Careful with Driver Sweeper, toxiclum. Be extra sure you investigate the items the utility is about to delete. It appears you already have a problematic dll file. I'm not sure, but the faulting module path you're getting may be pointing to a corrupt video driver. As far as I know,
nvoglv32 (64) is a hidden Nvidia system file. Mine is in the System32 folder, I think.
Anyways, here are the steps I take when installing new drivers or replacing an improperly written driver:
1. Remove old driver.
2. Run driver sweeper in safe mode. ( I do this twice, but then I'm OC about these things.
)
3. Reboot into normal mode.
4. Install fresh drivers (I always choose the "Clean Install" option) and reboot.
I recommend that you re-download the 301.42 installer from the Nvidia website. Don't use the copy you have on file on your hard disk.
Have you tried using Windows 7 driver verifier to correct the dll problem? I've had some success using that utility, but -- again -- you shouldn't be messing with these things if you don't have enough information about them yet. Proper removal and installation of the driver in question should be enough.
Also, have you considered using the driver that came with the 680? I eventually solved my problems with 301.42 by simply moving on to another driver -- and a beta version, at that.
I'm sorry I couldn't be of more help.
PS: This is going to sound like a shot in the dark, but you might want to check your system for malware, just in case. Also, just to be clear, your GPU load cranks up to 98% just after restarting? D'you mean this happens before you pop open any apps? Sounds really strange, if that is the case. And what temps are you getting? Your thread title indicates overheating.
Sorry about all the questions and the editing. Just making sure everything I'm getting everything correctly.
