so, everything is fine when i start up my computer. i can open programs, play games, and my aida sensorpanel updates every 4-6 seconds-- easily verifiable by watching "up time" ticker. the world is happy.
then i go away for an hour, with only chrome or other inconsequential programs up. when i come back, the sensorpanel shows one core (which core it is varies) at 99%, all other ones at 0 or 1, and appears to have frozen. nothing updates, including the up time. however, the entire system has likewise become unresponsive. it can take 5 mins to launch task manager or a new windows explorer window. right clicking on the aida64 icon in the notification area sometimes will result in the menu showing up after a few minutes, but most of the time it never does. even if i have process explorer or something similar up before the hang, i am usually unable to close aida at this point. regardless of whether or not i am able to exit AIDA, i have to reboot before my system becomes usable again.
a couple interesting things:
-- any application that was open prior to the issue continues to operate fine (including demanding 3d games), but i am typically unable to close aida or start anything new, no matter how small or trivial the process.
-- the issue still appears to occur even if i never manually start AIDA64 and have it set to not autostart with windows, but uninstalling AIDA64 fixes the problem.
-- the issue is 100% reproduceable. all i have to do is walk away from my computer for 2 hours.
note that while i do have an ATI video card, i have disabled ulps via registry and have the latest drivers.
any help would be greatly appreciated.
i will edit this to attach my aida system dump shortly-- im in the middle of a long download and i don't want to reboot until it has completed.
