On 2 out of 3 of my Win7-64 PCs (all PCs run CPU as well as CUDA tasks), BOINC Manager stopped working properly after updating to SP1. Here are some of the symptoms:

1) Whenever I try opening BOINC Manager, I get a Windows error message saying BOINC Screensaver has stopped working.
2) BOINC Manager window is generated, but it says it is "Communicating with BOINC client. Please wait". The BOINC Manger window disappears in a few seconds.
3) If I remove boincscr.exe, symptom 1 disappears, but symptom 2 persists.
4) Using the command line "boinccmd --get_state", I'd get a Windows error message saying "BOINC Command Line has stopped working".
5) This is the beginning of the error entry in stderrgui.txt:
- Unhandled Exception Record -
Reason: Access Violation (0xc0000005) at address 0x0000000140150B68 read attempt to address 0x00000080

Has anybody seen this problem?

I should also add that this appears to be strictly a GUI issue: tasks appear to run normally as seen in Task Manager.

---

it looks like all buy 1 of your windows 7 PC's has a GPU that appears to be running seti.

I would have assumed that you already knew that you can't run BOINC/seti screen saver while running GPU WU's the GPU cant do both. so you can either turn off the screensaver or not run GPU WU's while the screen saver is on.

Thanks for the response. Actually all 3 of the Win7 PCs run CUDA tasks, and I run the screen saver in none of them.

Incidentally, the 2 offending PCs have been running as they have been after I uninstalled the SP1 update. I stopped short of saying running normally since 1 of them has always been having sporadic problem with the BOINC Manager GUI: symptom 2 would occur sporadically, especially when in the Tasks tab.

How many tasks are downloaded (more than 1000)?

Do you show all tasks or active tasks in the Tasks tab?

could have mentioned in your first post in addition to this

1) Whenever I try opening BOINC Manager, I get a Windows error message saying BOINC Screensaver has stopped working.

That you are in fact not running the screen saver. Your message implied you were.

Have your tried reinstalling BOINC making sure the "use screensaver" is unchecked.

googling 0xc00000005 gets this

Stop 0x00000050 or PAGE_FAULT_IN_NONPAGED_AREA

The Stop 0x50 message indicates that requested data was not in memory. The system generates an exception error when using a reference to an invalid system memory address. Defective memory (including main memory, L2 RAM cache, video RAM) or incompatible software (including remote control and antivirus software) might cause Stop 0x50 messages.

Possible Resolutions:

• If you added new hardware recently, remove and replace the hardware to determine if it is causing or contributing to the problem. Run diagnostics software supplied by the hardware manufacturer to determine if the component has failed.

• Stop 0x50 messages can also occur after installing faulty drivers or system services. If the file name is listed, you need to disable, remove, or roll back that driver. If not, disable the recently installed service or application to determine if this resolves the error. If this does not resolve the problem, contact the hardware manufacturer for updates. Using updated drivers and software is especially important for network interface cards, video adapters, backup programs, multimedia applications, antivirus scanners, and CD mastering tools. If an updated driver is not available, attempt to use a driver from a similar device in the same family. For example, if printing to a Model 1100C printer causes Stop 0x50 errors, using a printer driver meant for a Model 1100A or Model 1000 might temporarily resolve the problem.

Stop 0x00000050 or PAGE_FAULT_IN_NONPAGED_AREA

It's two distinctly different errors. If you want to help around here, make sure to Google and post info about the correct error.

Stop 0xc0000005 is not equal to Stop 0x00000050
For Stop 0xc0000005, also know for short as Stop 0xc5, related information, go here: http://msdn.microsoft.com/en-us/library/ff560192%28v=vs.85%29.aspx

Not sure if this in any way or helps, but all of my systems that run windows 7 64bit (total of 4), did not even flinch at the update. Everything running as normally compared to before the update. Do you have any other programs that where affected by the update?

Sorry, didnt page down far enough, and wireless is acting up. Looks like u have plenty of help on it.

0xc0000005 is not the same as 0x000000c5

The former is "failed to initialize properly".

BOINC WIKI

How many tasks are downloaded (more than 1000)?

The number of tasks downloaded is <500. I have all tasks displayed on all 3 machines.

Have your tried reinstalling BOINC making sure the "use screensaver" is unchecked.

Pretty sure I've done that. I have just reinstalled BOINC and made absolutely sure that option is unchecked. Will report back later if this helps.

---

Also go into the Control Panel and change the screen saver to something other than BOINC. I prefer the blank option.

Reinstalling did not help with SP1: even with the screen saver option disabled during installation and the Windows setting set to "none", I still get the error upon Windows startup and any time I try opening the BOINC manager. Had to remove SP1 yet again to have things running normally.

---

Not sure if this is going to help, but I had a problem similar to that about 8 months ago, right before my hard drive crashed. Tried all kinds of things and nonthing would take. I hope you are not having the same problem, but I could not perform a restore to an earlier date. I started backing up all important files, but eventually the hard drive failed even after passing multiple scans and tests.

That was not on a Win 7 machine though.
