My advisor there sent me here to post a HJT log.
Short recap of problem and fixes i tried so far:

Problem: I'm running Vista Ultimate 32-bit on a self-built machine, E6850, 2 gig DDRII RAM.
Since 3 days now my computer started running really really slowly whenever i start something new…
The CPU total load goes to 100% when for example i open IE, when i log onto msn, when i open a picture, when i click something… if i'm not doing anything new the CPU load returns to normal and stays that way usually until i click something new and then it takes off again.

Fixes:
-Check add/remove programs for anything unusual (clear)
-Run CCleaner, Disk Cleanup, Disk Defragmenter, Spybot, SuperAntiSpyware, MBAM: all clean
-Check Device Manager for problems (clear)
