I have a Windows 7 professional 64bit desktop PC. Intel Core 2 quad, 1TB disk SATA2 (plenty of free space) , 8GB Ram DDR2.
I generally access the machine over remote desktop and always have.
I have a few user profiles defined but I have a problem with profile 'terry'. It can be running fine for a few days and then suddenly run so slowly that is can't render the screen completely over several hours.
Whilst in this state, if I attempt to log on directly at the PC and not remotely it sits at the 'welcome' message with a wait cursor forever.
What is confusing is this: Whilst in this state, if I log on remotely using another user, 'kate', everything is fine for that profile.
CPU is at 30% with csrss.exe running at 25%.
Resource monitor tells me that disk IO is low and response times are sub 50ms
From task manager I can see that terry is logged in but disconnected and that kate is logged in and active. Exactly as I would expect.
If I disconnect from kate and connect as terry I see the same problem as before.
So kate is running fine at the same time as terry has ground to a halt!
I have many programs installed and have started to experience this problem after I:
Updated Avast anti-virus program,
installed CrashPlan backup client and service,
installed Private Internet Access VPN,
installed Adobe LightRoom.
I have spent ages trying to eliminate the culprit but since it can take a few days for the problem to show it will take a very long time to get through the list. To make it worse, I thought that I had the problem solved when I removed all of the above programs the re installed crash plan. it ran for longer than it would normally take to halt. then I installed Private internet Access VPN and all seemed fine. Then I installed Avast and all seemed fine. then I installed LightRoom and all seemed fine.
Then after a week (continuously on), when I thought the problem had solved itself, it ground to a halt again. and now it's back to grinding to a halt every 1 or 2 days.
So before I start this process all over again I have a question to ask that may help me.
My question is simply this: What kind PC activity can cause one profile to crash whilst another is running fine? Maybe then I can use this answer to prioritise my re-install process.
Thank you for your time.
