Message 1511078 - Posted: 2 May 2014, 4:25:01 UTC

My AMD 955 (4-core with GTX-570 GPU) blew a power supply while running Windows 8.1. I attempted to get it running with an old spare supply but lost all the WU's and then it started powering off. I rebooted it with Windows 7 which had a different set of WU's in process which were also all lost. I reinstalled BOINC 7.2.42 and Lunatics 0.41. Now the instant a WU completes the download it immediately says COMPUTATION ERROR. The only ones I've seen show as GPU tasks but I'm not sure if that is accurate. I don't have a clue what is happening and hope someone can help. I had modified the XML file to run 3 GPU tasks at once but tried restoring the original with no change.

The "Can't write init file" error is coming from BOINC. When trying to start a task the first thing it does is set up the shared memory to communicate with the application, that's not erroring. But the second thing is trying to write the init_data.xml file into the slot and that's what's failing. It might be a permissions problem, maybe doing a repair install of BOINC would help.

Thanks for the reply. I did do a Repair of BOINC followed by a removal and reinstall and a reinstall of Lunatics bit that didn't help. I'll keep working on it.

Look at the Antivirus logs, is it blocking something BOINC related?

Thanks to everyone that replied. I had a power supply that blew up which started this problem. I replaced the supply today and sill got the error but I booted Win 8.1, which kept powering down with a temporary supply I had installed. It's running Seti with no problem. If I decide to boot the Win 7 partition I'll probably do a partition restore from a previous backup before starting BOINC again.
Thanx,

Bob B.
