09/12/2015 23:11:41 | SETI@home | Task 05jn15aa.25293.8656.438086664204.12.200_0 is 90.48 days overdue; you may not get credit for it. Consider aborting it.

Aside: I'm "subscribed" to this thread, once because I clicked on the "Subscribe" button, and, I suspect, also because of my posts, but I've gotten NO emails to tell me about new posts here. Is something amiss with that feature of these boards?

Like I said before you posted again:

It's possible that the project you had work for has none at the moment. That's something you have to look up on the project's website.
It's also possible that you returned only errors and are at your maximum amount allowed errors in a row, that's also something you can look up on the project's website.

Your log also shows that, in some sense:

Hope you downloaded the correct version, i.e. the 32bit version of the installer as I'm sure the 64bit version will not work on XP. Else try this one https://boinc.berkeley.edu/dl/boinc_7.6.9_windows_intelx86.exe

If you would like to give a chance for a newer test version, there's 7.6.15 :

BOINC will auto-update the list. You may need to restart the client, though. Not sure. I just opened it and had the new list.

Currently, I can't see it - which log file, should I expect to see the details?

Some years ago, I bought a Samsung N220 laptop, with Windows 7 (Home version) on it, for general use - I updated it to 2048 MB RAM, the maximum allowed. I added some BOINC programs to it and everything seemed fine.

Did the project servers go down? I received 3 tasks, which have since completed, but the data refuses to upload. It will say 'uploading' for about 2 or 3 minutes, upload no data, then 'attempt to retry in [several hours]'. Meanwhile I have 11 days 39 hours worth of data sitting on the computer. I don't want to abort it and have it go to waste...

To force uploads, open BOINC Manager, Advanced view, Projects tab, select the project of choice and click Update. The Update command will immediately upload any outstanding uploads, download outstanding downloads and report any work ready to report.

The homepage isn't even showing anymore when they will be back online :(

It's been like that for a long time. If you click his name, you go to Pasquale's page, but he hasn't said anything about the project for quite a while.

Use at most N% of the CPUs set to 90% only dropped the number of tasks from 9 to 8. It still won't use more than 20-25% or so. I don't think anything is overworked. It's more like under-worked...? I don't know why.

The only way to resolve such errors is to try different drivers until you find one that's more solid than the rest.
