I have a new laptop running Vista Home premium and have had no problems at all. However, Windows update has not offered me SP1 automatically so there must be a device or something that does not like Vista. I ran the Microsoft Vista upgrade checker and it tells me that my GeForce 8400M GS will not work with Vista ! It obviously does as it is working fine and I have just finished Half Life 2 Episode 2 on it. Perhaps it needs a Vista version of the driver, but from what I can see, it has ! Very odd and for the time being I have not installed SP1 from disc. Should I install it or leave well alone ?
I have discovered that although I have the latest driver for this card, it is in a Samsung R700 and the Nvidia site advises that I should only update drivers via the Samsung site as the drivers are adapted and tweaked by Samsung. I presume that it is this that causes Microsoft to not recognise the card as non Vista compatible and thus not offer an automatic upgrade to SP1. I shall leave things be but thought that this info would be of use to other Samsung users out there .
Nuts, this may be a daft question (and apologies if it is) but how new is the laptop? We bought a new laptop a couple of weeks ago and it has SP1 preinstalled. Was Vista preinstalled or have you installed it over a version of XP?
I know you've probably checked for this, but I thought I'd better mention it cos it could take some users unawares that they already have the Service Pack, and could be waiting for it unecessarily.
For what it's worth our laptop is running SP1 with no issues at all, and even my desktop (which took it on itself to download and install SP1 (even though I'd originally turned auto updates off) doesn't seem to have suffered for the installation.
