Drongar~ The Xentor 32 ships at a default clock speed of 175mhz, so it should work out of the box at that speed.
Nameless~ It may be because of heat, open up your case and leave the cover off and see if it still hapens. My case temperature rarely goes over 30 degree's, unless its 30 degree's in the house, in which my case goes up to about 33-34 degree's.
Sounds like you could use a little more cooling in there. If you can get your case temperature down and the problem still occur's, get it exchanged.
