a) Get it fixed?
b) If you mean a730W, it's a 2003 system on a 2004 device. That was over 7 years ago. Is that what you base your Windows experience on? You cast an error prone system as the inability of a giant corporation to write code? I see.
Anyway, let us try some logic. * It was definitely not doing that when they sold it, otherwise it would have been returned and melted for scrap.
* The quality of code doesn't diminish with time. Hardware stability and performance does.
Add those together and it's pretty clear to me you have a hardware problem.
Not a software fault. So, bottom line is, get it fixed.
