HP Pavillion DV7 Notebook PC
Intel Core 2 Quad CPU Q9000 at 2GHz (64-bit)
6.00 GB RAM
64-bit Vista Home Premium SP1
I am a computer application programmer and have a lot of experience with XP, but mostly as a user. This is my first Vista machine and I have little experience with Vista, but I can find my way around it...eventually. (I'm used to finding configuration options in XP and have to search a little to find the equivalent option in Vista.)
Quite frequently, when I am using my machine, it goes into an "unresponsive" or "thrashing" state. By this I mean the hard drive light goes on continuously, and some or all all running applications become unresponsive (they don't respond to clicks and keypresses, eventually showing "Not Responding" in the title bar). Usually Explorer and the task bar and start menu remain functional but sometimes I get the spinning ring of death. Control-Alt-Delete causes the screen to go black for a few minutes before the prompt comes up.
Sometimes this happens with the Task Manager open. Sometimes Task Manager becomes unresponsive too, but when it doesn't it appears to show only 30% processor usage, and only about 2Gb of RAM are in use.
The most frequent program I use when not programming is Windows Live Mail, and the problem seems to crop up when I'm reading and browsing e-mails, and Windows Live Mail seems to be the first to exhibit the problems, but that's probably coincidence.
No error messages. Is there a system log that I should be looking at?
Sometimes in Task Manager I've seen WERfault.exe running - does this mean a background process is crashing? How can I get more info on that?
The problem started soon after I got the machine. The first time it cropped up, I turned off SuperFetch and the problem seemed to disappear for a few days, but after a windows update, the problem returned just as bad as before.
The machine never totally hangs -- if I wait around for a few minutes, eventually it finishes whatever was tying it up and all applications become responsive again. But this occurs quite frequently, 5-10 times per hour, and thus it is very hard to get work done.
