Yesterday boinc started locking up my computer. Version 5.4.11

The system is a winxp with a core2duo processor running boinc for seti and climate research using the windows firewall and avg antivirus.

The symptoms are as follows. Whenever I enable boinc, even with the projects disabled, the system starts hitting the internet hard. After about 20 or so mouse clicks the system pauses, the monitor blinks off then on, then locks up completely. There are no messages in the message log to indicate any problems. With boinc totally disabled the system runs normally.

I thought perhaps I had a trojan or virus so I scanned for viruses with AVG. This didn't show anything so I switched to zonealarm. This didn't
help. I am running an optomized version of seti.

I am wondering how I should proceed. Should I uninstall and reinstall boinc? Is there some trojan or logger that piggybacks on boinc? Is there some setting I need to set in order to clear up possible bad data causing this?

Thanks,

Scuba

Could you try two things:

* See if Prime 95's torture test runs OK for a few hours

* Try turning the network actiity off in boinc and see if you get the same problem

Turned off network activity and it hasn't locked up yet. Looks like the connection is still being hammered although I can't get any indication of
what is doing it. Zonealarm doesn't show anything being blocked, yet the traffic icon still shows lots of activity.

The system has been stable and isn't being taxed by any means. Memory rated for much higher than I am running it. Haven't run prime in a while but had no problems with memtest at higher speeds than running now.

Thanks for the reply. Do you have any idea what it could be?

Oops, just locked up with network activity off.

I'll try prime next.

Thanks,

Zone Alarm shows local host (127.0.0.1) traffic when Boinc is running. That's the way Boinc components communicates with the manager.

Perhaps zonealarm shows traffic, but my system locks up. I can't explain it.

Prime95 stable for almost 4 hours, no errors.

Prime95 stable almost 4 hours with no errors.

Perhaps the lockups have nothing to do with the network activity.

Any other hints or possibilities?

Thank you,

Since your system locks up even without a network connection, have you checked:

1. heat.
2. event viewer.

Heat is not a problem, cpu at 35C in a case that has 6 case fans. Mushkin high performance memory. Event viewer shows nothing. The cpu pauses, the monitor blinks off then on again, then it locks up totally. This occurs only while BOINC is running. Prime95 stable for almost 4 hours before I shut it down with 0 errors. Completely stable otherwise.

Thank you,

Are you using the screen saver? If so, did you check if your GPU fan isn't clogged up with dust?

And else, still open your computer after shutting down and clean out the dust bunnies inside. Especially in the heatsinks!!

Have any results crashed due to this crashing of BOINC? If so, please leave me a link to your computer on the project you are crunching for.

Uninstalled and reinstalled BOINC. Seems to have cleared the problem up. Lost a couple of work units in Seti and some great headway in Climate Predicion. Sorry about that for sure.

The freezing didn't seem to upset the seti program itself, just the computer when surfing.

New motherboard, processor, heatsink, graphics card, memory, new OS. No dust bunnies in this baby, I'm a computer fanatic! Yes, this is my bag baby!

If it happens again I'll let you know.

Thank you

Bummer, but at least CPDN uploads it's progress as it goes (so it's only work since the last trickle which has been lost).
