Cannot access graphics hardware
Hi

I posted earlier about an issue I'm having with a newly-installed Asus GTX 770 (here). I've spent most of the day trying to find a resolution to the crashes I have been getting while gaming, initially saying 'display driver stopped responding and has recovered', however I'be been unable to find any that have worked.

Incidentally, when a game freezes for a few seconds and then crashes to desktop, it is now saying 'Application (Metro 2033 for example) has been blocked from accessing graphics hardware'. Has anybody had the same issues? The GTX 760 that has just been taken out worked fine and had no issues whatsoever. I have also uninstalled all drivers and then reinstalled them but with no change.

Could it be an issue with my PSU? The minimum recommended for th 770 is 600w and I have a Corsair CX600 - unfortunately I have no way of testing a new PSU without buying one however. My GTX 760 is boxed and ready to be sent back, however, without rectifying the issue with the new 770, the latter will unwillingly have to be returned instead.

Any advice would be hugely appreciated.

My full specs are:

Asus GTX 770 2gb
i5 4690k
MSI Z97 Gaming 3 mobo
8gb RAM
Corsair CX600w PSU
Windows 8 Pro

Thanks!

Two days without any issues and it has just crashed again. Back to the drawing board...

Glad it seems OK.

Update... I've just done a clean driver install and also taken out the leads from both the PSU and the card, reinserting them in the other sockets (tightly). I've also just played Metro 2033 for 20 minutes without a crash.

It may just be coincidence, but fingers crossed....!

The driver should not be a problem, the 770 uses the same driver as the 760.
It's either your PSU is not supplying enough power, or the 770 is simply bad, which I believe is more likely. If the 760 works fine, send back the 770 for a RMA.

Sounds like a good start. Do you have an extra PSU you can try?

Does the 770 have extra power requirements- such as 6pin connector? If so, was that connected tightly?

Thanks for the info. I've uninstalled the drivers and then done a clean install of the latest Nvidia driver for the 770 but have still got the problem unfortunately. I'm going to put the 760 back in and see if that is working correctly, which could suggest it is a PSU issue maybe?

I don't know of an equivalent...

Have you tried to remove the drivers yet?
Control Panel \ Programs and Features
Fine the NVIDIA items and remove them all.
The PC will have to reboot.
Install the drivers for the 770. Download them from the website, not from the cd-rom that came with the card.

Hi Cowboy, thanks for your response.

I'm not overclocking anything, no. It's my first build, which I completed a couple of weeks ago and everything was working fine. I initially had an Asus GTX760 in it, with no problems at all, then swapped it for the (again Asus) GTX 770 last night. I've since had constant crashing and the error messages when gaming.

I'm fairly new to this, so I'm stumped (as well as being thoroughly frustrated!) with the issue. What sort of clean-up utilities do AMD cards have and do you know of any Nvidia equivalents?

Thanks again

I have no experience with NVIDIA, however with AMD there are some clean up utilities.

Maybe someone else has more info on this, but maybe that is what caused it.

If the minimum recommended wattage is 600 and you only have a 600w PSU, then that could be doing it.
The GPU only uses a max of 230w though. Are you overclocking the CPU, GPU, or RAM?
