my laptop was running vista home premuim 64bit but i installed windows 7 on it and its giving me problems when starting up....
I have decide to reinstall Vista Home Premuim and realized i only have the 32bit version. Will it be ok to install a 32bit OS on a 64bit system?
If the laptop ran 64-bit Vista you should have no problems at all with the 32-bit version; presumably this means that drivers are available for all the hardware.
It's a bit difficult to answer your other question. It could be anything, but I would suspect either a corrupted driver or a hardware problem (although that seems unlikely if it was OK before the upgrade); but as I say it's difficult to be more specific than that offhand.
