe mode it tells me it was successfully restored. I tried all four restore dates and none would boot normally.

-chkdsk from command prompt reports no bad sectors, completes successfully.

-The sfc /scannow from command prompt completes succesfully and reports no errors.

I'm about to give up and to a complete format/clean install, but I want to avoid that if at all possible. Any ideas?

Well, I went to run the startup repair again so I could give full details on the error but now its telling me it can't find a problem. Despite this, the issue remains - Win loading screen -> black screen (monitor active, no command prompt, no mouse/keyboard, no BSOD or other errors)

I also want to say I tried the "Last Succesful Boot" option with no success.

Thank you for the response. I did read and follow that tutorial, I've done everything up until the point of backing up files and doing a clean install. I would really like to avoid that if possible so I thought I would see if anyone had ideas.

I feel like this should be fixable since safe mode is working, I just don't know what to do. I also looked into doing a repair install but since I can only start in safe mode that isn't really an option.

Thank you.

I enabled boot logging and looked at the file in safe mode, there are a lot of drivers failing to load but its so many that I can't tell which one is the problem (or even if this is the problem).

Have you considered using System Restore? You can start it while in Safe Mode. Start, All Programs, Accessories, System Tools, System Restore. Choose a date before you started having problems.

Yes, I have 4 system restore dates available and tried them all. It gives me an error saying the system restore cannot complete, but when I start in safe mode I get the popup saying it has been successfully restored to X date.

Regardless none of the four restores will boot normally, only in safe mode.

Post a camera snap of the Partition Wizard drive map and listings, which you'll have handy if you completed all the Troubleshooting Steps for Windows 7 steps.

Which AV scans did you run and what found? SFC results?

Hi, so theres a pretty massive update but still the same problem.

I decided to just go ahead and reformat/clean install. Everything goes fine, I start installing drivers and then this problem starts again.

Long story short, as soon as I install the drivers for the GTX 760 my PC won't boot. I system restore to before the drivers and its fine. I've tried multiple versions of the driver, always the same problem. There was a beta driver release yesterday - I do not know if GeForce experience automatically installed it or not.

The thing that makes this so weird is although its a new build, it was running perfectly for a week with the latest stable driver installed. Now it no longer works - this is after a completely fresh format and Win7 install.

Could my card have died? It runs fine without drivers, but as soon as I install them Windows 7 won't boot. The install is always clean with no errors, it just wants me to restart and when I do the problem occurs.
