Before few days I got some weird hangings on my mech. Symptoms are that windows starts about 4 times slower, mouse pointer is hanging as I move it over the screen (and almost nothing is being runned at the time), the same most of times when I scroll web page in FF and if I open a PDF while listening music from winamp, music get stopped for a moment, the same if I try to compile something - all CPU gets consumed by the compiler, which was a minor run before... in total, something went very wrong, resulting this mech being much much much less capable of anything than it was.
I consider to replace pasta on my CPU but since the CPU temperature isn't greater than it was, I wonder whether this will fix anything. The next consideration is Windows reinstall.
I have only essential applications in startup and even some of services are shut down. No new software installed lately. HDD defragmented the last week. I observed processes with processexplorer but no foreign processes so far.
Any ideas?

Newest entry. While doing backups, I saw one more symptom, that is probably most close to the truth. Mech was unable to burn a CD without several read buffer underruns on (16x), which is just ridiculous as it was able to burn without having read buffer fall for a single percent before. Will look if DMA is activated when I finish this burn.

Strangely, everything works in PIO mode, although it worked in DMA before. I am able only to tell it to use "DMA if available", but it uses PIO. I do not see way to force it do otherwise. File system is NTFS and the disk is less than 40% full.
Any suggestions?
