The only thing new on my PC are the Windows updates, it will be interesting to see if others experience this. It's certainly not impossible for it to be a rogue Windows update - as, I'm also running Windows 7 64 bit, and every now and again, my system does slowdown for a minute or so, and then speeds back up. As yet, I haven't been able to nail it, but when it does happen, in Windows Task Manager, the 'taskmgr.exe' basically uses up a core as a whole load of other tasks come in (which can be as many as two dozen)... Other than BOINC, what else are you using the machine for - just the odd bit of e-mail/surfing, gaming, playing DVD's etc.?  |

Have you ran a hard drive diagnostic to make sure it is not malfunctioning? Some apps will stress the drive more then others. I recommend Western Digital's Data Life Guard software.

I have been clicking show all processes. The BOINC threads are not taking excessive cycles, but I havve done a dozen tests where turning off the BOINC service stops the problem. awalt, As one of the posters in this thread laid out, if nothing but BOINC sciences are eating the CPU time, then on a quad the sciences should be showing near 25% CPU time use for a quad and near 12.5% for a Octo, (provided the BOINC throttle is set to 100%.). If the throttle is on, you say it's set to 60%, and the "Run Based on Preferences" has been selected, then you'd see alternation "per-science", between 0 and 12.5% CPU cycle use and the bulk of the pause time going to system idle processes. At any rate, if you add that CPU time column to the TM and sort on that, you can see what is accumulating the time. My Windows disk indexer with over 200,000 files takes about 1 minute a day, but has the BOINC data dir explicitly excluded. Something is rogue since BOINC sciences run at very lowest level priority... yield to anything else when it's needed. --//-- |

The 1969 date is very odd. To me, it looks like what Sgt. Joe says - the system starts really cranking up (maybe due to the 1969 date? Bug in one of the projects?), The 1969-date means you've never changed the WCG-preferences on the web-page, so shouldn't be a problem, but just to rule-out this you can do any changes to your web-preferences, save it, and going-back reverting to the previous settings.

Well it took about 7 hours of running but now my laptop is slower than molasses. It's running on only 4 of 8 CPUs, 60% of the time. CPU usage (all threads not just mine) ranges between 20% - 55%, memory usage is 35% of physical memory. 4 tasks are waiting to report, 2 running, 2 running high priority. "CPU usage ranges between 20% - 55%" implies that the System Idle process should range between 80% and 45%. If not, then a hidden process is running on your system. This is not a helpful suggestion, but the mystery is frustrating enough that I am considering paranoid options. Lawrence |

What would be really useful here, is a screenshot of your Windows Task Manager when your machine is running like molasses, showing the Processes tab, with at least the following columns selected (sorted on 'CPU') 'Image Name', 'User Name', 'CPU', 'CPU Time'. These can be selected by going into the View drop down menu, selecting 'Select Columns', and ticking the respective columns, after which, pressing the 'OK' box to activate them.
----------------------------------------Please ensure that, the box at the bottom left hand corner (Show processes from all users) is ticked, as then, we'll be able to identify what's going on... |

Something else to think about, high hardware interupts can cause a system to be sluggish and have high cooling fan spin which would make the computer seem to be under a heavy load. I used the Sysinternals Process Explorer to help confirm a hardware interupts problem on a Dell computer. Dell's hardware diagnostics confirmed it was a bad motherboard.

Yes, idle process will be high and the system will be very very slow. So odd. That's why I think the CPU has een scaled down, but on this computer (Dell Precision M6500) I don't see any place to see what speed the CPU is running at. Does CPU-Z report actual speed the CPU is running at?
Guys and gals, it really isn't the CPU % or memory. I KNOW how to turn on all processes and see them in Task Manager. Hard drive is a SSD. No errors in Event Log. Interrupts is a good thought. I'll get the process viewer app you suggested and see what it says. On this laptop I pretty much just browse, Office 2010, and some personal apps that would not be running (like Quicken). Again to review, one day I slowly shut down everything, and it still happened. Only through mscconfig was I able to narrow it down to WCG service (see first post). Thanks for your help! For now I have it uninstalled as I am leaving for a trip and I can't debug it any more. I'll be on email to check suggestions, I am building a list for when I get back. |

Can the suspicious updates be safely removed?
----------------------------------------On XP I see updates when I click on 'Add or Remove Programs' in the control panel, and it tells you on which date each update was installed. Is boinc itself slowed down? I wonder how fast one single task of HCC or some small task would run, provided it's a 64bit task, then compare with others. My 32bit computer, for example, runs a 32bit HCC in approx 2 hours, and if I turn hyperthreading on in Bios at startup it runs 2 of them in about 4 hours.

CPU-Z shows the actual CPU frequency.
As it's W7 and you recently installed updates, perhaps the power settings were reset. You should have these on high performance. Did you install a GPU driver update recently? |
