hello ...
all i can see is a lot of processes launched at boot time, that may cause a slow-down or even a conflict. some files are unknown to me, so may also be a malware infection.
try removing most of non-critical processes by using msconfig & uncheck the items on 'startup' options.
i would consider: the smartdefrag, asus, nero, java update scheduler, apple bonjour, google bar & update, chrome addon, groovemonitor, quicktime task, adobe reader, punk buster utility,
i see that you have a logitech webcam, steam installed & 2 AV + hijackthis launched at startup..
after doing this you may proceed with a full system scan ... hope you get this problem solved as soon as possible ...
cheers!
