I am using a latitude E6510 with Windows7 64 bit.
I am getting frequent, random, momentary hangs - 50 or more in an hour.
I can be typing, or searching on the web, or pretty much doing anything, and the machine will hang - the mouse pointer will stop and go to a green circle - or the cursor will stop while I am typing and then several letters will cascade in to catch up. It's most maddening when I am listening to music from a web site and it will jutter or buzz.
I can watch the resource monitor and often the hang will occur when the computer is accessing the disk drive and the cpu usage goes up. The cpu usage isn't that high - a few percent to a few tens of percent - but it will spike, and the hard drive will spike - and I get a hang. I've done a scan using microsoft security essentials - nothing found. I've reduced the programs on my startup menu; I've rebooted. I've looked at Task Manager to see what is most active and don't see anything unusual - csrss and firefox are most active... Nothing I've done seems to affect it, it still randomly hangs.
Other possibly relevant data: I recently loaded identity finder and trucrypt - but see no difference whether they are running or not - and they aren't loaded in the startup menu as far as I can tell so normally I am not running them in the background.
If this thing is getting set to meltdown on me, I'd like to be prepared for it - but otherwise what do I do to get rid of this. (and it's probably hung twenty times while I was typing this)
Thanks for any advice.
