This started about 5 days ago. I started to see computation erors and work units that normally take a few hours to complete, completing in less than a minute.
I have McAffe running full time, with everything the application has, running. I have run a full scan using both McAffe and the Microsoft Safety app. It's not finding any issues. One of the first indications was an error that said the Microsoft C++ runtime app had a problem, I have re-booted, re-installed from an earlier date etc.. I also ran CC Cleaner on the system.

I'm at a loss, it is only affecting 1 computer of the 3 I have crunching numbers.

Any help would be appreciated.

I've suspended SETI until I can get this resolved also

First place I would look. Have you checked the temps? Maybe a dust bunny raid is in order.

Short run times, and affecting both CPU and GPU....
Just a crazy thought, is your AV software playing games with the way S@H writes stuff to the disk? I had it recently where my AV decided to play silly on one of my crunchers - cured by excluding the BOINC/projects directory from AV activities.

funny you should say that, I was just thinking the same thing. I haven't blown out either of my systems in about 3 months. Although I keep them off the floor, the cat hair and dust still gets in there. :-) I'll do that today...

I did a blow job on the system :-) compressor.. it reduced the temp about 20 degrees but the system wasn't that dirty. still having the problems with SETI. I think I'll just turn off McAfee and see what happens. I have already (again) run the microsoft safty app and and McAfee scans and they didn't pick up anything.

At first sight looks like temps - but with some memory errors and hard crashes thrown in I'm suspecting hardware - not my area of expertise, but checking the RAM and such can't hurt.

ok, I blew out the chassie and it reduced the temp over 20 degrees F. I wasn't near the max but it sure seemed to help, went from about 150 degrees to 127, systems says it can't go over 181. Not having the issues at this time, everything seems to be running ok. guess I just need to clean the chassie more often.
thanks for everybodies advice.

I overclocked the system from 2.8 to 3.87 , think I'll just run it at it's normal speed. may help until I can get my swamp cooler serviced. Ya I'm in Arizona, no air conditioning in my house. Today it reached 96 :-)
