I've had this prob with other versions of windows especially on newer high end systems which ended up needing a BIOS update to correct the situation however sometimes it was due to a bad memory stick..not necessarily bad but some portion that windows is trying use durring install but might normally not be accessed is hit and windows installer chokes (windows the OS has no prob with it in the end).

Try taking out all the mem chips and replacing one by one..verifying they count up on screen durring boot and display properly in bios...flash bios to latest version,...then pick just one to insert durring the install...if same..try diff single stick...also disconnect any unecessary devices like printers or add in cards, etc to reduce the possibility of some freak memory address or IRQ conflict for good measure

i heard that it may happen as a result of 32 bit drivers running on a 64 bit system. is that a possibility? and if its true how would i go about id'ing that driver without having to uninstall every driver and install one by one each time waiting for a blue screen. thanks

if you can get to device manager you could r-click properties to see what version driver you have for any device in question. Running a game from an external HD and having the same prob only indicates the issue is with the system or it's configuration not eliminate any problem really. It just verify's it still exists
