Just recently installed Windows 7 x64 RC1 (Build 7100) on my HP DV6000 notebook, it has core2duo and integrated video card, etc.
The main issue I am having is that, everything works just fine (even faster than vista sometimes, which originally came with my notebook), but randomly, the system will stop responding (everything about it, the system will even stop sending data packets out over wireless or lan), and the harddrive light will lit up (not blinking just constant lit). The mouse usually can be moved about but it cannot be used to click anything. After a few minutes the system will go back to normal. This is absolutely horrible when I am playing a game, as I would have to keep my fingers on the keyboard just incase the game would "defrost" suddenly.
The same issue also happened when I install the 32bit of Windows 7 rc1 on the same notebook. However this is not happening on my P4 notebook (IBM R40) so I can only assume that this is a hardware issue. But I have no references/parameters on how to trouble-shoot this. Anyone got a clue?
