Normally I consider myself very proficient when it comes to electronics/computers, however I am having a bit of a hard time tracking down an annoying thing that randomly makes Outlook or other programs go into 'not responding' mode. I will try to explain the situation and what I did so far as good as possible. - it does not help to 'wait a bit' as is sometimes the case, even after 15 mins or more and no load on the system the program will not recover, the only solution is to kill or restart the program - procmon etc. did not help so far as no process seems to be behaving abnormally. - disabled truecrypt (still happening), disabled anti-virus ...

System: Lenovo T400 with Win 7 32 bit, 2,53 Ghz, 4 GB Ram, 500 GB Hdd (replacing the original 320 Gb), Intel and Ati switchable graphics (set to discrete in bios atm).

Should I check the disk for errors? Should I run memtest first or replace some memory sticks? I just think that if it were the disk or ram, problems should be more widespread or if they occur freeze more than one program. Any ideas appreciated.

Initially you might check the Event Viewer (Right-click "Computer" on the Start menu and select "Manage") for signs of errors being caused at the application level. –  Paul Jul 22 '11 at 17:10
I'd first track down when it does this. Is this when Outlook loads? Is it when it sync main? etc etc –  surfasb Jul 22 '11 at 21:37
