The system dopes not seem to recover until I do a reboot. And I have thought it could be a MS update, there were about 5-6 updates that came down last week.

No I didn't. I have lost almost a day fighting this issue, for now I disabled the service and startup programs (there are two). If someone knows what's going on that would be great, otherwise I really don't have the time to just trying guessing what the problem could be. At least the problem is documented, I have never seen a late model computer bogged down as bad as this - fan on high and the look of Windows 2.1...

Yes, Sgt.Joe, and I might add that as you start adding tasks, keep them to one science only.

Speaking of the date, is the time correctly set on the laptop, and the battery good? (One of my old PCs balked a little, until the time was correctly set, the battery was on empty.)

Good internet speed?

According to Bios, what is the memory speed?
On mine it also lets you know if the memory it optimized, Asynchronous, Interlaced, or something.

Hard disk defragmented?

Does Win7 have an easy button to set computer for optimum performance over appearance?

Is 16 Gigabytes of virtual memory not a little way too much? The cpu is only 2GHz and the cache is only 256K

...just noting things

(For when there's further time to troubleshoot)

Sorry to say, but with these numbers, bionc running or not, the system Should not be slow, what is happening to the other 80-45% CPU and 65% memory that makes it unavailable and therefore boggs the system????? The numbers just don't add up, SOMETHING is running to use these resources, and as you say boinc is running, and included, (causing the slow down) it must be elsewhere.

awalt,

With Windows 7, when looking in Task Manager there may be a button, left bottom, to show all processes for all users. The 65,000 dollar question being if it's any of the WCGxxx science apps eating CPU time or boinc.exe OR boincmgr.exe. The WCG apps of course take any spare cycle, but latter 2 should not but are known to go rampant on CPU time and or memory for some, myself having observed that in past times [AT VERY RARE OCCASIONS]. Both should not, and use only few minutes a day, at worst a quarter of an hour, if the BOINC manager is kept expanded on screen and little to nothing if the interface is closed or only showing as systray icon.

Your log shows that BOINC is installed as service, so Task Manager must be run as admin, or that ''show all'' button has to be operated in TM to see everything. You can add columns to TM to shows total accumulated CPU time per app and service, then sort them on that column so you can see which are the big consumers.

Unless it is boinc or boincmgr or a wild gone boinc science graphic gone zombie, concur with fredski, that something less benign or heavy is running. Disk and memory diagnosis could eliminated those elements as outside chance sources [and an aggressive AV, but that often leads to tasks actually failing].

Let us know.

PS, as to reducing temps and keeping fans in check: Suggest to fetch TThrottle [written specially for BOINCing] and set a temp ceiling, mine set to 65C. Then on Windows XP > 7, it will automatically slow down the BOINC science apps... only the science apps, AND any other app you program it to slow down that eats lots of CPU time, when it's hot.
