Recently I have purchased and installed a Asus GTX 550 Ti and started crunching GPUgrid aswell as Docking@home... I am having trouble getting Boinc to connect to the locahost since installing the graphics card.. and sometimes it happened before that so im not sure its graphics card related..

Boinc version is 7.0.28(x64) Running Windows7 64bit Pro
Intel core i7 with 8Gb of ram..

I don't seem to get any errors other than the usual stuff about trying three times and not being able to connect..

Now and again with some fiddling I can manage to get Boinc to run fine but 99% of the time it will always fail..

Boinc.exe starts up but then after maybe 20secs it will stop running...

There are no error logs in the way of Boinc or anything in text files in the Boinc folders..

In Windows event viewer there are errors showing an APPCRASH for boinc.exe

I am pretty much at my witts end with this... so any help would be amazing :D

When BOINC is unable to connect to localhost, something is blocking it. Most probably your firewall, but otherwise your anti-virus or other anti-malware program(s).

Localhost is your computer.
It's a loop-back address at IP address 127.0.0.1 that BOINC uses to do communication between its parts. When you did not allow BOINC through your firewall, or did not tell Windows 7 to allow boinc.exe and boincmgr.exe to have access to your private network, then it will complain about that.

Boinc.exe itself needs internet access through TCP ports 80 and 443.
Boinc.exe and boincmgr.exe need to be able to talk to each other through TCP port 31416.

Make sure that those are allowed first. It may also stop the client from crashing.

Thanks for your reply Ageless I have read extensive amounts of your advice on these forums and followed everything you've said already... :)

All AV/Malware/Firewall software have exceptions in their lists that lead back to my Boinc installed files.. Both installed to different locations but not the defaults...

What is strange that on reverting back to an older 6.something version of BOINC last night before leaving the house seemed to fix the issue... rebooted 4 times ina row and it was all working fine... that's what's strange is the issue has only arisen since moving into the BOINC 7.0.28 version :/

It's rather frustrating and as I said boinc.exe keep's having APPCRASH's and shows up in Windows Event Viewer...

Once I get home later I will post more details and some screenshots... happily crunching away on BOINC 6....

Was the Data directory moved after you exited BOINC and prior to the installation of a new one?

What I mean is, people do all weird kinds of things.
They'll move BOINC stuff around while BOINC is still running and then complain that what they moved gets deleted. Or they install BOINC, exit it, then move the whole data directory to elsewhere, then just restart BOINC. But it expects the data directory to be at the old place, so it'll just remake a new one, and then people will complain they 'lost all that work'. They didn't..

So, how did you move the directories to different locations, where are they now and are all the permissions on the directories in check? Or perhaps they are now, now that you installed BOINC 6 and it fixed the permissions.
