This article names a protein that might help recovery from strokes. Could someone at GPUGRID check if there has been enough work to determine the 3D structure of this protein?

Mouse Study Suggests Stem Cells May Reverse Stroke Damage

This still needs tests to determine if it also works in humans.
Looks unlikely to help recover memories lost in strokes, but may recover the ability to form those memories.

Beyond, the 362.00 folder now appears there; it didn't under safe mode with command prompt.

skgiven, backups to what? My disk server no longer works, and backups to DVDs stopped working for me years ago. Setup Repair apparantly did the fix, but then told me that it had not been able to fix anything.

C:\Windows\System32\drivers contains many files, none of which have names that make them look likely to be Nvidia drivers.

Apparently, the program for creating restore points will create them only on the last drive you list as a place to put them, but the program for using restore points will ignore all those which aren't on the C: drive. So if you list more than one drive as places to put them, don't expect them to work.

Exception: The 368.22 driver does NOT work well under Windows Vista. If you install it there, expect many hours for which the computer won't even boot.

BOINC started and agrees that 362.00 is installed. I'm going to let it run a while before I do much more.

In case you're wondering, the GTX 560 in that computer is still inadequate for GPUGRID. So is the GT 440 in my other desktop.

By the way, using safe mode with command prompt, I was able to find some directories related to driver versions older than 362.00, but none that appeared to be related to 362.00 or more recent. Where on the hard drive should I look to find the CURRENTLY INSTALLED Nvidia driver?

... and now will not boot, either normally or in safe mode.

Robert did say he's tried to boot in safe mode but that it wouldn't start.

I presumed he tried all the likely options but if Safe Mode only was tried I would try Last Known Good Configuration next and then Zoltan's suggestion - it's the one people forget to try, "Enable low resolution-video (640 X 480)". If it boots, uninstall/hack out the failed driver and install a working version, clearing the registry.


One of the programs I ran from the installation DVD that tried to do a repair and SAID that it wasn't able to do anything actually restored my ability to do normal boots, and safe mode boots with command prompt.

Geforce Experience now says that the currently installed driver is 362.00 and offers to install 365.19.

I'll try to start BOINC and see if it agrees that 362.00 is installed, before I make any other changes.

Robert, you may be able to perform a Repair Installation on Vista if you have a Vista media disk.
http://www.vistax64.com/tutorials/88236-repair-install-vista.html
You might also be able to boot to a W7 disk and use some of the disk tools or commands to check for problems, or just boot to a command prompt and delete what you can of the driver.

You might also want to try removing and reinserting the GPU:
Turn the system off, remove the GPU, start up the system, let it fail. Turn it off again and then insert the GPU. When it boots up again it might detect the GPU and install default display drivers or prompt for the drivers.


That link calls for steps that require preparing a DVD on the Vista system you want to repair. Since it will not boot, that cannot be done.

I found the Vista media disk. I tried everything it offers that does not require losing all my data. None of it appeared to help, but I'm now able to boot to a command prompt, which did not work before.

I'll see what the W7 upgrade disk offers later.

Do you mean removing and reinserting just the GPU, or the whole graphics board?

My backup device hasn't worked for the last few years. My last usable backups appear to be from 2010.

I've been trying Cygwin under Windows as a way to start trying Linux; it still looks rather difficult to do much.

I don't have a usable way to take it to Windows 10 quickly, but do have a set of DVDs to upgrade to Windows 7 Ultimate. I might try that if it allows me to put Windows 7 on a separate hard drive that is almost ready to install.

I've decided that Windows 10 has very poor methods for finding programs that do not happen to be in a reasonable place on the Start menu.

What I've seen so far indicates that 368.22 fixes the problems (including one CUDA problem) if it will install properly - but the installation fails on some hardware/Windows combinations in a way that makes the computer unbootable.

It installed properly on my Windows 10 computer and is running without errors.

However, on my Windows Vista computer (Intel Q9650 CPU, GTX 560, 8 GB memory, 64-bit Windows Vista SP1), the screen went black perhaps halfway through the installation, and stayed that way until I turned off the computer about an hour later. Attempting to reinstall 362.00 ended with messages that newer versions of some parts were already present, and were not changed. The computer has gone downhill over another 6 hours and now will not boot, either normally or in safe mode. While I was still able to run the hardware diagnostics, they reported no errors. System Restore will not run.

I've already reported this to Nvidia, but can any of you suggest what to do to make that computer run properly again?

I have no information on whether this problem also affects CUDA tasks, but for OpenCL tasks, one task crashes after a few hours, then perhaps two dozen more (not necessarily from the same BOINC project) crash quickly. Restarting Windows appears to be required to make any more OpenCL tasks complete properly.

The OpenCL section of the Nvidia 364.72 driver, and earlier 364.* drivers, has a problem which can cause an entire computer to lock up, or cause a few dozen OpenCL tasks (often not all from the same BOINC project) to give a quick Compute Error. Problem not seen in the 362.00 driver.

Tasks from POEM@home seem the most likely to trigger this problem.

I currently do not have hardware that can check whether GPUGRID has this problem, but you may want to watch for it.
