My laptop HP Pavilion dv2000 AMD TURION 64X2 DUAL-CORE. The laptop, after a short period of time working, freezes then the blue screen of death appears. If I wait a little bit, it will reboot by itself. I went to Microsoft updates plus the Nvidia and also to HP website to see if I can get any help. I tried everything and they told me to do but it's still freezing, blue screen and shooting down / rebooting again.
