I have no problems with my setup
Last hardware problem I had was 3 systems ago, when I had a P4 1.6a clocked to 2.4Ghz. The mobo blew up, altho that was down to a crappy QTec PSU blowing after 12hours of use

. I replaced it with a intel mobo and gave it to my dad

he is still using it as his home system.
You must all be pushing stuff too much or something.
