Hi everyone! This issue has been really frustrating and I've found no solution, so here we are!

I updated my Nvidia drivers for the first time in months. I was on 364.72, and decided to upgrade to the newest one 368.39.

Halfway through the install, it asked to restart the PC and continue the driver install. I told it to restart... and ever since, my PC no longer boots. Stuck on the "Starting Windows" screen and never gets past it.

Things I've done:


  • Tried to do startup repair, it found no issues (one time it attempted disk repair and fixed something, but still didn't let me boot in after that)
    Tried to do a system restore, still no dice
    Tried to boot into Safe Mode, but it hangs after loading /windows/system32/drivers/CLASSPNP.SYS" (regular and Networking safe mode)
    Tried to boot using last known safe configuration, still hangs.

Here are my specs:

Windows 7 Ultimate 64 bit
16 GB RAM DDR4
EVGA GTX 970
MSI Z170 mobo
CORSAIR CX series CX750M 750W PSU
Intel Core i5-6600 @ 3.3 GHZ CPU
2 tb HDD

I'm at a complete loss as to what to do... any suggestions? Thanks in advance :)

I'm going to try reseating the RAM, and if that doesn't net anything, I'll try taking the GPU out and seeing if it boots with onboard GPU. Will update my post so future googlers can see what my resolution was. :)

try to use the on board graphic and see if you can boot , according to i5-6600 it has a intel HD integrated.
if that didn't work try to do these steps:
1-put the windows installation disk/usb
2-in the installation menu click on "Repair your computer"
3-start the command prompt
4-type "sfc/scannow" to fix the windows problems

Tried this, and the command prompt told me a repair was pending and needed to restart. I booted again through the w7 installation disc and went to repair, and now I get the error "This version of System Recovery Options is not compatible with the version of Windows you are trying to repair. Try using a recovery disc that is compatible with this version of Windows."

Any ideas?

Unfortunately it just goes back to the Starting Windows screen and the same issue happens.

I tried a few of the reboot.exe cmd prompt commands and now system restore seems to actually be making progress -- if that doesn't work I'll try the onboard graphics!

Nope, using onboard graphics still gives me the same issue of hanging at the Starting Windows screen.... what do y'all think I should do next? I have no idea what to do at this point.

OK, so I'm not sure what the direct fix was, but once I got to a point where it successfully restored the system to a previous date, when it restarted I didn't directly boot in. I mashed F8 to run Last Known Good Configuration, and that did the trick!

Whew. This saga is over!
