My machine has been a loyal servant for the few last years, got it new, and it was fine. last couple of months it is giving me hell. long hangs with no apparent reason (I run AV, and constantly scan my computer for evil beings - not spyware).
The only indication for anything is given by the wonderfull Process Explorer which points that “Hardware Interrupts” are the ones giving me the grief. However, I have no special hardware connected anywhere, and no change has been made to my configuration before this horrible behavior begun.
Today it took me over 15 minutes just to restart my machine (after trying to get windows to even show the restart dialog).
I'm switching machines! a slightly newer with more and faster memory.
P.S. if anyone has an idea on those hardware interrupts, I'll be glad to investigate, as I'm keeping the old one “as is” for now.
