As mentioned earlier, there are sometimes pretty funny but some are pretty hard to guess. like a HDD would hang but only if you do something for which you need heavy HDD usage. while the normal working nothing will happen, until you make something heavy. (and HDD hangs means Windows crashes).
It happens 2-3 times a day, then stops and my PC works fine again! Until I got the idea to replace the Y power cable! And now my PC works again! =)
Stunning!
