I would very much appreciate your inputs into this problem. I've tried everything i could think of and looked everywhere for a solution over the web. I have been living with that problem for about 9 months now and i'm about to get «the hammer solution».
From time to time, with no predicable pattern, one process on my computer goes toward 99% cpu usage. It is often msnmsg (last 2 versions at least) or outlook (2003), but it can be others.
When i become aware of it (extreme slow down) I can manage to call the task manager (CTRL-ALT-DEL) as it will show up about a minute later. I can then kill the faulty process.
This is when it begans to spirals downward, after i kill the first process, it will jump to an other (apparently random) and this one will show 99% cpu usage. I can continue to kill those processes until i reach explorer itself and then the patterns will stops.
From there, there is two possibles outcomes. If I try to relaunch explorer, the system will hang (not freezing really, but going so slow that even the task manager becomes unusable) and therefore i have to reboot it. The other possibility is that i use the task manager to call a reboot of the system. Then i will have again a serie of (99% cpu usage) terminate promt that i will have to terminate before i reach the login out screen and then everything comes back to normal.
After the reboots, everything works fine. But the problem could arise again rigth away, after one hour of after 5 days with multiple shutdowns and/or sleep/deep sleeps.
I have been in the computer fixing business for 16 years and it is the first time i cannot see/find what the problem is... and it is on my own computer (doh!). It is NOT a problem with a malware/spyware/virus i can assure you.
Thank you very much for any input.
(BTW, one subproblem i have is that i cannot figure what keywords i could use to even make searches for that problem on MS site or google... i allways get results about very different problems)
