Solved Windows won't start when graphics drivers are installed

September 12, 2012 at 13:27:14
Specs: Windows 7
Hello Forum,

Today while watching a Youtube video in fullscreen, my computer froze up completely, so I hit reset.
After the "Loading Windows" Screen(the one before the welcome screen), my monitor went black and cycled through inputs as though no signal was found.
By booting in safe mode, i was able to uninstall my graphics driver(I even used Driver Sweeper to get rid of everything related) and my computer was able to boot normally again.
Now, whenever i try to install a graphics driver(any driver, even old ones and the one that came on the CD) I get that black screen when (re)booting.


No new hardware was installed for months before this issue, nor did i update my graphics drivers recently.
I've been googling for about 3 hours now and tried most everything.
Tomorrow i will try out an old graphics card, but i really hope this one isn't broken already since it's not even a year since i bought it.

My Specs are:
Intel i5 2500
4GB RAM
Nvidia GeForce GTX 570
Windows 7 Enterprise 64-Bit

Your help will be very much appreciated.

Thanks in Advance,
Myst

Hello!
I was able to fix the problem by simply reinstalling Win7. seems like it was a software problem after all.

Try getting the latest driver direct from NVidia only for your card. Don't trust anyone else.

Run Malwarebytes in Safe Mode to make sure that it is not caused by malware.

You have not supplied information on your power supply and this information could be very important. If the power supply was marginal in it's ability to power your GTX570, it may no longer be able to power it (especially if it is one of those cheaper brands). Please supply the make and model number as well as the wattage and especially the amperage on the 12Volt rail(s) since this is what is needed to power your card.

You have to be a little bit crazy to keep you from going insane.

The key here is the freezing that happened when u were watching a youtube video and the pc froze, youtube videos or any video tend to use cpu power and graphics power, i believe what happened here is that there was to much power that the psu could not handle it and it froze the pc.
Lets hope nothing has been damaged, id like to ask where did u download ur drivers ?
download the latest from this website
www.geforce.com
install then in safe mode and mention ur power supply

Hello again,

my power supply is as follows:
XFX PRO850W Core Edition Full Wired Power Supply

However, i don't think my PSU is the reason for this. I've been running this system stable for over a year without any changes to the hardware. I've also been running demanding games(bf3, the witcher 2, etc) on this machine without it ever overheating.

I downloaded my drivers exclusively from the official nvidia website(nvidia.com). I always chose the stable versions over the beta builds.

Thank you for your replies thus far.

Myst

The power supply is good has more than enough juice to handle the setup.
Try the onboard graphics or as u mentioned earlier ur older graphics card does it boot ?

Your power supply should be fine.
If you do not have it, install HWMonitor and make sure that your temperatures, fan speeds, and voltages are normal at idle and when doing something involving graphics (game, etc.). This may lead you in the direction to look.

Don't overlook the possibility of your browser needing cleaning out (cookies, history, temp internet files, etc.) or some malware, especially if you can run a game without repeating the problem you had with the YouTube video.

Oh yes, the bigger hammer approach. Effective. Once hardware/temperature was ruled out, I would have tried a System Restore before the reinstall, simply because it avoids the reinstalling of everything else.
Glad you got it up and running again and thank you for letting us know.
